It's a very secure compartment door designs, and it's very unlikely to open accidentally. To keep items from rattling around inside, they can be first put into a small ziploc or cut down sandwich bag then put into the compartment. It actually works very well, and I prefer the grip angled to the front than to the rear. The slight angle helps lock the hand higher up on the grip where it transitions to the rail.
The flattened profile of the grip also provides more rotational purchase than a cylindrical grip - something that might come into play when lowering the carbine with the support hand while the other hand goes to the pistol during a transition to pistol. Like pistol grips, vertical grip choice depends largely on hand size, shooting style and personal preference.
Attachment method and grip texturing are identical, so please refer to the previous writeup on the standard length GFVG for the details of those features. Storage compartment - While the SHORT shares the same type of hinged trapdoor opening to the storage compartment as the standard GFVG, the storage compartment is obviously shorter and less roomy.
I was just able to fit two AA batteries in the compartment. Even so, the rubber seal on the inside of the trapdoor will deform slightly to accommodate them. A single CR battery will fit inside it. A handstop is generally a bit short for my liking and a standard length vertical grip is longer than I need.
I've shot a lot with and without vertical grips on my rifles, and keep coming back to stubby grips as they're easier on my wrist for most positions than no grip at all. The reason I like short grips is because my normal hand position only makes use of the first two or three inches, so I don't have need for the longer standard grips.
My middle finger is usually at the transition between the handguard and the grip, so basically I have half my hand on the handguard and the other on the grip. This is where the slight forward angle of the BCM vertical grip helps lock the hand higher up on the grip where it transitions to the rail. I've really come to appreciate the flattened profile of the BCM grip as it provides more rotational purchase and control than a cylindrical grip.
The texturing on the sides and ridges on the front strap ensure a good grip with and without gloves - something I wish the TangoDown stubby my other favourite vertical grip had more of. The mounting base is actually a bit longer than the Picatinny, and the base is only about. The both share the same flattened grip cross-section with laser-textured pattern on the sides and horizontal ridges at the front and back.
The interface consists of two KeyMod studs and a recoil lug, requiring three KeyMod holes to mount. The studs are actually screws that hold the top plate onto the mounting base. The plate has a recoil lug that when pushed up from the bottom, engages the KeyMod hole in the platform and prevents any forward and aft movement of the grip. In its 'relaxed' postion, the lug sits below the surface of the plate, allowing the grip to be slid on or off the platform.
The lower grip section screws into the mounting base, and has a 'plug' that pushes the recoil lug upwards when the lower grip section is tightened. The lower grip section is locked in place by a spring-loaded serrated slide latch.
To attach the grip to a platform, the slide-latch is pressed upwards so that it disengages from the slot at the top of the lower grip section. The lower grip section is then unscrewed. BCM's instruction state to rotate the lower grip portion counter-clockwise a minimum of two full rotations. I found that one full rotation is enough to lower the recoil lug and enable the grip to be installed and removed from the handguard. The lower grip section is then screwed into the base, where the plug pushes up on the recoil lug and the spring-loaded latch locks.
It's very quick and easy; and very convenient. It'll still accommodate a single AA battery, as the plug that pushes up on the recoil lug is hollow and serves as a AA battery holder. By having a direct-attach grip on a KeyMod handguard, you eliminate having to mount an adapter rail on the bottom of the handguard.
Being mounted closer to the handguard also provides a smoother transition between grip and handguard. Mounted up, it's solid and I can feel no movement at all. The top of the grip could have been made more narrow - straight up and down at the top or with less flare, which I think would be an improvement for me, at least. It's something for BCM to consider in the future. Some of the key features are:. The Mod 3 does not have the trapdoor storage compartment that the Vertical Grip SHORT has, and utilizes a new, very low profile method of attaching to the handguard.
Picatinny Version - The Picatinny version of the Mod 3 utilizes an 'anchor' which draws the grip towards the rail when the T15 Torx screw is tightened. The anchor is secured to the grip via a square nut and screw which is tightened from the inside of the grip.
To install the grip, a T15 Torx driver or wrench is used to loosen the screw and extend the anchor from the top. The anchor and grip are then slid onto the rail.
When the desired position is reached, the grip is pushed against the rail where the front and rear of the base of the grip engage the rail's cross slots. The screw is then tightened to approximately 40 inch-lbs plus a quarter turn. Blue thread locker may be used on the screw if desired. This Picatinny anchor design allows the base of the Mod 3 to be smaller than that on the BCM Vertical Grip, since it doesn't have a clamp that needs to open up.
The main difference is that the Mod 3 needs to be slid onto the rail, which necessitates removing any rail panels or other accessories that may be in the way; while the BCM Vertical Grip can be rocked onto the rail without sliding it on.
The Mod 3 is also slightly shorter, and lacks the storage compartment. Instead of a Picatinny anchor, it has a metal KeyMod anchor with two studs that engage the keyholes in the hand guard. It utilizes the same T15 Torx screw to snug the anchor to the rail, accessed through the bottom of the grip. To install the grip, the screw is loosened then pushed in with the T15 tool driver or wrench so that the studs protrude from the base.
The studs are inserted through the large holes of the desired KeyMod slots, and the grip is then slid forward. The screw is then tightened and the grip's recoil lugs engage the KeyMod holes, prevent it from slipping back. The screw is then tightened.
I really like the smaller base of the Mod 3 vs. BCM's other vertical grips. The metal Picatinny anchor idea is pretty innovative as it allows the base to be narrower than your standard polymer dovetail or clamp.
You do give up the convenience of being able to 'rock' the grip onto the rail without having to slide it from the front. Doing so requires the removal of any accessories you have in front.
The smaller base on the KeyMod version really makes a difference, in my opinion, as it improves the transition between grip and handguard. I would, however, like to see a Mod 3 with storage compartment. The Mod 3 is half the price of the Vertical Grip SHORT, which is going to be very appealing to those who just want a simple, no-frills grip that just plain works. It was designed primarily for vehicle use and aircrews, or when storage and transport space is limited, and enables the user to put the weapon into action faster than a separated upper and lower.
Because of this, the AR is limited to a collapsible stock to achieve a reduction in overall length, whereas the other weapons listed can accommodate folding stocks or stocks that collapse almost completely.
The ability to fold or collapse a stock is primarily one of convenience in transportation, storage, and handling in tight quarters. A smaller package is more concealable in a non-permissive environment and allows a wider variety of transporation modes bags, cases to be used.
While an AR upper and lower can be carried disassembled and then assembled very quickly when needed, it's not very practical if a case or bag isn't available, and the user just wants a fully assembled weapon that can be shortened for tight quarters and put into deployment quickly.
The Law Tactical AR folding stock adapter is a hinged assembly that allows a carbine stock to be folded along the left side of the AR, drastically reducing its overall length. This is the Gen 2 model shown here. Description - The Folding Stock Adapter is essentially a hinge assembly that installs to the rear of an AR lower receiver. The hinge assembly is made up of two main parts - the receiver side and the stock side. The receiver side is attached to the rear of the lower receiver, and a standard rilfe or carbine receiver extension then threads into the stock side.
Since the receiver extension has been moved to the rear by a small amount, a spacer in the form of a bolt carier extension is installed into the rear of the bolt carrier. The hinge assembly has a button which locks it in the closed position, and when pressed allows the stock side of the hinge to unlock and fold to the left of the weapon. The Folding Stock Adapter is designed to allow the stock to fold only for carry and transport; not for firing with the stock folded. Steel parts are made from steel.
It can be used with direct impingement or gas piston systems and fits any A2, carbine, mil spec or commercial buffer tube and stock. It can be used with standard bolt carrier groups including full and semi auto, 5. A QD sling swivel mount is provided at the bottom of the adapter. Manufacturing quality and fit is excellent. Operation - When folded, the stock lays on the left side of the weapon. There is no locking mechanism to hold it in the folded position, so in order to bring it into operation, it's simply swung around into the open position where it engages the button and locks open automatically.
When the stock is in the folded position, the rear of the bolt carrier extension is exposed at the rear of the receiver. It's prevented from sliding out further by the button, which partially blocks it. When the stock is locked open, the button moves to the left slightly to allow the extension to pass by it, and the carrier to reciprocate.
To unlock the stock, the button is pressed, and the stock folded to the left. The Law Tactical AR Folding Stock Adapter not designed to allow the weapon to be fired with the stock folded, and should never be done. The difference, as mentioned above, is that the AR cannot be fired with the stock folded whereas the others can. Testing has been performed on the Law Tactical adapter to see what would happen if the weapon was fired with the stock folded, and only minor damage was sustained to the adapter components - not to the host weapon.
The bottom line is - if threat is imminent, unfold the stock. Use the folding feature for storage, transportation and covert carry only. Deploying the stock takes one second. However, if the rifle needs to be stored compactly in a vehicle in a mount, or attached to a police motorcycle, it's impractical to separate the upper and lower.
Having a folding stock will ensure that the weapon is assembled and ready for deployment when needed in a pinch. Pros and cons - every product has them. The pros of the folding stock adapter is obvious; the overall length of the weapon is reduced by about six inches with the stock folded to the side. It allows the weapon to be transported, stored and carried in a much smaller overall package than before, and only an inch longer than the length of the upper receiver only.
The main con, in my opinion, is that the upper and lower cannot be separated without disassembling the bolt carrier extension from the bolt carrier. Some lowers will allow the upper to be slid forward and separated M full auto lower receivers with the thinner wall to accommodate the auto sear , but most don't. This is an inconvenience when it comes to maintenance, and I wonder about wear and tear on the carrier extension screw and expanding plug over time with repeated disassembly. The VC3 thread locker is pre-applied to the extension screw, and will need to be re-applied after a few cycles of disassembly and reassembly.
As I swap uppers and lowers often, it's a matter of convenience for me. For someone who has a dedicated upper for the folding stock lower, or has no need to disassemble it for frequent maintenance, it may be less of an issue. The other con is the location of the QD sling swivel stud - it's located on the bottom of the receiver side of the hinge assembly. With a QD swivel installed, it was a no-go for me, even with a smaller QD swivel. It was uncomfortable and interfered with my hand. That's why I installed my sling on a receiver end plate and recommend that a right handed user install something like the Noveske plate which provides a QD attach point at the rear.
Another thing I'd like to see is some kind of detent that keeps the stock in the folded position. Slinging the weapon with the stock folded when using the sling plate I installed wasn't possible because it'd pull the stock into a partially open position. One more thing to consider is the added length when open. When open, about 1. That's why I used a standard carbine receiver extension for this installation instead of the longer Vltor A5 tube.
I'm a smaller fellow, and when wearing a plate carrier need the stock almost completely collapsed. With the carbine tube and a Vltor i-mod stock, it was fine for me, but the longer E-Mod stock would have been too long. With the stock open and locked, the weapon functioned at the range just as it would normally. I didn't have any issues or notice any difference whatsoever, even though the carrier extension adds a bit of reciprocating weight. I'm using a H-buffer, and that can easily be swapped out to a standard buffer if the additional weight causes issues.
The stock locks up solidly in the open position without any play. Malfunction drills were no different, and there was no need to separate the upper and lower during the range session. I'd really like to see Law Tactical work on a solution that allows normal separation of the upper and lower - I've already brought this up and discussed what I feel might be an option - make the bolt carrier extension in two pieces: have the plug that installs into the rear of the carrier with a clocking feature that the front of the extension engages.
That way the extension can be removed out the back of the upper while the plug stays in the carrier. There'll be enough clearance to move the upper receiver forward and out to separate it from the lower. I think that that's the main concern I have with this design - the sling attach point and detent to keep the stock folded are secondary to that.
Law Tactical did design the carrier extension to be removed with a simple screw driver, and my multi tool works with it, so if there's an occasion where it really needs to be removed in the field, it can be quite easily. Playing around with the rifle in a car, it is much more handy and compact with the stock folded, and only takes a second to open. The Law Tactical AR Folding Stock Adapter was designed with a specific purpose in mind - to reduce the overall length of the AR for transport, storage, concealment and mobility while allowing it to be put into action faster than if the upper and lower were separated.
The current design, like any other, can be refined and there's always room for improvement. But if you have a current need that it will fulfill, and you've evaluated all the pros and cons, it's definitely worth checking out. All Rights Reserved.

Switched my BCM's to raptor's I do shoot lefty though. However, I would not buy them off amazon or ebay fakes are circulating. Buy them direct from Rainer Arms or a trusted retailer. I run the Mod 3 Large. I think its perfect but like everything else on a rifle it is personal preference. Switched to medium after large snagged on table while grounding and opend action just enough to cause misfire on reengagment.
