ALAN O. on Jun 18th 2024
I didn't want to second guess my folding brace purchase and I am SO glad that I chose JMac Customs. The AB-8R Arm Bar is extremely high quality and really brings my build together.

5 Arm Bar, Brace Adapter, 1913 Folding Adapter, Forward grip
Jeremie on Dec 22nd 2023
Excellent product, solid build, Installed all these on my Sig Rattler and matching it with the Gear Head Works TailHook Mod 1C Pistol Brace, this a solid set up with no rattling noise or cheap plastic feel and damn does it look good. Took it down to my gun shop and had everyone checking this build out. One of the guys there liked it so much he bought a gun so he could run with this brace set up. All I can say is I am impressed and keep up the excellent products. I defiantly recommend this product and it is worth the money.

5 AB-8R
Albert on Oct 17th 2022
Excellent little stock that’s very foldable not only to the side but also the butplate if you get it. Works great and very good making your full-size AK more compact while looking good.

This folding stock is extremely stout. Im sure it can take one hell of a beating. It works and pairs perfectly with my cmmg dissent.

5 AB-9 arm bar
Tim on Sep 20th 2022
Bought the AB-9 arm bar cause my brace was to short. The AB-9 brought me right to the legal length for my particular application. As with everything I’ve bought or handled from jmac it’s exceedingly high quality! The fit/finish/coating are all top tier! Can’t recommend it enough. Best part is when my tax stamp comes in it’s a super quick swap from tailhook to folding buttplate!

5 Beautified my Brn180
Grant on Apr 2nd 2022
Didn't see any other choice for the BRN180. Wasn't sure but went w the AB-8R vs 9R and it feels perfect w the mod1 and .25 inch cheek riser. I probably would've gone w the 9R if I was using the folding butt plate. Pieces look and feel better than expected. I also snagged the extended HRD and realized it was too good on another setup. Had to make a few back-to-back orders and shipping was within a day both times.

5 Amazing
clint lemon on Jan 29th 2022
Simply amazing, not only is the arm solid but the folding butt plate is also outstanding and durable. I have 2 of these both on a sig 1913 folding mount one is mounted on my cz scorpion micro SBR and the other is on my sig rattler canebrake.

Butter fingers on Dec 7th 2021
Hands down, the nicest piece for your AK pistol needs. Very easy to install the tail hook and slap on to the folding mechanism.

5 Fantastic!
Mitch S on Oct 25th 2021
Nice quality product! This slight rise makes for a more comfortable cheek weld....

5 Light weight and sturdy
Billy B on Oct 14th 2021
I fitted this to my MCX folding brace with the AB-BA adapter and tailhhook. The feel and look of this arm bar is better than the alternatives, and the option for a cheek riser from Isle MFG is a bonus. The machining is great and it feels solid with no flex like the Sig plastic arm. The additional two QD points from the brace and arm are placed exactly where I need them, depending on how I want to carry with a sling. The rise is just enough that it clears the charging handle while giving that extra height that I was looking for. Great product and I will be ordering more for other builds.

5 Well made
D. on Jul 29th 2021
Lots of attention to detail on these. Good machine work, super solid despite being skeletonized. Good QD's, with anti-rotation. Tapped for a rest, if you want it. These were designed by someone who actually put some thought into it.

5 AB-8r with Tailhook Brace adapter and 1913 folding attachment
Mark on Feb 4th 2021
Mounted this to my Draco. Rock solid setup from the Tailhook Brace adapter and 1913 folder to the Stormwerks AK pistol adapter. Quality of work is on point! I highly recommend this. Thanks

5 Ideal on a MCX Pistol
Rainman.pnw on Oct 14th 2020
The only thing that comes close to this is the venerable (and discontinued) "Kate Moss" skeleton stock from Sig, but that is a stock, and then I'd have to go get a tax stamp. This setup, with the rise in the middle, the rock-solid Sig side-folding bracket, and a Tailhook Mod 1 make for an incredible light-weight, low-bulk brace on my MCX Virtus pistol offers the perfect cheek weld for running a Romeo 4T that is co-witnessed with the iron sights.

5 AB-8R Arm Bar
Axis on Sep 30th 2020
I have two of this version of the arm bar. I have had the fs1913, tf1913, and used the A3 Tactical brace adapter. The JMac version is by far the most solid. The design, durability, and aesthetics are second to none. The arm bar brought my build together. Jmac listens to customers and produces quality items that other companies just won't do. They truly care about their customer base and I'm thankful to have their products on my firearms.

5 Great product
CRIS Villanueva on Sep 21st 2020
Shipping was fast and product exceeded my expectation. All my adjustable braces and stocks fit nicely with very minimal back and forth play. ZERO twist, amazing fitment.

5 Made my gun perfect
Robert on Sep 19th 2020
After installing this I was instantly a better shooter, it added 100 points to my credit score, and even got me a girlfriend. Honestly though iys a great product it really helps with my brace and makes my gun so much more handy and makes the recoil more manageable and helps me stay on target alot better. I'm hooked I need another one for my draco now

5 Perfect on the mPx
ECossis on Jul 25th 2020
The Arm Bar fits and feel perfect on the MPX. No more bulkiness from the stock collapsible brace. Great product and looking forward to getting a few more. Cam assembled already as well.
