JMac ST-6

Not my first purchase from JMac and won’t be my last! Very impressed with the durability of this stock adapter without it being too heavy. Using it with the B5 Bravo stock and it looks great.

Bought this for BRN180. Super lightweight, solid hinging mechanism, and buttery smooth when adjusting length of pull. Zero wobble with MFT stock. Looks badass.

got the Akm-rsa then got this bc the sig stock i wanted was sold out. i was considering getting the midwest ind folding a2 buffer tube untill i found out how much it weighed. a good friend of mine just saw this set-up on my rifle and almost lost it he has the magpul Zhukov folding stock and i could tell he wants a jmac now! running the moe buttstock and it folds flush in any position i do not have an optic rail. i think that a magpul sl stock that i was gonna get would have been too wide to be flush in all positions. i really like my whole set up a whole lot better but have 380$ into the folding stock it so thats kind of pricey

AwesOme, whEther fixed or folded

This skeletonized tube is a game changer for wanting an AR style collapsing stock on on an AK. Runs smoothly with 1913 folding mech on pistol Note: If you combine with skeletonized tube with the folding mech, have a slimmer brace/stock if you want to have a more flush fit. Another great product! Well done Justin, Ash, and JMac Team!

ST-6 for my 7.62 Gen 2 Pistol

Absolutely love this stock! My first time purchasing from JMAC and the quality is superb. I purchased the adapter with this, and it fit perfectly. It folds easier now and locks into place nicely. I thought it needed to be like an inch longer, but it actually feels really good in position 3 and 6. Overall great product. A++++

Jmac Folding Mec ST-6

Written by Reece D. Nors on Sep 2nd 2021

I got one of these guys for my BRN-180 Build and it couldn't be any more perfect. Not only does it look awesome, it's much more stable than some of the big name side folders out there. A buddy of mine also has a BRN-180 build with a certain name brand stock off of one of their snake guns and it would begin to fold in on itself if you put too much pressure on it while shooting. The JMac does no such thing, its easy to deploy and break down and there is no wobble. Super glad I went with this option and not with what so many other people are using. Besides being different, it's good to know i've got a stable platform on what is now my main shooter. Quality, application, and cool factor are all there, can't recommend enough.
