St-6

Written by Steven Perkins on May 31st 2021

Awesome product, mounted right up to my Sig MCX and fit a SB3 brace perfect!

Great Stock

Written by Clint Blumenberg on May 18th 2021

Lightweight, slick looking, and goes great on my MCX. It can be a little stiff to adjust positions, but I don't move my stock much anyway, so not a big deal. Great piece!

St6 skeletonized buffer

Paired perfectly with my arsenal adapter. Beautiful fit and finish. Absolutely no complaints

GREAT STOCK REPLACEMENT!

Written by Steven on Apr 12th 2021

Bought this to replace the stock pistol brace with a Magpul stock after I SBR'd an MCX pistol but still wanted the foldability of OEM stocks. Unscrewed the pistol brace from the 1913 adapter and installed the ST-6. Magpul CTR fits perfectly and now I have the best of both worlds - foldable stock but with my own choice of buttstock!

ST-6.

Seems like a well made quality product. Fitment and finishing is superb. Looking forward to seeing how it looks on my Arsenal 104rf.

ST-6

This was the perfect combo with the 1913 mech and a sba3 brace. Wow! It looks amazing and I have no complaints.

ST-6 adapter

Written by Todd on Sep 19th 2020

Ok, wow. This product exceded my expectations big time. I already had a Sig folder on my AMD with JMac adapter so i didnt order the ST-6 with one. Hey, do yourself a favor and order it with one. Trying to take out the Sig installed bolt was tuff. But once i got it on it is perfect! The Magpul M4 stock i used doesnt rattle on the ST-6 and lays almost flat against the receiver when folded. Top notch product

Great option for AR stocks/braces

Written by Michael on Aug 30th 2020

Picked this up to put on my Galil ACE. Paired it with the Sig folding mech. The JMac tube looks better on the rifle compared to an AR buffer tube. Excellent machining and fit. Stock fits perfectly on the tube.

Amazing Brace mount

Written by Nathan on Aug 26th 2020

I ordered this with the Sig folding mechanism for an MCX and used it with a SBA3 brace. This this is infinitely better option that the annoying spinning on the factory Sig brace. Solidly built, locks up amazingly, cannot recommend enough!
