What buffer and buffer springs are compatible with this Stabilizing brace?
Jeffery on Nov 11, 2019
BEST ANSWER: I received a carbine length receiver extension (buffer tube) with it, so that’d be the norm. I however, opted to use the A5 system which utilized a rifle length extension, I absolutely love it.

Excellent product.
Worked out perfectly. I wasn’t sure how this would fit if I chose to run the A5 buffer system, but it turned out flawless. Dark Hour Defense makes an A5 length extension and it has 12 positions, which allows this brace to fit perfectly the whole length.

Great Brace!
A good improvement. It got Four stars because I think they should supply the castle nut and the rest of the lower parts that are required to install on a lower for the price being charged.
