This will complete my 300 BLK pistol build. It's perfect for this project. I must also comment on MAS Defense's selections and fair pricing and shipping is second to none. I have several more builds in the works and will stick with MAS Defense.

Great buffer tube kit
October 16, 2014
: Christopher K
It sets the sig arm brace at the perfect distance to get the "nose to charging handle" cheek weld. Great quality and the buffer runs great with subs and supers!

Typical MAS
October 15, 2014
: Paul J
As always MAS is the absolute best place I have found to buy parts for an AR build. I bought this buffer tube along with the sig stabilizing brace and had then in two ds, which is common every timeI have ordered from them. As usual quality is great and the prices were great.
