Definitely recommended

Brownells USA Feels very sturdy. 08/04/2015

Used on a new build. Extension feels very sturdy, perhaps even slightly heavier that some other extensions on the market. Magpul stock fits nice and snug.

Definitely recommended

Brownells USA Good for the price 26/08/2014

Though this buffer tube isn't really mil spec its still got good fit and finish for the price. I recommend it.
