Great Completion Kit (20/02/2011)

This kit was better than expected; the receiver extension is of high quality manufacturing (Vltor). Mil-spec stock has NO rattle at all, also numbered positions are great for quick glance adjustment, no more counting clicks to get comfortable length. Metal coating is very scratch resistant. Over all great for a new build CAR-15 or upgrade of commercial stocked lower.

Mil-Spec Adjustable Carbine Stock Kit (16/11/2012)

Fit perfect. Not a single problem. My Magpul ACS and an older Vltor adjustable stock fit upon it and both are nice and tight. In the future I will order this again.

I paired this with an ACS-L Magpul (28/02/2013)

VERY nice fit here. Quality construction and it looks good too. Fit perfectly with the magpul stock I put on this rifle.

Great! (24/01/2012)

Was on "backorder", but shipped kit same day, Brownells is on point! Just received/installed new carbine tube, fit/finish is perfect. However, one thing i noticed that my existing tube doesn't have is a small maybe, 3/32" hole dead center in the end. I'm not sure of the purpose of this, but you'd think that it could let contamination of sorts in, so i was a bit befuddled. On the other hand, everything else was identical what i already had (- tube length, 6 position slots, slant back), but hey, now i have an excuse to build another AR ;) A+++

Easy to assemble (10/03/2014)

I bought the commercial carbine kit. This product is so easy to use, I was up and running in no time. I really like this product. And with Brownell's life time warranty, how could you go wrong. You won't be disappointed.
