5 of 5 8.5" Spikes Upper September 25, 2017
: Eric P  
This is my third upper from Mas Defense. Enough said. I like it fast and I like Quality, and that's what I get 10 out of 10 times with this FFL. Couldn't ask for more.

5 of 5 a great build and fast service February 25, 2016
: Keith P  
I ordered the 8.5" 300 BLACKOUT BARRELED UPPER - TROY BATTLERAIL ALPHA 9? (which was actually the 7.5" SS 1x7 twist HBAR option) and I am very happy with it for my pistol build. Initial tests with supers (Remington 120gr UMC) have this build easily doing 0.25" or less groups at CQB distances (~10 yards) when I do my part. Subs are doing about the same. I'm still getting it dialed in so I can see how far I can push the system for how I intend to use it.One of the great advantages here is that the unit breaks down and fits one of my bags comfortably so if I wanted to, as a CCP holder, I could carry it with me.I would certainly consider another build from MAS Defense based on my initial experience.
