DSA AR15 14.7" Chrome Lined M4 1:7 Twist Sight Tower Upper Assembly - Pinned Flash Hider 16.4" OAL

I am very pleased with this upper. The original 16" upper I had purchased wasn't working out so I returned it for this model here. I tell you, I wish I went with this model from the start. Since I got this model I've run at least 500 rounds and had no problem. Cycles perfectly. I've swapped out the handguard for an extended quad rail but will be going back to the standard M4 handfguard for weight savings. This is for my first rifle and it's everything I could hope for. Installed on my Palmetto State lower w/ a Palmetto State BCG. When I'm asked what kind of upper to get, I direct people to this model here. This is the golden standard. Great customer support!
