Nice work CBC


I saw some mixed reviews on this company on the internet but since they are veteran owned company I gave them a shot and ordered one of these uppers. I got it and it was WELL worth the money. Runs like a watch and shoots sub moa. I just ordered another one

Solid performing budget upper

by -

Purchased this upper because of the 1:8 twist, cost, and rail setup. I have a few 1:7 barrels, but a lot of light .223 and 5.56 ammo, so I picked this up to use for those rounds. Dropped right on to my DSI milspec multical lower, and fits nice and tight. First day out to sight in a Nikon prostaff, I sent 270 rds down range, with zero hiccups, but did notice that the BCG seems to eject inconsistently, compared to the black rain. Not a big deal, but I wanted to note it. The grouping at 100 yds is unbeatable for a budget upper. All sub MOA after zero. No working of the feed ramps, no tweaking of the barrel. Just drop in and fire. I'm very pleased with the performance of this, especially when you factor in the price of the BCG and charge handle.

Very happy
