Alexander Arms 16" 6.5 Grendel upper

[Mark Hartig]

Complete upper, about 100 rounds fired thru it. 16" barrel, 1:7.5 twist, AAC 51 tooth QD suppressor mount/flash hider, carbon fiber float tube. It seems to like Hornady 129 gr. SST's. The scope is a Nikon M-223 2.5-10 laser rangefinding.

Assuming anyone's interested I'd take $600 for the upper and $300 for the glass. Rangefinder in the glass works and the reticle will hold zero but I broke the front mounting screw and replaced it with a quick and dirty fix from Ace hardware hence I'm willing to part with it for that.

OR, I'm looking for an A4 20" upper in 5.56 with a 1:9 twist if anyone's got something comparable to swap

Is that the Alexander Arms barrel, 9/16x24 threading?

Yes it is this one was factory built
