This is a green CAV arms MKI lower built with an A2 upper and a USGI profile (heavy out front, light under the HG) barrel that's been cut to about 17.5". It runs great, but won't lock open on the last round. Supposedly common with the MKI receiver. The OG handguards came from RRA. The barrel's kinda scraped up, but it shoots as good as any AR out there. I was just going to wait until the ban's gone to replace the barrel, but the whole gun is a little long in the stock for me. Rather than exchange it for the MKII receiver (check the CAVarms forum for details), I've decided to sell it as I already have too many AR's.
It comes just like you see it. No accessories, but I'll throw in a mag.

Sorry about the sideways pic
