2 AR-15 bolt carriers. Both have had less than 300 rounds through them. They both have proper staking and had no issues with either one. I upgraded mine to nickel boron and these are spare parts to me now.. Also have the bullets for trade over in the reloading section of the board. Flat top iron sight set. Front flips down. Front sight is setup for gas block mount. Also have a dpms front gas block sight. As new. Pulled off barrel before fired first shot. Odds and ends barrel nuts. Pistol hand guard goes with far right nut. Threads (in one spot) need some attention, but still serviceable and quite useable. You can somewhat see it in the picture. As far as trades go, I'm looking for other AR stuff, remington 700 short action stuff, cz-75 stuff, and savage 93 stuff. The calibers I load for are .223, 22-250, 9mm, 25-06. In case you are looking to trade off reloading gear/supplies. Shoot me with a pm with what you've got.
