I know it is a Bushmaster (it came off a complete Bushmaster rifle that I purchased new many years ago) and it's a 14.5" with muzzle device (not sure what type it's classified as) that is permanently affixed and brings it to 16". I'm not sure what the markings on the barrel mean (besides the twist rate). Not sure if it's chrome lined, how can I tell? I know it does not have M4 feed ramp cuts. I qould like to list it on the EE and want to be able to give an accurate description. Any estimates on a value with bolt and charging handle? The rifle has minimal use, I would guesstimate it to have less than 500 rounds total through it (I know, I know, Shameful! But it's one of seven and the others are well used :) Any help identifying this upper is greatly appreciated.
Thank you!

It's a Mini-Y comp. I have the same model, and it's a loud one.

Looks like a post-ban M-4 upper with a perm Mini-Y comp.  5.56 chamber with a 1/9 twist.





Look at the chamber opening to tell if it's chromed. If it's silver looking in there, it's chromed.

As stated, the muzzle device is a Y-compensator and it is pinned on in two places. They work o.k. but will blow the shooter next to you off his/her feet. The barrel is a Bushmaster Magnetic Particle inspected 1/9 twist and it is chrome lined. This was off a "post-ban" gun so no bayo lug. It is a good shooter but everybody wants 1/7, bayo lugs and M4 feed ramps today. Even the A2 is out of style with more people moving to the simple is better A1 uppers. You can get a complete bushmaster for about $600, I think you would be lucky to get $150-$200 for the upper with BCG.

Keep it and shoot it.

Thank you all for your input. Sounds like the "keep it and shoot it" advice is gonna be the way to go.
