Colt A2 upper marked C MB. 20'' Gov profile barrel marked C MP 5.56 NATO 1/7. A2 flash hider FSB marked N R1 (in small circle) 3, No bayo lug. Couple of small scratches on shell deflector, where the charging handle latch rests and also looks like previous owner tried to mount a scope base. Overall very nice. Previous owner told me round count of 1000 to 1500, I put maybe 150 through it. I am parting with it because I am not as into shooting a 20'' as I thought I would be. I will try to get some pics upon request. SPF shipped. E-mail questions to firstname.lastname@example.org.
