I have a used but in great working condition Factory Bushmaster M4A3 Patrolman's Carbine upper with 1:9 barrel. Comes complete to include BCG and CH. Upper has some dings and rub marks here and there but functions perfectly. Barrel is newer and has less then 1k rounds through it. Selling because I purchased a lightweight BCM upper instead. Looking for $400 in the Tigard area. No trades and email direct at firstname.lastname@example.org.
