450 Bushmaster 10.5" complete AR15 upper made by BCA. 

Better than new!
From the factory, the upper was under-gassed. The problem has been fixed and it runs 100%. (Don't forget, it comes with an excellent warranty).

I added a $50 Kaw Valley linear compensator to reduce muzzle blast and noise for hunting purposes, and lightly polished the feed ramp to a shine.

Will come with a CPD stainless 5rd 450 magazine ($25) , 20rds of Hornady Black 250gr ammo ($20), and a Sig Romeo 5 red dot, perfectly sighted in at 100 yards.
Can sell without the red dot if you wish.

Functions great! Perfect deer or hog thumper! 

I still have the box and paperwork.

Will consider including the complete lower receiver for the right price or trade.
