This rifle is ready to go as is. Here we have a pre-ban Colt lower (small pin), keyhole-forged upper, with the following features:

-Giessele Trigger (specific to Colt lowers) 

-Maritime bolt catch

-1-8 twist new barrel- 20 rounds through it

-Aero Prescision Mlock 13 inch handguard

-QD ready end plate

-CTR Magpull collapsible stock 

-Wilson Combat flash hider

The sear block was milled properly by a professional gunsmith.

The rifle comes with flip-up sights, a 30 round pre-ban mag, and a generic red-dot optic. 

The trigger in this rifle is close to 300 bucks.

This is a steal at 2400 with a pre-ban, 30 round magazine.
