I’ve had a number of Colt 9mm AR15s in both pre-ban and post-ban configurations and I even used the Colt smg professionally. Colt is one of the finest manufacturers of AR15 products in the world. While others have faltered, Colt’s steadfast quality hasn’t. This lower is no different. I had the upper on a CMMG Mk9 lower and it I wanted all Colt, and this lower fits the build with a Daniel Defense butt-stock and pistol grip trigger guard unit

Bough complete Colt Lower. Great fit brand new as described. First time buyer here, buy with confidence. Fast shipping.

If you're iffy on the paint job it's a hydro dip and seems pretty tough. The colors look better than the picture, more matte. Everything else is all Colt, nuff said.

Colt made very few, fit and finish were flawless

This is the third receiver I have purchased from Arms Unlimited and like the previous two (m4,m4 piston) I have been fully satisfied .Unlike some others that have gotten theirs with blemishes mine have been in as new condition...I will continue to order from them in the future as my needs arise.

Sharp looking camouflage but it is a little thick in some places. However lock up is tight with zero wiggle. Can't go wrong with a Colt especially a 9mm at this price point.

Everything was smooth and the combo set looks great

Very tight lock. Is an AR with a block in mag well. Great job made by Colt. Trigger good quality but needs A trigger job Can beat the deal for 300. Buffer top quality. Buy it

Bought 6 of these, they all had some degree of handling marks in finish, so expect it, you will not be shocked. Assembled and shot one at a 3 gun in Muncie Pa. the carbine cycled flawless with a ramped Colt bolt and 32rd Colt mags. We are very pleased with out purchase. K & R Gillett Pa
