Questions & Answers
Is the barrel cold hammer forged or button rifled? Expert Answer

It is a chrome lined M4 contour barrel.

Can you fire 223 Remington ammo with this upper or just 5.56? Expert Answer

The Colt Mfg LE6920CK Upper Receiver Conversion Kit is chambered in 5.56 NATO, which means you can safely shoot both 5.56 and .223 through this upper.

I recently got this kit. It fits nice and tight in my Aero Precision lower. It came with charging handle, BCG and sights. Takedown pins came with complete lower. This kit is plug n play. I got with 14% coupon.
