I couldn't be more pleased with my purchase. Got exactly what was advertised at a really great price!

My gun that I purchased was ready to shoot right out of the box. I added a couple accessories to it and now it's up to my requirements for this type of firearm. I've had it a short time but have already run some ammo thru it. Performed flawlessly. I only need one but have recommended it to some of my friends. They wont be disappointed.

It's a Colt, what else to say!

I have always wanted a Colt M4, but could not find one. Ran across these for a very good price! My dealer says he could not touch the price I paid. I am a happy camper! Let's Go Brandon!

Colt 6920 M4 carbine 556 NATO

The Gun is very well made as well as balanced in your arms. Colt or CZ did an outstanding job on the manufacture of this firearm, all features of this CR6920 are spot on requiring no tweaking or adjustments. It fires flawlessly with predictable results - No Surprises or Battlefield repairs or adjustments required. I would recommend this purchase as well as using GUNPRIME to all friends and family as the Gun arrived promptly with no damage or broken parts. kudos goes out to Gunprime your prompt execution and shipping of the Firearm without any external damage to the cardboard boxing.

Great shooter

This is my first Colt rifle and it does not disappoint. I’ve put about 100 rounds through it and have had zero issues. Shoots and feels great. I replaced the included rear sight with a Colt carry handle and A2 sight. Being a left handed shooter, I also replaced the charging handle with an ambi and installed a BAD lever on it. No plans to do anything else. Was very easy to zero and I’m very happy with my purchase. GunPrime was great as always. Fastest shipping ever. They never disappoint.

Easy and Fast

Haven’t had a chance to run it yet but came in great shape just as advertised. Shipping was super fast and they had my FFL on file which made it a breeze to order.
