My wife bought me this kit as a birthday gift, (stars and stripes) it was my first build and I was very impressed with the kit. Everything went together well and it looks great.
The gun fires flawlessly. I have had no issues at all.
I plan to build a few more in the future. Thank you outdoor sports USA. Daniel R. New Mexico

This was my first build and I loved it!! I wasn't sure I did everything right since the trigger kept sticking but once I greased it properly everything worked smooth as butter! Finally got to shoot it a few days ago. It's my new favorite gun!! I absolutely love it!

-Good learning experience
-Easy upgrade to .300 BLK (just need a new barrel and flash suppressor)
-Buffer tube spring is tight

-Non mil-spec (don't scratch that jam nut!)
-223/556 is not meant for 7.5" barrels.
-Chinese made kit shipped out of California... lol

-Ordered 12/07, shipped 12/13, arrived 12/19

I've ordered multiple kits from outdoor sports USA. You definitely can't beat the price. I haven't had any issues yet. All orders came in a timely fashion. Usually 3-4 days. And Everytime they throw in extras. This is how you take care of loyal customers. I'll be ordering again soon. Thanks outdoor sports USA. Ron S. Texas

The kit itself, for the price, is not bad. Though a good number of parts were obviously aftermarket Chinese grade stuff. Both the barrel nut and sights were Airsoft parts, the barrel nut actually snapped in half when I attempted to put it on. It doesn't fit a standard barrel nut wrench so I had to improvise with two screwdrivers. It was made vary cheap aluminum and broke far to easily. All and all expect to get what you pay for in this kit.
