Great bargain. My first AR build.
Had a great time building this AR pistol. I've owned AR's, but I've never built one. This is also my first 300 Blackout. Fun to shoot. Works flawlessly. I've shot both subsonic and supersonic ammo with no issues.

Great build kit
Bought this kit to assemble into a pistol. The build kit is superb. Not just a bag full of parts. Each spring, plunger and associated part were in separate bags. Built on my lower with no troubles. The upper assembly was perfect and matches the lower great.

Perfect for a first AR assembly
This turned out great. My first AR assembly, everything fit together well. Took about 30 minutes for the build, and after it just made me want to do another. Took it out to the range and everything operated without faults and very enjoyable to shot.

Fun shooter and it works well.
For my first AR pistol build, I couldn't be happier. Easy to assemble and it functions well. Havent shot a lot through it but from what I have shot it's great. Time to sight it in and get ready for deer season.
First 300 BLK and it functions correctly. I'm happy with it.
