Michael Hanig –
Could really use some instructions
Ronald Goodrich –
I haven’t had a chance to use this kit yet, but based on the quality, I’m looking forward to using it.
Edward –
I just started building AR rifles and this was the best kit I could find for the price. After building two AR’s and testing the rifles, they functioned perfectly. Im ordering a few more kits to build more guns and to use for parts. I’m sure as I learn more about the process and function of the AR platform, l will replace some of the parts with higher quality, more expensive parts. The only parts that I find to be questionable are the butt stock and pistol grip.
Bill Swires –
Everything went smoothly all parts fit and worked correctly. Couldn’t ask for a better price or quality.
Scott Miller –
