Excellent lower
This was my first build, so I did tons of research and wound up selecting the Anderson kit with stainless trigger. Putting it together was much simpler than I expected and cycling all the controls everything smoother out. I put a BCA 50 Beowulf upper on it as shot it today. The trigger was very good – better than a Colt and Armalite that I have. Everything functioned flawlessly. Greatly pleased with Anderson.

AR 15 80% Build Kit
The items included in this build kit were impressive to say the least the quality and performance of this Kit after I built it was totally awesome. I feel that this build could compare to any other AR-15 manufactured by any of the big names ex. Bushmaster I would recommend this kit to anyone who is thinking about building their own 80% AR15 and I look forward to doing business in the future with you company

First Build
Got the stainless trigger build to use on a Anderson Lower and it went together like it’s supposed to. I was surprised how easy it was.

Great Product
I used this kit for my 1st build. I have an Anderson lower and I figured why not use an Anderson built kit! So, I placed my order and I do not regret my decision. I was surprised by its stainless trigger and hammer assembly. Once I built the lower I tested it and wow, it is crisp. Almost like a piece of glass breaking when it releases, and it has little to no travel/slop. If you are on the fence on this kit, don’t be. I will order this kit again for my AR Pistol build for sure.

Lower parts kit.
Everything fit together perfectly. The only issue is the trigger pull is quite hard but nothing that couldn’t be dealt with.

Great product
Overall this was a great build kit for my first build. I like the stainless steel trigger/hammer, but the finish was a little too matte for me. The box it came in was pretty rough and was missing the rear takedown pin retention detent, but for the price it functions perfectly

Lower build kit
Over all I’m pretty satisfied with the build. Everything went to get her with my Anderson lower. The only down side was the stock seemed shorter. The rifle is not complete but the parts feel good with quality.
