Quality is great, I ordered from another .com and was very poor quality, Have learned from that mistake and will stick with 80% going forward. Thank you guys keep it up.
I was really impressed with the quality of the machining of the machined lower. I have a small machine shop in my workshop so I decided to make my own jigs for the lower to mount either on the table or in the milling vise. The only thing I wish 80% Lowers would include would be detailed assembly instructions. I was able to find those eventually on the internet, but for a first time builder it can be tough to know if you are actually getting good info. Info on manually machining a lower would be helpful too. Mark
What a deal!
I spent an afternoon on this and the entire experience was a great one. First of all the price was amazing for an entire rifle. And second it went quicker than I thought it would. I went with 300 BLK because I have a couple ARs already and none of them are in this caliber. Overall I'm very impressed with this kit!
Very affordable and had a blast building!
What a great deal! It's awesome that I got a full build with this kit and it was super affordable for the experience of building my rifle myself. The process was a ton of fun, and now I have a sweet AR15.
Trying a new caliber
I've never messed with the 300BO caliber before, so I wanted something I could do myself for my first one. This kit was helpful to me. First of all it was a great price for a whole build kit. Second, when I was done this kit ended up giving me a pretty solid rifle. I'm very happy with the end result!
