Lower parts kit
I was able to complete my retro CAR15 build wih this kit.
USPerfect to get you started
So far so good all the parts went in without any issues. If you have a stock laying around this is the perfect kit for that. Bonus that it has a QD spot under the castle nut.
United StatesBare bones
With a name like bare bones, you can’t expect “high end” parts. You can, but you are going to be disappointed. I didn’t expect anything other than what it is and I am satisfied with the kit. No issues with installation. No issues with shooting.
United Statescombo
i bought this when it was on sale for 50 bucks. trigger is good. slightly better than standard mil-spec. buffer tube is built incorrectly. when you screw it in to properly seat the detent, it becomes over screwed and the upper doesnt want to close down all the way. i had to then remove and use a bastard file to remove about 1 to 1.5 threads to get it to fit properly. didnt take long with a good file. just have to hold it flat and file with a steady hand. otherwise your only other option is to have the lips on the buffer tube barely touching the detent. and i mean barely. never had that problem before with any other buffer only this one. but because it was such a good deal and i do build guns and dont mind a "challenge" id but it again, if it were on sale for 50 bucks. but i wouldnt pay almost 80 for it. other places have similar deals for around 60 to 65. so i recommend it when its on sale.
