Great ar lower parts kit

All the parts are Excellent and fit perfect


"Top Notch Quality, Reliable Service"

"I ordered several things from this company, and this was the first to arrive. The buttstock and buffer tube, and the lower parts kit arrived when expected, and they are high quality. The buttstock is well made, and operates smoothly. Buffer tube high quality, and lower parts kit is complete and appears to be mil-spec. Thanks, guys."


Good kit for a basic build

"Anderson Mfg makes mil-spec parts. Not fancy, not target competition, just plain working parts. They fit most mil-spec receivers (at least all the ones I have, since they're usually my choice in lpk's), and again, they're plain-Jane, working parts. They'll probably outlast your grandkids with regular use and care. I'd recommend this kit to anyone, as it's at the best price point for all the parts I've found anywhere."
