Building AR-10’s can be just as fun as the smaller AR-15 and there are large amounts of aftermarket parts as well. The AR-10 platform is extremely similar in terms of assembly and function and some parts are even interchangeable; it is just scaled up to withstand the power of the .308 caliber. This lower parts kit from Luth-AR comes with everything you need to complete your lower receiver except the fire control group and pistol grip so you can customize your rifle how you want. Pick up this affordable LPK to finish building your AR10 lower receiver and know that you are receiving quality parts to help your gun run reliably.

Good deal!

I had been considering giving this kit a try for awhile, When I saw it was on sale I decided it was time. Thanks PA!

Don't expect the parts to arrive in a nice, fancy vacuum formed and labeled package like you see on the Luth AR website. The parts package I received was a small, resealable plastic parts bag. That's not an issue though. After inventorying it, all the parts seems to be their so I'm happy. I'll come back and post an update if I discover any issues on fit or quality.

Bolt catch hits the upper receiver

by -

This might be a compatibility issue with the palmetto ar10 6.5 creed upper and lower. but the bolt catch hits the upper receiver preventing it from lifting high enough to do its job. All other parts in the kit seem fine and mine showed up in a plastic hard case not a baggie.
