Smooth Transaction


Package arrived in minimal time with no issues. Haven't had time to finalize assembly yet but it's coming. Thanks folks for a smooth transaction and prompt delivery that was well-packaged.

Stay away


The kit came quick from primary arms so great job to them. However, I feel like this kit comes with a few parts that you don't need if you have a spikes 308 lower. For example, it comes with a finger guard and the bolt release. Also I question the qc because the L shaped piece of the mag release was to long. This meant the mag release button couldn't screw down far enough to make it where the L piece wouldn't just spin around.

Spike's 308 LRPK


No hammer no trigger no pivot pin no take down pin a trigger guard that you can't use on a Spike's 308....so basically you are paying $63 for a magazine lever bolt hold open and selector. Not much of a lower receiver parts kit especially for $63 !

It works I guess


Pay attention to the verbiage. This kit doesn't include the take down pins. Why would you even make a LPK without them? Also the Magazine release assembly didn't work well that came with this kit. Luckily I had another lying around. The shipping from Primary Arms was quick but I would go with one of there other LPKs if I were to do it again.

Contained wrong parts

Didn't notice that it doesn't include takedown and pivot pins. Also, the grip wasn't the right size, and the bolt catch and pin were for an AR-15. Don't waste your time, or money.
