Great Product


Always love the value from Primary Arms!



Can't beat the price.

not too bad, could be better


Easy installation for my first AR build. Never thought it would rattle so much. I guess as long as I'm not hunting it's ok since I don't need to be quiet. If i built another AR, I'd spend more on one that brags its fit.

DS Arms Mil-Spec Stock Hardware Kit


Excellent no-frills stock with all of the hardware you need for installation. Installation on Anderson lower was easy and fit was good. Recommended if you are looking for a solid entry level stock.

stock kit


fix is great everything i have purchase from primary arms has been excellent.

Great Butt-Stock Assembly


Had ordered a butt-stock assembly from another source & paid about $18 more! The stock was wobbly when slid onto the buffer tube so I contacted the distributor & had to wait & wait & wait for a reply.In the mean time I saw these stocks listed on PA so I ordered three, they arrived in record time & the fit is like a hand sliding into a glove! As soon as these become available again, I will order more! I would also like to mention that in addition to the butt stock assemblies PA included a CRKT knife & tool combo which really surprised me! These items are not cheap pieces of Chinese junk, especially the knife!



I am very pleased with the service an care givven to my purchase and will recomend to others to consider their next purchase with primary arms.

Excellent product


I cannot get over how fast Primary Arms ships their product when ordered, and shipping is NO way over priced like so many other vendors are charging.Primary Arms will have my business for along time!Thank You!!

"Well made - Great value - Enough said"


I was collecting parts on a "budget" when I saw this kit. The fitment was perfect. And the 6 position stock actually works more smoothly than a major name brand that I own. And getting all the items together saved me cash!! You can definitely buy a better buffer & spring, but this works great!



It look great!
