Ratings & Reviews
THE SPIKES LPK WAS EXCELLENT THE PRIMARY ARMS BUYING EXPERIENCE WAS AS GOOD AS IT GETS, I GIVE SPIKES AND PRIMARY ARMS 5 STARS
Better than average.
by Daniel Bayley
A little bit nicer trigger pull than the cheaper lower parts kits. Everything else is par for the course. I'd buy again.
high quality LPK
by Jack B.
After 6 builds with different LPK's I can honestly say it's the little things that matter. Spikes kit delivers consistently mil spec products that fit and perform well
Nice Lower Parts Kit
by R. Parks
All parts fit well, even the A2 grip was okay.Primary Arms is very fast in getting a order out.
All the parts went together easily. The trigger actually feels pretty good. I had to watch a YouTube video to make sure I had the right springs and pins in the right place. There's even an extra pivot pin and spring.
Great parts at a great price

As usual, if it's in stock I'm buying it from Primary Arms.
Spikes Lower parts kits and Spikes upper
by Sonny Ramos
Awesome product. The shipping is fast. Staffs are very helpful. Primary Arms has a wide selections of excellent products. I would recommend their online store.
Great Quality and Price
Bought this to match my Spikes lower, fits great!! Nice trigger pull, and tight, high-quality parts
good quality kit
did my 2nd build using this kit...parts seemed quality enough, although the trigger pull, while very crisp and creep-free, ended up way too heavy for my tastes. my 1st build I used a DPMS kit, and the trigger pull on it was outstanding by comparison, and that kit is cheaper
by Jeremy Hess
Easily worth the extra 10 or 20 bucks versus less expensive LPKs. The fit and finish of the parts is second to none. Comes with some extra springs and detent pins. Trigger pull is a crisp amd breaks easy, I will buy this LPK again for future builds.

FIT AND MATERIALS ARE EXCELLENT !
Great Parts Kit for the Money!
by Brandon Price
Fit nicely into my Anderson lower. No problems with install or missing parts. Trigger feels pretty good, but of course it is not a custom.
Just as expected
Good fit and finish on the parts kit, both fit perfectly into a pair of lowers for which they were ordered.

Good useful kit at great price
Bad bolt catch.
Great basic lower parts kit. Unfortunately the kit I had contained a bolt catch that was machined way to thick. I ended up just ordering a new catch. The kit overall seems alright. PA was great to deal with. They're my favorite site to conduct business with.
