Most Helpful Positive Review Compact, simple, lightweight AR stock
The more Leapers products I get, the more I like them - reasonable prices, good quality (good enough for me), and innovative designs. Their S4 stock is my most recent purchase from Leapers, and it embodies all the things just described about Leapers. This stock is ideal for me, but might not be for you. I like how compact it is, but the smaller interface with your shoulder may or may not be ok for you. The cheek "riser" doesn't really do much to raise your cheek, but it does provide an extended stable surface for your cheek weld (to mitigate contact between cheek and buffer tube). BUT, de...

Great Quality

by GusDBus, Verified Owner from CA, United States Written on February 8, 2026
For what the stock looks like it gives off, ARP brace. It’s solid, easy to install and comfortable. I would recommend.

Perfect Fit

by JayS, Verified Owner from TX, United States Written on August 24, 2025
The stock is lightweight and it fits a little tighter than other big name brands stocks. Don't expect too much adjustments because this minimalist design only mounts to the last few adjustment points.

shave off alot of material

by Sylvestre Palacios, Verified Owner from MP, United States Written on October 2, 2024
Upon installation I have notice that the charging handle will bind with the cheek piece causing the charging handle to bend. The only way for it to really function properly I had to shave off a lot of plastic which made the butt stock look worn down

Perfect Lightweight Option

by KM, Verified Owner from MA, United States Written on June 21, 2024
Perfect Lightweight Option for an AR10. I removed the cheek riser on mine and my gun is so lightweight when weight reduction is a must. Combine it with a strike industry stock stop and jb weld for a light fixed stock option on a mil spec buffer tube

WAY BETTER than the standard default ar15 stock

by sam, Verified Owner from NC, United States Written on May 11, 2024
My god, this is a huge improvement on the default stock my psa ar15 had. It is comfortable to shoulder, and super lightweight. Apparently there is a battery compartment but i havent found it yet.

Installing it was slightly finnicky, and even still when im adjusting the position it likes to wobble a bit. But just finnesing it gets it to stay in place.

Overall if you want a cheap lightweight upgrade, which is also comfortable, get this

Quality over price

by Dingleblaster, Verified Owner from MA, United States Written on February 20, 2024
I was a bit worried about the quality of the product because of how cheap the price was but it was more solid than my magpul moe stock. Definitely comfortable and worth every penny.

Great For a .22 & Ar-15 with Mil-spec buffers.

by JAS, Verified Owner from FL, United States Written on December 2, 2020
Awesome little stock for the money really compact and light weight for the money.
Great for my 22 since recoil isn't hard at all. Could be great fit for any AR-15 as well. Tried on my AR-10 but would like a little more padding for that one.
Highly recommend for light recoil calibers that you would like to keep minimalistic and compact.
Pros:
  • Compact & light
Cons:
  • cheek rest could be a little higher
Best Used for:
  • low recoil calibers.
Would recommend: Yes
