Most Helpful Positive Review Great product!
THIS stock really exceeded my expectations. I would recommend this for any build. It's cheap yet very durable. the rubber check pad is a really good quality rubber and dosnt pull your skin. AND the finish is very nice as well.
Most Helpful Negative Review Cheap kit, for a reason.
It's ok for a real cheap budget build. The inside of the buffer tubes are really rough on the three I bought. The rest is decent for the money. There are probably better kits out there for just a little more money.

Poor product and customer service

by Slim, from OK, United States Written on January 8, 2020
I purchased one of these kits fora 458 Socom build. After little use and no abuse, the stock broke at the latch. When I contacted the company for a replacement, I was told it would be a minimum of two months for replacement. I would stay away from this stock, there are better products available at the same price point.

Nice stock for the price.

by Alan, from IL, United States Written on August 15, 2019
As the title says, this is a nice stock for the money. It's a comfortable, good looking price with all necessary hardware included. Great piece for my budget build. That said, it has some play between the stock and buffer tube. Less than the GI M4's I've dealt with, but if you want tight, you'll have to do some tinkering. The inside finish of the tube is rough, and makes for noisy charging, but works fine. The castle nut is not notched for staking, of that matters to you. None of this matters to me, but may matter for your build.
Pros:
  • Cost, functionality, looks.
Cons:
  • Finish
Best Used for:
  • Low to mid budget build
Would recommend: Yes

Fantastic Value

by Johnathan Faith, from KY, United States Written on May 9, 2019
The stock fits, works as described, and is cheap! I'm using this setup on a 7.62x39 rifle. So far, the buffer has held, but be advised that it is a cheap, Chinese buffer. Even with the buffer considered, this setup is well worth the cost.
Pros:
  • Cheap, fits well
Cons:
  • Included buffer
Would recommend: Yes

great stock

by Kevin Swigert, from ID, United States Written on May 3, 2019
I had been researching the parts for a .224 Valkyrie build and had came across the Trinity Force products. The price was very reasonable so I took a chance and ordered this kit. Worst case I would use it on some other knock around gun. I could not be more pleased with a the stock and the buffer tube parts. They are all built with quality and attention to usable detail. I especially like the molded rubber check weld, much like Hogue products. I have definitely found my new favorite stock setup, if you are working on a budget you can save real money on this and not cut any corners.
Pros:
  • design, materials, workmanship
Cons:
  • color is slightly different than most fde
Best Used for:
  • mid to low budget builds
Would recommend: Yes

Ok butt stock

by Tripp, from WV, United States Written on April 28, 2019
Ok butt stock installed easy. Nicely made has a little bit of wobble. Color matches what it is. Fast shipping had no problems! If you have extra money look for one that is better made. Price of what you pay for is how well it’s made!
Pros:
  • Price
Cons:
  • Little wobbly
Best Used for:
  • AR platfrorm 15
Would recommend: Yes

Nice for the price!

by Ksarles, from TX, United States Written on January 22, 2019
I ordered this to save some money hoping it wasn’t one of those “you get what you pay for” items, well it’s really solid and at a great price! I received it in a timely manner as well. Haven’t had a chance to put it on my rifles since I’m waiting on my MDT ESS chassis. Can’t weight!

Nice kit, stock is better than the "Mil Spec" that came on rifle

by DWY, from WA, United States Written on January 8, 2019
All fits perfectly, the indent on the buffer tube makes
matching to the buffer detent pin easy and precise. Spring
looks to be good quality and detent slides easy. I like the
configuration of the stock as well.
Would recommend: Yes

New AR Stock Kit

by Todd, from UT, United States Written on December 23, 2018
I like the new stock kit very much. I have not had a chance to shoot with it yet, but installation was easy and it fits and works better than the original one did. The rubber on this stock is much nicer and heavier than the original, and feels much better to me. I bought two of them and will be installing the other one soon.
Pros:
  • Better recoil pad by far
Cons:
  • None
Best Used for:
  • Plinking , or self defense
  • Plinking, or self defense

Worth Every Penny

by RAMjetta, Verified Owner from VA, United States Written on August 26, 2018
This really is a well made budget friendly Butt stock. The only reason I've only given it 3 stars is because I haven't gotten to the range yet. Originally purchased for a 5.56/.223 build but decided to build a .300 Blackout. I will update after putting some rounds down range. I will be buying more.
Pros:
  • budget friendly
  • Well constructed
  • Feels and looks great
Cons:
  • None
Would recommend: Yes
