Frequently bought together:


The Alpha Stock is versatile enough to work with any AR build. It features a low profile adjustment latch, double injected rubber check rest, and slick sided profile. The butted profile is angled to accommodate plate carriers and the aggressive texturing will ensure minimal movement when manipulating the rifle under stress.

The stock kit comes with everything you need to get your rifle up and running including a steel endplate, castle nut, buffer, buffer spring, and a Mil-Spec anodized aluminum buffer tube. The lightweight construction will ensure that your rifle stays agile and the stock’s ergonomics will augment comfort and efficiency while shooting.


For your safety, Trinity Force recommends this part be installed by a competent, qualified gunsmith/installer with an understanding of the weapon platform that the part is being installed on. Always make sure the firearm is unloaded and pointed in a safe direction when working.

    Stock wont collapse on the buffer tube

    Posted by Nick on Dec 23rd 2019

    Ordered this stock kit, the stock is wobbly at the 6 position and it cannot even make it to the collapsed position cause it's too tight. Can not recommend this.

    I've been using the Omega stock for a few build, but I really like the Alpha as well, and at a nice price point also!

    Very nice stock. I do not like the end plate or casle nut. They seem to be of inferior quality.

    For the money, you can't beat this deal! Just what I needed to complete my build. Comes with everything you need to finish out your rifle. Stock has plenty of options for sling mount points. Nothing fancy, no frills just a great all around kit for those building on a budget. Will be ordering more, highly recommend!

    One of my favorite stocks, and buffer tube is super smooth on the inside, no problems with installation
