Excellent All-In-One Kit
I wanted a complete, no-fuss solution for my AR-15 build, and this kit is spot on. The UTG PRO, FDE Mil-spec Stock Kit includes everything you need—buffer, tube, castle nut—all Mil-spec. The minimal profile and 4-position adjustability are huge pluses. Highly recommended!
-
Decent But Could Be More Comfortable
The stock is lightweight and has a nice FDE finish, but I found the cheek rest a bit short for my setup. It’s still decent for the price, but if you prefer a taller cheek weld, you might consider alternative options. Installation was smooth, and everything else seems solid.

Perfect for Plate Carrier Use
I wear a plate carrier a lot, and the UTG PRO, FDE Mil-spec Stock Kit gives me the shorter length of pull I need. The locking positions are precise, and the sling swivel housing is easy to swap. Cobratac made the buying process hassle-free. Two thumbs up.
-
Excellent Feel & Quality
I love the rubberized butt pad—it makes a noticeable difference in recoil control. The cheek rest is great, especially with the removable extension for added comfort. It’s my first UTG stock, and I’m impressed by its sturdy build.

Great Fit for My SBR
I needed a compact stock for my SBR project, and this FDE kit delivered. It’s comfortable, adjusts easily, and locks tight. Cobratac shipped it out quick, which was a plus. Highly recommend for anyone looking to minimize bulk without sacrificing quality.

Solid Stock, Some Installation Hiccups
The UTG PRO, FDE Mil-spec Stock Kit is well-made and surprisingly lightweight. Installation took a little longer than expected, but once it was on, it felt rock solid. I wish it had clearer instructions, but overall, it’s a great addition to my build.
