Traditional look with modern features by JamesT, November 14, 2023
Always preferred the triangle stock on my WASR, but was tired of having to rig up a cheek rest. Got the additional buttpad and cheek mount, and I can enjoy all of the traditional look while making my rifle more comfortable to shoot.

Nice stock, quality miss by Yooper78, Verified Owner, January 26, 2025
Stock had a bad paint touch-up that didn't match the anodize. It should have been sold as a blem. Otherwise, with the addition of the rubber buttstock and riser, I like the stock. Mounted to ADM UIC 180 lower.
