Finished her off nicely

Part was perfect fit, I like the flat finish, and black hardware which matches the theme. The lever lock is much better than other stocks ive seen, positioned and shaped nicely. Instructions included are very helpful, and lucid. AT3 provided very prompt service, despite being 1000's miles away, i received my merchandise in a few days!

That looks perfect! Thank you for the great review, Carl.We really appreciate you taking the time out to share your experience with us—and we agree, UTG PRO S3 Mil-Spec Buttstock Kit is truly great! - AB

Good kit

All the parts were certainly of good quality and worked perfectly. The only exception was the buttock itself. The release lever for the slide feels pretty flimsy and wobbly. The buttock itself was a four position stock on a six position tube and was a bit shorter than I was expecting.
