    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

    Moving on up

    The UTG stock assembly I purchased is top quality, designed well and functions like the other brand name stocks I own. I have been watching this company produce better and better quality products that I consider top of the line. I have to give them credit for stepping up to the plate in their product improvement and innovative design. I also like the fact UTG is making more products in the USA than in the past. No longer a 2nd tier supplier.

    Thank you for the input, Kent! We appreciate the detail
