GL-Core Buttstock

Installed on a commercial buffer tube. Fit very snug, added a small amount of lube and worked a dozen times and now it now works quite well. Love the configuration of the stock.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Awesome

This stock is comfy has nice tight fit and has much softer pad than most stocks in this range. Perfect AR15 platform stock. If using on a commercial stock make sure the inserts are 100% lined up in the grooves

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
