    It also works great in my LR308 DPMS Gen1. So simple yet so effective.

    They do exactly what they were made to do. Takes out all play between upper and lower receivers. Definitely worth the money.

    Works great! Got a new upper and lower from the same company that didn't fit tight. Accu-Wedge fixed that. All I did was put it in. Super happy!

    Got a new upper and lower from the same company. No brainer right? They should fit together tight right? Not!! This product saved my build, for sure! Love it!! My new upper and lower fit perfectly now. If you are planning a build, just get a few. It's a no brainer.

    A+ part. These are soft and pliable. I bought some other brand (UTG) and those were very stiff, would not compress properly. These fit properly and compress like they should. This was my first time buying from AU and I would definitely give them an A+ rating. Super fast shipping, had my items in about 3 days, all items were as advertised, super smooth transaction with AU. Buy with confidence.

    Definitely Help giving you that Secured Feeling with out the Wiggle. Though have to cut to adjust the fit between the upper & Lower. I would strongly recommend buying more that 1. Great Price as well!
