    "Put them in one of my m4's with a 13/1 super speed gear set and shimmed it perfectly. Semi auto sounded fine but fully auto started grinding about 100 shots in. I saw a shim fly out the barrel so I knew something was wrong. Opened it back up and one of the bearings exploded inside the gun. One of the metal balls in the bearing just flew out and through everything out of wack. I bought them knowing this could happen from reviews I had seen and surely it did. I would not recommend these, atleast for a high speed set up. They can't handle it. Love matrix, hate these bearings.

    "These bearings are great. I installed them into my high speed echo 1 g36 which i had origionally tried to install matrix solid bushings, which didnt fit level with the GB. So, I bought these and I am very pleased. They not only fit perfectly in the GB, but with perfect shimjob i get 23 revolutions out of one spin with all 3 gears installed. Before i was only getting 5 with bearing bushings.

    -Fit level with GB
    -Slightly over 8mm to compensate for wear
    -Great preformance and build quality
    -increase ROF and makes GB sound smoother
    -Withstand 33rps and 360fps setup


    All in all this is a great product especially for the price.

    "Very very happy with this product. They fit tightly in the g&g GB I put them in. The quality seams very good. They spin very well, reduce an enormous amount of friction. Up the performance of the aeg. Price is excellent. I don't think you could get a better deal for $15.
