Tim's Review of Maxim Defense Industries CQB Buffer & Spring Set
300 blk AR pistol with 10.5” barrel (pistol length gas system) would not cycle subsonic without a suppressor attached. Replaced original Maxim standard buffer/spring combo with H3 buffer/spring and problem solved. The original spring was shorter and stiffer. The spring with the H3 is longer by about 3/4” but compresses easier, allows more travel. Now it runs well suppressed or unsuppressed.
