Kit was purchased new and unopened, installed complete on a standard AR lower with 9mm magwell adapter. Kaw Valley Precision 14.7oz. 9mm bolt. Tested with 2.5" and 5.5" barrels. American Eagle 115gr. 9mm. Video shows 10 selected video captures of bolt bounce from the EPC buffer kit. 33 video captures were taken in total. Of the 33, seven captures did not record noticable bounce. That would be about a 79% bounce rate, or about 4 out of every 5 shots. More information can be found at Blowback9.com.
