Wrong, a .22 caliber weapon shoots a minimum of 1,000 FPS, no lie.
.22 long rifle hauls ass at 1,038 ft/s (316 m/s)
9mm, depending on granule, weight/density of the bullet, averages 1,300 ft/s
additionally, the 5.56 NATO hits around 3,000 ft/s+
Think I should put this on my M14, if I plan on being a designated marksman?
Uh, that's just a tan casing and an extremely cheap vertigrip (the exact same one came with my Double Eagle G36c [a $50 gun package])
