Some team members use the TIPPMANN A5 NLTM-FD modeled after the awesome H&K MP5 A3, the real weapon is a 30 round, 9mm, 600 rounds per minute, 4.6lb semi, 2 round burst, & fully automatic tactical weapon. Our customized weapon is the same size, weight, magazine capacity & firing rate, but shoots our 68 caliber NLTM. Reliability is maintained with the addition of the A5 Vortex Mod from Techt Products.
