The Maker REX bullets are precision cnc machined, lead free, solid copper expanding projectiles. REX projectiles expand to nearly 3 times the original diameter while maintaining nearly 100% of its original weight. Each REX projectile has been engineered to perform in a given velocity range to provide unparalleled performance across a wide variety of calibers and weapons platforms
As with all subs, proper cycling requires the use of a pistol length gas system for all barrel lengths. If using a suppressor, test the rounds at 10-20 ft without the suppressor to ensure the bullet stabilizes prior to using it with your can. If "keyholing" occurs, do not use with your can or damage will likely happen. A barrel twist rate of 1:7 or 1:8 both should adequately stabilize the projectile. This process should be done with any new projectile you use to prevent damage.
