Izzy SRTA...needs M2 training bolt to function your M4 correctly. Remember, this is still a lethal round at short range.

Yep - I bought a bunch of it from KYImports back around '05 or '06.
"Cartridge, 5.56-mm Short-Range Training Ammunition (SRTA), M862. (Used in
all rifles.) The M862 SRTA is designed exclusively for training. It can be used in lieu of service ammunition on indoor ranges and by units that have a limited
range fan that does not allow the firing of service ammunition. SRTA ammunition must be used with the M2 training bolt.
Although SRTA closely replicates the trajectory and characteristics of service ammunition out to 25 meters, it should not be used to set battle sight zero of weapons to fire service ammunition. The settings that are placed on the sights for SRTA could be different for service ammunition.
If adequate range facilities are not available for sustainment training, SRTA can be used for any firing exercise of 25 meters or less. This includes the 25-meter scaled silhouette,
25-meter alternate qualification course, and quick-fire training. SRTA can also be used for Urban Operations training."
