Rifle Ammunition


Accurate, powerful and reliable, Extreme Shock has a rifle round for all
situations where accuracy and stopping power is crucial, yet excessive
penetration is of the utmost concern.  Tactical urban operations and hunting
environments would be ideal situations for these quality rounds.  All Extreme
Shock rifle rounds contain the same NyTrilium core as their legendary pistol
rounds, and are guaranteed to provide maximum stopping power.  At the
same time, the chance of creating an exit wound is greatly reduced, as the
NyTrilium bullet fragments into hundreds of wound channels upon impact.  
 
 
 Extreme Shock .223 (5.56mm NATO) Advanced, Subsonic Round, 127 grain, Hollow point, frangible ammunition. 975 fps, Box of 20  

Designed for use with M-4 and M-16 style weapons, this round is tailored for use in close-quarters-combat scenarios. Velocity of 975 fps provides controlled penetration in urban areas and other sensitive environments. The round will fully cycle the slide in both semi-automatic and fully automatic firing modes. When combined with an ASP suppressor (or other model), the round enables super-quiet operation for both military and law enforcement. Will deliver 1 MOA accuracy at 100 yards.
