Description
These 62 grain green tips are similar to what the US Military uses in their M16/M4 carbine platforms. The heavier bullet does great stabilizing in the 1:7 through 1:9 twist rate barrels, but likes the 1:7 and 1:8 most.
The green tip on the M855 is a steel tip that is designed for greater penetration into hard surfaces, but is not necessarily an armor piercing round.
This will do well in most AR-15 rifles chambered in 5.56 NATO, but not necessarily those chambered in .223 Remington.
