The ORIGINAL gathering place for a merry band of Three Percenters. (As denounced by Bill Clinton on CNN!)
M-4 is perfectly fine inside of 300M. Add 20" barrel for full-range and good performance with the most-standard 55 and 62 grain ammo. Does your squad include a DM with the rehabilitated M-14? Reach is good. pdxr13
Wondering how recruits are gonna do manual of arms with that extendable stock...comeandmakeit
The m4 isn't perfectly fine inside of 300m or anywhere else. Reason being is due the design, where the 20in barrel version has the gas port far enough away from the chamber for the pressure to have dropped and the case wall to have contracted as the round passed the gas port, not so with the m4. In the m4 or any short barrel non piston ar, the gas is still holding the fired case to the chamber walls upon extraction attempt, wich has resulted in pulled case heads, broken extraction parts, and broken bolts.Other than that I guess the corps is now a corps of carbinemen rather than riflemen.
