if you need a forward assist while at the range, something is terribly wrong. in combat I can see the need, but when you are shooting targets, you are going to live if you don't jam an out of spec round into the chamber to get it to fire.

you aren't in a life or death scenario. If you are planning on such a situation, make sure you shoot the gun beforehand and get it where you want it at.

other than that, there isn't a need unless you plan on shooting terrible ammo and not cleaning your gun for several thousand rounds.
