Might need to rethink your grip
When it comes time to mounting a flashlight on your M4 Carbine you might have to rethink the placement of your grips. If you have a tradition A2 it might not be so bad, I have for several years not used pressure switches on my M4 Carbines because I’ve seen them snag or fail so many times. Putting one more switch or screwed on attachment on my carbine means one more thing that can fail on me. Considering the number of failures I’ve witnessed with guns, I don’t want to have to worry about getting a light on at a crucial moment.
Depending on your level of vigilance, you may be in the same camp as I am, but really want to add on those lights and switches. Always knowing how to deal with a failure is important and many have changed their magpul accessories out on firearms only to realize they can’t move the same way. There are some very nice light mounts being made that actually sit very far forward and close to the barrel of the firearm which in all reality, is the best place for a laser or a white light. The magpul angled foregrips are something that I really feel comfortable using, but it’s hard to turn a light switch on and off without a pressure switch in this position.
