AR-15 Magazine Clearance?

[STI_1911_Guy]

I was wondering how much room there should be between the tip of the bullet and the front of the magazine when loaded into the magazine. Is it good as long as it functions or is there a "set amount" of room that is recommended? I tried finding info on this subject but if you know of a post i missed i apologize.

Measure, make up some dummy rounds and try their function for yourself..
I recently tried some at 2.285" base to tip, there appeared to be at nice bit of clearance, but they still hung up, so I quit fooling around and stayed at 2.260" book length.

If it functions, your good to go!

It just has to have enough extra space to function and not hang up in the mags you are using.

I believe the PMags let you go a bit longer with the rounds than USGI aluminum mags will.

you want a decent amount of clearance if you want to insure function , i noticed hollow point rounds tend to hang up more then soft point or fmj

If you need to load long rounds in to the mags get HK HRM mags. The real ones and not the South Korean copies.
