Which Rail to use

[exodus9824]

I need a commonly available rail for my project that can fit a logic umf and still allow for a fore grip. I was thinking about the am/mm rail but i dont know the length. and what about the mini-shadow rail from RPG?

The mini rails are am/mm length.

The mini rails are am/mm length.

Are the am/mm rails long enough? for a foregrip and logic umf?

I haven't dealt with the umf so I cannot answer that.

Per robnix it doesn't sound like it.

The UMF is to long for a classic rail and gets in the way of using a foregrip.

[MANN]

umf frames cannot use am/mm rails with foregrips.
