Firstly, see below. This mod is largely obsolete and is not being maintained due to the development of Magwell classes.
Secondly, I'm assuming you mean the Accuracy International AXMC series? If so, there's no effect on those weapons when running this addon as no RHS weapon has the same mag well pattern as the accuracy international weapons.

will this work for the sniper rifle mod pack?

Yeah I figured out the compat patch but am noticing those exact issues.

This mod is largely obsolete due to CBA magazine wells.
So it is possible to make a small compatibility mod that adds the RHS M249 belts to the LAMG. However, be aware that the re-load animation is associated with the magazine not the weapon so you will get the M249 re-load animations (which is much longer and not synced with the other animations.)

I can't remember if the M240 uses magazine proxies but the LW-AMG does not. So you will get no visual difference adding M240 magazines to the LW-AMG mag well class

if not, could you direct me to what I'd need to write a compat file to make that happen?

Any chance this will get updated so the LAMG/AMG can use RHS 240/249 belts like it can IRL?

Fantastic news, thanks much, looking forward to it. Thanks for all your work so far; was very pleasantly surprised to see the Knights LAMG included recently, overall, outstanding.

I plan to update this once RHS 0.4.9 releases. I think with the event of magwells, magazine proxies etc. I might be able to simplify this very significantly.
I strongly suspect I will be able to remove ACE dependencies at that point.

@Steve: Possibility of having this implemented for the Vanilla version, or am I behind the times and that is already done? I appreciate the otherwise thorough support you've maintained for the non-ACE userbase.
