The Stoner LMG, is IMO, the finest beltfed S.A.W. I've ever had the chance to experience. Hands down.
I've got a 240B and 249Para at my disposal, Really wish I had a LMG.
That said, I've been involved in converting a Robinson M96 into a beltfed using some heavily modified LMG parts.
That was pretty cool too. Robinson didn't want to sell the M96 they discontinued and we didn't want to sell
plans for the beltfed conversion. It was and still is a standoff. They couldn't ever get a conversion to run.
I think they're mad 'bout that.
