Thank for your advices guys, so we know that m240 have a heat shield, check, but how would you tell apart L7 from original FN MAG?
The only real visual differences between the FN MAG and L7A2 are carrying handle (It's conical and ribbed on the L7A2) and the dovetail bracket on the side of the receiver on the L7A2. Oh, and the buttstock.
The differences between the FN MAG/L7A2 and M240 are more numerous but include:
Flash eliminator.
Carrying handle (Between L7 and M240. The FN MAG and M240 use the same one.)
The buttstock.
Rail on the top cover.
Gas regulator.
Heat shield over the barrel on the M240 (although not every M240 has one.)
Retaining pin on the pistol grip.
Above mentioned sight bracket on the L7A2.
There are others, those were just off the top of my head.
