What is the difference between the FN M249s para Gen 1 and Gen 2. If you look at the pictures, you can see a difference between the stocks and handguards. Does anyone know if there is any differences than basically cosmetic?
There might be something going on with the Gen 2 gas system. The piston block under the barrel looks different.
