I'm trying to tinker on a metric FN FAL and metric gas plugs are currently unobtanium in my price range. Got to thinking about the development history and realized Numrich has a pile of partially finished FN-49 gas plugs at a very attractive price. However, I don't know how close the two parts are dimensionally.
Does anyone have the ability to check whether an FN-49 gas plug will fit the FAL gas block?
Alternatively, can someone with an FN-49 measure their gas plug (specifically, the diameter and OAL from the lugs to the gas piston side, and the lug dimensions)? I have the ability to adapt these if necessary but want to make sure there is enough material to start with.
Thanks in advance for your help!
