View Full Version : Metric / Inch Gasplug Interchangeability?

I hope I spelled Interchangeability right!

Just wondering if an Inch (L1A1) Gas Plug would work in a Metric gas Block.

I believe they will work "properly" in some of the early short gas-plug style of FN pattern gas blocks.

The wide and narrow lugs are reversed on an inch gas plug, so if you are turning the plug to fire a gernade the inch will pop out half way through the rotation.
And the inch is slightly shorter.

Inch and metric gas plugs are not interchangeable. However, you can use an inch gas plug on a Israeli gas block, but not the other way around.
