Rat works makes an adapter that takes it to 1/2x28

An E4 should be 1/2"-28 but the other barrels are M13x1LH.

My E4 is 1/2x28.

Make sure to double check. The earlier msar ran M18 metric left hand. I'm guessing they didn't change it.

Just to clarify, not all E4's are 1/2x28. They have been coming from the factory with "surplus" STG barrels.

Definitely double check. My month old E4 came with 13-1LH AUG threads.

If it has a silver lock ring on the flash hider then it has the 13-1lh threads.
