OPTION E
This thread adapter is 1/2″ x 28 TPI to 5/8″ x 24, to allow the use of .300 cal silencers etc on many .223/5.56mm barrel threads.

For fitting alternative silencers / moderators / muzzle brakes.
The flat edges allow for fitting with a 3/4″ wrench.
The majority of UK airguns, rimfire rifles and some smaller calibre centerfire rifles (.17, .17HMR, .22WMR, .22LR, .222Rem, .243Win) are usually 1/2 UNF (1/2x20 TPI), if threaded at all, and of course if not re-threaded.
The majority of larger calibers (.30>) are usually 1/2x28 UNEF or 5/8x24 as the next most common.
1/2-20 TPI = UNF ~ Unified National Fine thread.
1/2-28 TPI = UNEF ~ Unified National Extra Fine thread.
5/8-18 TPI = UNF ~ 18 threads per inch.
5/8-24 TPI = UNEF ~ 24 threads per inch.
5/8-24 TPI = many barrel cleaning solvent traps.
3/4-16 TPI = many metal oil filters (Chrysler, Ford, Jeep, etc).
13/16-16 TPI = other metal oil filters (AMC, GM, WIX etc).
Please always verify the adapter and muzzle device you have and intend to use is suitable for the calibre and always insure perfect alignment before use.
