Thread adapter for GSG-15, M15, and MK22

This is an adapter to thread a regular 1/2"-28 muzzle device onto your GSG-15, Mauser M15, or ISSC MK22! This adapter converts the female flash hider thread on the barrel sleeve to a 1/2"-28 male thread on the barrel.

Because the barrel isn’t centered in the sleeve the adapter needs to be manually centered using set screws, so I only recommend using this adapter with devices that have ample clearance (such as flash hiders, fake cans, or muzzle brakes meant for larger calibers). Please use caution when tightening the set screws to ensure that the adapter is properly centered before installing a muzzle device.

The cost for this part is $35 + $20 shipping within Canada; shipping can be combined with other items so check out my other ads for more parts and accessories. Also note that all of my products are made-to-order so please allow a few days for production before it ships.

CANADA POST UPDATE: To avoid delays, we will be shipping via courier during the CP strike. We will keep our flat rate of $20 shipping and cover the additional shipping cost for most locations for the time being (not including $5 letter mail items, those will need to be shipped in a box). Please note that couriers may have trouble delivering to PO boxes or rural addresses. If there is an issue with shipping we will contact you ASAP, and will make every effort to get you your package in a timely manner.

Please note this ad is for the adapter and thread protector only and that the muzzle device shown is not included!
