Note: Please measure the outer diameter of your barrel with a caliper before ordering and compare it with the size chart below. There may be slight barrel-to-barrel variations from the spec due to the thickness of the protective coating of your barrel. If your barrel is bigger than spec, contact us about a custom adapter.
Features:
- Made of steel
- M18x1 threads, compatible with big-bore Ronin, Emperor and Great Kami moderators with M18x1 endcaps
- Comes with a black anodized Aluminum thread protector
- Adapters are meant to be a tight fit and have two set screws (M4) to help secure to the barrel
- In some cases, proper installation may require sanding inside the adapter
- Uses 2mm hex keys for set screws
I would recommend putting a thin film of blue Loctite on the barrel, then sliding it into the adapter. Let the Loctite set overnight before shooting.
The following are the inner diameter for my adapters:
.257 = We do not currently have an adapter for this barrel. Check back soon.
There are two sizes for .308/357
.308/357 = 16mm or .625 inches "A34"
.308/.357 = 17mm or .67inches "A95"
.457 = .707 to .71 inches
There are two sizes for .50/.510
.50 = 18.83 mm (this is the older specification and is a custom order)
.50 = 19.1 mm
If you are setting up an AirForce Tex Rex we recommend either having a competent gunsmith thread your barrel with M18x1 threads or adding shallow dimples or divots under the set screws to enhance the hold of the caliber-specific adapter. Be sure to check the position of your adapter and make sure your moderator is fully threaded onto it to avoid failure.
