DonnyFL AirForce Texan Adapter




This adapter is for the full length Texan rifle! Not for use with the Carbine, SS, or LSS models.


  • Made of steel
  • M18x1 threads compatible with .357 Ronin or Emperor with M18x1 endcap
  • Comes with black anodized Aluminum thread protector
  • Adapters are tight fit and have two set screws (M4) to help secure to the barrel
  • Very tight fit, may require some 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 slide on the adapter. Let it set overnight.

The following are the inner diameter for my adapters:

.308/357 = 16mm or .625 inches “A34”

.308/.357 = 17mm or .67inches “A95”

.457 = .707 to .71 inches

Two sizes for .50 (please use a caliper and measure your barrel’s outer diameter)

.50 =  18.83 mm

.50 = 19.1 mm

Additional information


.308, .357, .457, .50 (18.83mm), .50 (19.1mm)
