Combo 3-LUG & 1/2 x 28  Threaded Adapter with Thread Protector - Installed on your supplied barrel

Price: $209.00 

Price includes the following:  

• Thread your supplied barrel for adapter installation.  

​

• Press and pin barrel in your supplied receiver.

​

• Permanently attach Combo adapter (adapter and thread protector possesses Nitride finish).  

NOTE:  

Pressing barrel in and out will result in minor scuff marks on barrel.  For those wanting the upper refinished, we can refinish the entire upper in Cerakote black, Czech grey or Czech blue for $148.00.  The COMBO 3-LUG adapter retains the Nitride finish and the 1/2x28 adapter will match the receiver color as demonstrated in the photos and video.  If you want the refinish job for $148.00, please state this in the comments section on your Service Request Form. 

​

IMPORTANT NOTE:  If your barrel has been Nitrided, the 3 LUG Combo adapter CANNOT be installed.  Reason: the Nitride finish must be removed before threading and this reduced Outside Diameter (O.D.) is too small for threading.  

All Nitride barrels CAN have the 1/2x28 thread adapter installed as the thread pitch uses the necessary smaller O.D. 

* To confirm, Czech Small Arms and original surplus barrels are NOT Nitrided.
