Contour/Thread For Allen Engineering Collar


SKU: N/A Categories/Brands: ,


We will adapt your stripped barrel to accept our custom made collar for any of the Allen Engineering or OPS INC Suppressors. Price includes required contouring, 1 custom collar and threading.  This is a service we only offer together and will not perform on a barrel we did not thread.  Don’t send us your collar, we won’t use it. This is not a customizable service.
***We cannot do all pencil contour barrels. The contoured barrel area must be a larger OD than the threads enough that it can be reduced to contour a shoulder.

The lengths and dimensions are based on the math needed to mount the suppressor properly based on the length of the barrel. If you are sending a barrel you want cut down, be sure to note length in comment section at checkout. i.e. 20″ barrel cut to 16″.

OPS 12th = AEM5/AE30

This is for a barrel only. Do not send a barrel attached to a receiver.

Turn around is 10-15 business days for this service.

This service for SCAR barrels sent with the gas block attached is $280.00.
