Installing a Phrame? Allow us to machine your stock Phantom breech to fit. 
 
This service can only be done on CCI, EV, and ASP stock class breeches due to the fixture used. Ship us your breech (or drop-ship one directly from Extreme Velocity or Airsoldier Products), we will make the required cut, and ship it back to you. 
 
Please note - this is not a 7-day-a-week service. Turnaround times may be especially long during busy seasons or holidays. Send a message in advance if you require a quick turnaround time!
 
We also have published the specification if you prefer to use a local machinist, or are modifying a direct feed breech that won't fit in our fixture. 
 
And a recent update - by agreement with AirSoldier and following some testing, the famous ASP Detent Mod can now be added to this service. The breech will be machined for the two o-ring pockets after the Phrame mod is complete. As this is not "my" mod, though, I'm only offering it in conjunction with the Phrame mod.
