The rest of the aluminum parts are black except for the tubes which can be clear or black. We can also make red/blue/clear in both US FT & Hunter. Wave the flag! Made in USA.

Left Handed US FT or Hunters are no extra Charge. There is a one hour labor charge to convert a Right handed US FT to Left Handed Configuration. The latest refinement is a port restrictor in the Transfer Port. The barrel Mount is slit to allow for easy Indexing, Barrel/Caliber Swap plus a more serviceable Barrel fixing arrangement. The two right action fasteners can be loosened to allow the barrel to be turned in the barrel mount or swapped out in a few minutes. Transfer Ports are all fitted with an o-ring now so barrels do not need o-ring grooves and it is easy to test raw 16MM barrel blanks that only have the leade work and crown down. Caliber changes are no nonsense. Hammers now have threaded holes so weights can be added to make more duration and power. With the port restrictor, hammer weight and hammer spring adjust it is pretty easy to get these things adjusted for different power levels with just wrenches.

Under the cheek piece, adjusted by the same wrench size that fits the cheek piece bolt you can adjust the Striker Spring to allow you to fine tune the striker force. I like to run that about 4 turns in from the back of the block and then I go to my Port restrictor to dial out the wasted air. Run that in or back it out till you get the speed you want.
