I thought I would go over what it took for me to get this baby where shes at
Starting at the front I added a TKO muzzel brake, recrowned 14.6" inch barrel, modded 1377 barrel support, discovery bolt and handle,
power adjuster is used to easily swap out hammer springs, Hi-Pac wrapped it and air tube in carbon fiber, lanyard for dust cap.
Made a frankenvalve.
Discovery back half co2 front. No other mods there. Next drop sear grip frame nirvanamod trigger. ground bump off bottom of grip frame
Added new hammer, cut to clear breech screw. upgraded hammer pin
The addition of the grip frame and hammer allow the use of a truly heavy hammer spring.From True Value( #44U it's 047 gauge wire. Cut down to about 1 and 7/8" long 5/16" dia. ) With a fill of a few hundred psi or so over "MSRP" (manufacturer's suggested rated pressure) 3200
14.3 CPHP +- 3 fps
To me this is now the perfect carbine. Thanks again Alex
And I've been wanting to thankyou for the Frankenvalve idea - I've since utilised this on two different HiPac setups, it works perfectly.
How hard was it to create the notch on the P-Rod hammer? Presently I'm using a notched 22XX hammer with the waist filled in w/JB Weld putty, and my #'s went south a little, as it now seems the hammer/striker might be too heavey?
Nice post & thanks for the info
