So for about the last 24 months, I've had her on a serious diet. Now I am happy to
report that she lost nearly 13 ounces and is feeling so much better. And let me
say one thing, when I pick her up with one hand now she is light as a feather.
Well, almost a feather.
Things I have done so far:
OEM main tube was lightened by me.
Barrel is OEM and trimmed down by me.
Main tube plug is made of Delrin by me.
Gas cap is aluminum, comes from HPA and bored out by me.
Hammer is made from Delrin by me with a modified 1701P striker.
Valve is an aluminum Disco rear end with a brass Pro-Top by Anthony.
Trigger grip frame is aluminum by Bluefork Design and then hogged out by Gregg.
Front barrel band is aluminum, made by Anthony, drilled by Rich and milled by me.
do not be afraid to tear down the 22xx. comparing it to the 2200 is like rebuilding a single cylinder 2 stroke dirtbike engine vs. rebuilding a northstar v8 cadillac engine... to change the spring you only need to remove the top rear screw and the rear pistol grip assembly screw. the rear cap will pop out under the tension of the hammer spring. replace, recap, re screw. done. the only tough part is the little allen screw inside the breach... if you are not careful they strip very easily... I actually take them out and cut a slot in the middle of the head to use a flat head screwdriver instead...
By the way... 600 fps is plenty for such small carbine/pistol. it is about 12 fpe, and about as hard as a P rod from the factory... my hunting number is even lower than that... 500 fps with 14.3 gr is a lot of whomp. And 550 fps with the 10.5 gr .177 is plenty for good 60 yards shots...
