My latest 2240 build. I'm in love with this one.

I just finished up my latest carbine build to where I could shoot it.  Here's the list of mods. 

-BNM weaver repeater breach
-BNM shroud
-BNM retainer
-2260 lower tube
-BOSS Maxflow valve
-Crosman 12" .22 barrel
-Bluefork Designs trigger frame
-MFT grip
-UTG Bugbuster 3-9
-Magpul fore grip rail kit
-Collapsable stock built from 3/4" steel tube, 7/16" shaft collars, stock 2240 barrel
-Wood done by me.  The fore grip is going to be redone.  I hacked one out real quick so I could get it mounted up to shoot.

The target picture was 4x 3 shot groups @ 10 yards offhand.  I haven't shot anything through a 12" barrel yet but I'm pretty sure it should group well at 20 yards like my 18" and 24" 2240's.  Also, here's my son's new 18"er.  I put it together and cut the stock down for his short pull length.  I got some of that Black/Cinimmon laminate left so I'll do something with the fore grip later.

Sharp looking shooter. What kind of pellet speed are you getting? I assume you are running it off cartridges.

I haven't chrono'ed it yet with the 12"er but I'm guessing it will be in the upper 600's.  This same setup with an 18" barrel was shooting 700's in 100 degree heat so upper 600's should be about right.  Also it's a bulk fill with that long 2260 lower tube.  I get about 35 good shots off of it with the BOSS valve w/ economy bulk adapter and about 30ish with the max flow bulk adapter.  I used to run this setup on 25g cartridges but the BOSS valve knocks the shot count down to 15.

The second rifle runs off of 25 gram cartridges.  I'm about to convert it to a 95 gram and 9oz tank capable gun tonight or tomorrow.
