I bought one of their repeater breeches for the 2240 pic and some info below. It is extremely well made with very tight tolerances but smooth lever operation. Had a long in depth breech comparison review here on the forum but it went away after some months for some unknown reason. Part of it still exists on the Crosman forum though.

One will need to chop off the T-port on a stock Crosman barrel and turn down the first 2.5 inches or so.005in to make it fit in the Custom Air breech. I just used an FX barrel liner and made a brass adapter.

ive got a chopped down tube and shroud of theirs. The one they sell is longer

In 22 cal with a 7.6" barrel, gun was shooting over 27fpe 😬
 
That's actually a gravity fed magazine off to the side, but I do have a few dirrerent sights I'll use

It has a lothar walther barrel that was cut to 7.6" and recrowned, re-choked by WHITEFANG. GMAC left hand breech (fitment is top notch on these). I had to chop and hand fit it for this parts combo, however.

Marauder pistol drop sear trigger group. And custom hammer with adjustable striker. I can fine tune where the hammer hits, and how far the valve is opened. 

Also installed a huma regulator. Gun is currently tuned to shoot 600fps with 18.13gr jsb. Over 100 shot count, 300 bar fill, I only fill to 250, however

That setup is looking clean! The performance is even more impressive, 100 shots on that little gun is phenomenal! Are you running any other mods in it? How many cc’s is the cylinder?

Wow - very cool, unique, and outstanding performance specs - and a nice Tom West stock to pull it all together - WELL DONE SIR - SALUTE!!

Thanks 🙂 there was lots of work and hand fitting involved. It took about 7 months to really pull together, and I am still tweaking it. I measured roughly 160ccs in the 220mm air tube without the regulator. The 290mm air tube I have is about 210cc I want to say. I'm tempted to build another with a long barrel. And the longer 290mm air tube.
