Benjamin fortitude question

Hey guys I just wanted to ask if any of you have done a tear down of the frontier and if so could you post pictures of what the regulator set up looks like and also I am curious if the reciever would bolt on to a crosman 2240 or a 1377. Any pics or advice would be appreciated. I am hoping to jury rig a cheaper than b&m solution for the 2240 multishot problem. While your at it any advice on installing the air tube and regulator from the frontier on to the 2240 would be cool to. Again I dont know if any of this is possible but I would like to find out preferably before I buy a ton of airguns ty
 
Are you looking to turn the Fortitude into a CO2 cartridge gun? The Fortitude receiver is mounted with 4 hex cap screws two forward of the mag well and two in the rear and the are on the right left sides of the scope rail. You could put a 22xxx/13xxx PRod pistol grip trigger group and use either a 1399 stock and I am pretty sure the AR stock adapter will fit the Fortitude. The pcp reservoirs to receivers are a 4 bolt mating vs 2 of the CO 2 reservoir
 
Naw I am building a 2240 pcp airgun just for fun and was wondering if the fortitude action would just bolt on yo the 2240. B&m makes one but its super expensive. Like as expensive as a fortitude! So i figure buy a fortitude and switch out the multishot with a single shot maximus action and put the multi shot on my pistol. Now i have 2 guns for the same price as b&M.
