Easiest-Most Difficult PCP's to Work On?

Easiest to work on so far has been my Cricket. 

Anyone here ever work on the old Crosman 670’s(May be wrong on the last two numbers of the model number type), but it is the 22 caliber CO2 with forearm pump like a shotgun? That was my first to work on, and very tricky at that time. It’s like I needed a second set of hands.

Easiest: 2240

Hardest: Shinsung Fire 9mm. Need spanner wrenches, EXTRA long flat head or long file, and all the usual equipment. After doing it one time it’s not as daunting

When I eventually have to open my huben and sk19 they will probably be the hardest

Easiest - Edguns.

Hardest - FX Impact. It is simply a sick vision of some Swede who hates simplicity.

Easiest and hardest all in one for me have been crosman. That is until you de burr everything. Many an oring have been sliced by the rough edges on the crosman tubes.

I have to second RJ specifically on the Umarex Gauntlet. They make no effort at all to deburr or chamfer the INSIDE of any hole they drill on the G. That means that when you take it apart your are going to scalp at least 2, 3 or 4 orings so you better have a lot of orings on hand before you start and also you better have a decent deburr/chamfer tool before you start or you are going to scalp more orings when you try to put it back together without first deburring every hole on the thing.

Not really gun specific, but the "most difficult" thing that I have run into, on a pcp, was removing Ninja Regulators from their bottles. PCP airguns, once gased-down, can be complex and tedious, and that goes away with knowledge and repetition, but dealing with a long compressed spring of an FWB124 is always there. PCP are easy to work on comparatively, and require less space to do so. If you have space and a workshop, the problems become far less.

easiest - Marauder. Few parts, easy assembly

Hardest - Impact. Just so blasted complex once you get into the gun. Adjustments are easy once you get it back together, but getting it back together takes patience!

I havent built/worked on many but brococks are pretty simple. Not many parts. Dont need any special tools either.
