how can you mount weaver type scope rings on this rifle?
Not without adapters. You would want 11mm dovetail mounts
What is the weight of trigger pull and is it adjustable?
The only adj screw is to set the partition between stage one and two. To adj the pull wt you need to remove the trigger blade and swap out the little coil spring inside. I did and went from ~5lbs to <1.5. Misc spring I found at Home Depot and bent it until I was happy. The oem spring is .252" OD of .035" wire and ~.530" long. Pretty strong little guy. My new one is .026 wire and no doubt a weaker metal too. After you remove the stock I believe it's just one E-clip to get the trigger out. The sear will rotate down and spring should fall out. From there you'll see how it goes back in.
The CBT trigger is adjustable but usually comes out of the box in the 4-5 lbs range
what is the cocking load for this rifle?
About 35 lbs
I like this gun because it has open sights. Does it have any baffles, or will it be louder then the scoped versions of the nitro 2, with the thicker barrel/shroud?
Never tried the NP2 w/o the suppressor but the older Trail and XL it makes a big difference. The shooter mostly hears the guns mechanical noise, but the target hears mostly muzzle blast on a gun w/o a suppressor. If I had this gun I'd buy the suppressor and make it fit, or simply buy the suppressed version of the gun. Plus the shroud makes for a much nicer and easier cocking lever than a small dia barrel with a spike on the end.
It does not have any baffles. It may be slightly louder, but the majority of the noise from a gas piston/spring gun, comes from the action itself, so the noise increase shouldn't be extreme
Does this airgun have a "CREEP STOP HOLE" drilled in the receiver top?
I can't imagine it would not... In the pix it appears there's a hole or something there. Either way I'd get one of these two mounts; Leapers Accushot 1" Rings, Medium,... or Leapers Accushot 1-Pc Mount w/1"..., which are very strong, look sweet and very cheap. Plus either are capable of holding w/o the hole b/c they have exceptionally strong clamping. I prefer the looks of the one-piece, but for appearance and extra clamping I add two extra screws. I use them on guns that don't have a hole, or the hole is not in the right spot, or the gun is too nice and I don't want a pin marring the metal.
Yes it does have a scope stop hole.
Would like to know if the muzzle break is removable\threaded and can be replaced with an aftermarket suppressor\silencer, will appreciate any feedback :)
If it is 1/2-20 as Steve says then I'd imagine it's simply the normal NP2 barrel? If so then you can buy the oem baffle, shroud and taper from Crosman which is ~$9.50 + $4 ship and it'll go right on. Parts list for the #'s: https://tinyurl.com/NP2Wparts and while ordering I'd get a new main seal; CRS5177-012 which for some reason they don't show a part # for. If you do this let us know. I doubt any aftermarket suppressor would work as well, and they'd certainly be many times the $ and possibly risky to possess.
Yes it can be removed . Unknown thread size ?
