Custom Crosman 2250b

   Just got back the parts form the guy down the road who was lathing up some parts for this build. 
Here is what it is up to. Modified a CR600w suppressor to fit the barrel what a difference it make to the sound! Steel breech kit, dovetail to Picatinny scope mount, high 30mm scope rings for the Centrepoint side focus scope (not sure if this scope is an overkill yet) but I have another one on my CR600w and I absolutely love them. Next the bulk fill tank that turns this into an AR-15 looking rifle (connection from tank to rifle not complete as I need a custom high pressure hose so that will be next weeks job) 

Also need some pistol grips but may down the track do a carbon fiber grip when I have time.

	I haven't ruled out machining the steel breech to fit a CR600w magazine yet either. I wish I had my Solidworks cad license still to draw one up and get it machined from scratch.

	Thats looking cool! They are a great gun to modify. If you do carbon fibre greip, see if you can get some carbon fibre look vinyl and wrap the co2 bottle to match

	Good stuff. Will the bottle connect through the back, or will you use a hose to the front?

	You all know I love my carbon haha, wondering about either wraping the bottle or doing a carbon sleeve with butstock ... Options are endless just need time. Bottle will connect with hose up the LHS to a bulk fill adapter.

	I wonder if you could make the whole hammer system hollow, like Air Arms and put a pipe straight through into the valve and seal off the front?? Would be a great project.

	Yes I have wondered that. Also wandered how the air force texam etc do it too. Or they might have a reversed valve and hammer system

	Well had the day off and ended up fitting the bulk fill system on my 2250 braided hose and fittings look a bit too big so its now got a steampunk look with brass fittings. will paint them matt black in due course. Pressure gauge working firing well, now off pest controlling. Drilling this hole may or may not have voided the warranty LOL Proudly beside my bulk filled and modified cr600w

	Looking good! Just needs a butt stock that fits on the bottle

	Sweet. Youll be stoked to have it running on bulk. Steam punk is in. Throw some for no reason at all cogs on it and paint it copper and brass 😁😊 Im assuming you get no barrel lift on cr600. Whats it like for front end weight. Nice work. Edited by kruzaroad - 05 Oct 2022 at 4:31pm

	Installed a new scope today. Discovery VT-R 3-9X40AC Very clear glass edge to edge with no distortion. I love the pellet storage on left of elevation turret, saves fumbling around between shots (only holds .22 size pellets) The scope is sitting too low to get a clear sight through so will change them to high mounts asap.

	I'll have a look later today, I think I've got a taller set of scope mounts in car. what size tube on your scope. Interesting cap on scope, it come with scope? I'm looking for a faster way to hold a follow up pellet than taking tin out of pocket. Don't want loose in pouch and looking at pellet pen. is it side ao or is that just for pellets.

	That looks great. Did you tap into the side of a canister, or make an adapter? To hold pellets close to the breech, I have cut a strip of dense foam, like jandal material, with undersized holes and pellets pushed in. Fairly basic, but it works.

	Cheers Pauly got a piece of yoga mat I could use. ( using old camping sleeping mat in tins, found soldering iron makes perfect holes) Found scope mounts billbob dimension below.
