Larry sure is a craftsman, look at those grips

Just about got this finished (for now...LOL) Added a stippled walnut matching forearm to go with the 10m grips. 
Also added a Williams notch sight. The valve is stock. For the distance I shoot this pistol, it made no sense to me to mod the valve. 

I was after shot consistency, accuracy and could not get it. It is 7.5" 22 cal. barrel and about 20 shots around 458 fps and dropping off to 415 around the 25th shot.

Reworked the trigger to 1.25 lbs. Works smooth, but not a great trigger :>). Under 1 lb and it fired without touching the trigger when bumped.

Later I changed out to a 10.5", .177 barrel with a Steve's HDD. Now getting around 55 good shots with a top range of 575 fps to 408 fps by shot 55.

Two things I really like about the HDD, the gun shoots quieter and the number of shots i'm now getting. IMO, the HDD is a device really worth the money!

Anyway, here are a few photos of the project (may end up modding the valve also...hehehe)

Check out the vent rib that Larry made for his 2240

This is a wild looking design

HI guys here are some pics to post with new RJ long breech- with extended probe and handle by Roy -breech riser is made of black delrin and shoulder stock is carbon fiber and forearm stock is made of black delrin all made by LarryR-Muzzle brake by Gil-Leapers Bug Buster II 6x32 scope with BSA laser and light-ported valve and ported barrel-dead accurate up to 30 yrds if i do my part!---Rich

Love the grips and brass on this one.

Just finished this one. After haveing a Custom 2240 done by Roy I had to do one myself just to say I did it. here is the end result. I must say it was very fun to build & very easy to boot.. If anyone out there doesn`t think they should or can, You have to try it!! Outside Parts on this gun consists of Brass end caps & Fiber Optic front sight from Roy, RJ Machine regular Right with cutout Breech, RB Gold Miner Grips which I got lucky & got 2 sets of the Target variants. anyone interested he did say he had a few Sportsman sets left only 25 sets of each were done. A set of Kwik-Site mounts & a Tasco Pro-Point makes for one AWESOME tack driver.

Roy built this one for Brent.  Brent liked it so much that he built the "Proto-Sniper" above

Recieved this Saturday afternoon around 4:30pm.  I scoped it & placed it`s new skins on it & by 5:00pm I was putting .22`s in a penny sized circle at 30 yards a HUGE THANKS goes out the Roy Weid for building such a AWESOME piece of art, Ralph @ RB Grips for his beautiful Gold Miner Grips, & Robert @ RJ Machine for his wondeful High Rise Breech...Im seriously HOOKED & Im already starting on one myself as parts come in I`ll be doing the work in my spare time Im shooting for open sights on this one I think who knows ??...I still have a Brass Co2 end cap for this one in route which will only make it look MO-BETTER.

Rob in NC's 2240 PCP

Shiny! Nice Lam's too

Next up…. And my BABY… is a 2240 PCP by Joe. This gun started out as an AWESOME 2240 built by Art Braden. The gun was perfect, but I am not much of a CO2 guy. Joe made a custom PCP tube, valve, and hammer for it. Bottom line is 20 shots at around 16-18fpe. More if I accept a wider velocity spread. Only thing missing now is a silver trigger shoe from Gil and the package will be PERFECT.

This one is getting around 30 shots at 22fpe. VERY consistent and very accurate.  the gun was made
by Joe Bontrager. The stock is a Richards Micro Fit stock that Rob
finished....

Look at the details that Buck put in to his 2540

Polished Early model CB right hand only Ultimate breech and Bolt -the polishing is a five step process-labor intensive-Crosman 3-9X40 scope-Accushot med rings-Custom shroud 1.25" X 9"long made out of a old Maglite flashlight and can be baffled if chosen all internals are stock shoots good in the backyard.. I really like to modify crosmans but like so many others that I have done this to will go up for sale soon so I can start on another in fact Ive got 2 more just waiting for me hehehehe.....

This is my modded 2240 that I have been slowly putting together. Most of the upgrades are from Grant Stace. From Grant, I have acquired the breech and barrel band setup and bolt assembly. Then came the Stace trigger (this makes the 2240 feel like my Browning Buckmark) plus the tri winged gas cap, and finally the brass sight which puts a nice finishing touch to the 2240. I think the next thing for me to do to this project is to remove the "This is a toy" writing on the side. That will have to be a Spring project. I did this to my other 2240, but the writing wasn't as deeply engraved on the tube. I may try to pick up another tube somewhere and then work it over little by little, and then change it out, so I don't have pieces to try to keep track of during the project.
I really like the heft that the quality metal parts give to this pistol.

Many thanks to Grant Stace, who make these beautiful upgrades available.

This is the pistol I have been waiting to build for a long time now. Last week the final parts I needed to complete the project arrived and I was on my way. Here is what I can tell you so far.

My initial impressions of the gun were that it was very well balanced for a pistol of its size. I was afraid it would be a bit too heavy with the long steel breech and 10" barrel, but I was pleasantly surprised to find that it felt quite nice in my hand. Not too heavy or off balanced towards the front or rear at all. It actually balances quite well considering. Keep in mind that the shroud is just aluminum tube that is basically empty for the last 5" so it doesn't weigh very much on the front end. I loaded up a CO2 powerlet, fired a piercing shot and then loaded a .177cal RWS Basic wadcutter pellet into the chamber. This breech, bolt and barrel combo feeds pellets better than any gun I own. It is super smooth with no pellet hang up, which the Crosman 22XX and 13XX are notorious for. I took aim at my target and pulled the trigger slowly but deliberately and all I heard was the hammer hitting the valve stem, then the pellet hitting the target. Man, this thing is quiet! It’s perfect for my backyard shooting needs. I could shoot this thing in my bedroom and no one else in the house would hear it, it's that quiet. The trigger pull was very smooth with a crisp release at ~2lbs. I took a couple more shots at the target to get the red dot sighted in and then I shot a couple of groups. One was a 10 shot off hand group at 12 meters that I could cover with a dime. The other was a 5 shot group at 12 meters, with the gun loosely rested on a soft and somewhat shaky rest and it was no more than 1/4" ctc. There are 2 photos of the groups I shot at the end of this post. Needless to say, I was very content with the accuracy of this pistol, especially considering I was shooting my favorite cheapo wadcutter pellet. I have literally thousands of those RWS Basics on hand and all of my .177cal guns love them. They work perfect for punching paper, plinking at cans and whacking the occasional small pest if needed. I consider myself very lucky to own yet another .177cal that shoots cheap pellets, accurately.

I don't have any chrony numbers yet, but I will get around to testing all that out later. My best guess is, on low power with the hdd, I am pushing those 7.0gr pellets in the mid 500-600fps range. That is more than enough power to punch through paper and plink all day long at my 15 meter max distance backyard range. I can increase the preload on the hammer spring with the power adjuster and get more power, but at the cost of fewer shots per CO2 powerlet. I don't have a shot count per cartridge yet either, as I am still on the first one after 40+ shots. It looks like I will be getting quite a few shots per powerlet with this setup, which is what I was aiming for with the hdd, stock valve and power adjuster set on low.

I will get you guys some numbers on the fps and shot count here shortly to confirm what this setup is putting out. I can tell you that I am very happy with the results though. What matters most to me, is that it puts the pellets where I aim at the distance I shoot at. Everything else is gravy.

I have many people to thank for helping me with this project. I couldn't have done it without you guys! I would like to thank Grant Stace the Kiwi for his incredible breech (good ol' #59) and integrated barrel band with polished stainless steel extended bolt and handle, blued steel power adjuster with his aftermarket hammer spring and delrin guide and last but not least a winged CO2 cap from him as well. All top shelf parts in form, looks and function. Grant’s parts make any gun better and that’s a fact. I would also like to thank Mike Tiehen at TKO Airguns for his 9" Stage V barrel shroud, black anodized target trigger, complete trigger kit with hardened sear and trigger pins, lightened trigger spring and delrin spring guide and the 10" .177cal Crosman barrel on which he custom crowned and polished the lead in for me. Your stuff is terrific Mike! I love the trigger and the trigger kit and it makes a huge difference in performance over the stock configuration. The shroud looks great and performs fantastic. Thanks for all the goodies that you sent me gratis! I owe you big time. I want to thank BigEd aka Ed Stack for making me a custom left handed RJ HDD for my build. He didn't have any of these made and went out of his way to custom machine me a left hander for an RJ breech. I needed the RJ breech type since Grant bores his bolt chamber to the same dimensions as the RJ Machine breeches. It works great Ed, fits like a glove. Thanks go out to Michael Chavka for the beautiful and highly functional black tactical target style grips that he custom made for me. They are coated with truck bed liner for that nice black look and superb durability that I wanted. They are extremely comfortable to shoot with and they look terrific. Lastly, I would like to thank my son Scott for buying me the Walther Top Point II 4 MOA red dot sight that is sitting on top of the gun. Great Father's day gift Scott, it works perfect.

Stephane's Custom Stace 2240

Al Stone's 2240

This is my first attempt to customize a 2240, I have done other guns in the past but never a Crosman, I live in the UK and Crosman is not the most popular airgun manufacturer but gaining ground with the Disco and Marauder, the problem is the price over here nearly twice what it is in the States.

I picked a 2240 for something to do this winter and as I post mostly on North American forums I figured out that I had better get familiar with Crosman products. I found the 2240 easy to work on and the basic gun well made, but spoiled by the use of plastic parts and not being available in .177 over the counter.

The criteria for the customization was that I should do away with the rifle type bolt, (I dislike rifle bolts on pistols) convert to .177 and design a easy to use power adjuster, also I wanted the mods to be in brass.

So to start with, I bought a new standard 2240 and a 10 ¼ .177 barrel and machined a breech to fit, the middle of the breech can be slid out and replaced with a .22 barrel and bolt assembly, the bolt itself is a straight pull to cock and when pushed forward it drops into a recess to lock it in place, it will also stay where you put it, no sliding forward when loading the pistol with it pointing down.

The rear of the breech is a five stage power adjuster, you just need to turn the adjuster ring through 90 deg to cover the full range, at the moment on the lowest setting it shoots around 530fps at 60*F with a very flat shot string, this can be turned up to around 575fps.

Also on the breech is a compact rear sight with adjustment for height and windage and the front sight is also adjustable and it sits on the end of the bit that keeps the noise level down, I have also fitted two barrel bands as I think it keeps the barrel more stable than the little screw under the breech to hold it down.

The trigger unit has had a complete rebuild with bushings for the trigger pivot and a wide shoe for comfort, also a trigger stop and lighter spring, and lastly a pair of carved grips slightly fatter than the originals.

All in all I am pleased with the results also it shoots well, using a bench rest it will shoot 16mm groups at 20m using iron sights, which is comparable to my Rohm target pistol, which makes me very happy with the result.
