Title: Some 2240 mod questions - breech, barrel length, what scope/mount, etc.
Post by: matty on October 03, 2012, 06:14:33 PM
Hello!

I'm new here and bought a stock 2240 I want to mod and keep in pistol form.  In doing a ton of research, I found Mellon Air and it looks like I'll order most of the custom stuff through him.  A steel breech is on the way from Crosman.

At any rate, I have a few questions in relation to what I should order...

1. Scope - I'm looking at the Leapers Golden Image from Amazon (http://www.amazon.com/Leapers-Golden-Image-Integral-Weaver/dp/B001BQZSZ4).  It's my understanding I will need a 11mm to Weaver adapter for the breech - is this correct?  If so, I am looking at this one: 11mm to Weaver Mount (http://www.amazon.com/UTG-11mm-Weaver-Adapter-Adjustable/dp/B001CJ67E6/ref=pd_sim_sg_3).  Does this seem like a decent combination?  I don't want the sight to sit too high but it seems there aren't a lot of scopes that mount directly to the dovetail on the breech.  If there are, can you recommend some?  Also, does anybody have experience with the Leapers?  I'm also open to different suggestions.

2. Barrel - Thinking of 10" or 12" from Mr. Mellon but I don't want the gun to feel or look too front heavy.  Kind of leaning towards the 10" because I also plan on adding one of the nubbins at the end.  Does anybody have any experience with 10 vs 12 on the 2240?  I know it's vain but as I mentioned I want it to look balanced as well.

Sorry for the basic questions but I want to make sure I'm getting the right thing...I had ordered the Leapers earlier but cancelled because I didn't understand the need for the mounting bracket - I thought it just slid right on to the breech  :-[

Thanks!

A ten inch barrel is just fine for what your looking for, i think the red dot you want has the duel mount im not sure but i think you can flip the mount to fit crosman breech. If not the BSA will and save you some loot.I have two of the BSA red dots and really like them.

Thanks Crosshairs.  That BSA is something to consider.

+1 to the BSA RD sights, I have 2 of e'm, they are good for the price and the mount flips over for 3/8" or Weaver.

On scopes, you don't have to use the Weaver rings supplied, especially on co2 or pumper guns (no recoil). Just get a cheap set of 3/8" dovetail .22 rifle rings from any sporting goods and remount on scope  :-*

Matty,
I have one of those 11mm to Weaver adapters with a Leapers red dot sight and it works just fine for paper.  I had it mounted on a carbine and with the Crosman shoulder stock, I couldn't get a good cheek weld because the sight was too high.  Then I changed to a RAP4 (AR style) stock with a Mellon adapter and it was the perfect height.  As you are shooting it as a pistol instead of a carbine, it won't matter except that the sight will be a good ways from the barrel and that means that you have to judge your distances better if you are shooting it at different distances from where you sighted it in.  In other words, if you don't compensate for the different shooting distances, you error will be worse with the sight mounted that high as opposed to a lower sight mount.  Hope that makes sense to you.
I also have a BSA like in Crosshairs' link with the reversible mount and I like it a lot.
Cheers,

JEBert - That explanation was a big help.  In all the pictures I have seen, the additional converter mounts seem to place the sight very high and while some of my concern was aesthetics, your post helped confirm my suspicion about the negative of it being too high.

I went and ordered the BSA.

Next on the list is barrel and metal band from Mellon.

The problem for a pistol with a Leapers is getting the proper eye relief.  If you decide upon a scope, check out some designed for pistols with around 10" of eye relief.  With CO2, you don't need one that's airgun rated.  In your case, the red dot might be the way to go.  RC

oops, posted same time.  Good luck

hy mate i have an smk scope on with 1 inch diametre  low rise dovetail mounts that fit the 11m rail,pellet loading is easy and the scope is for pistols long eye relief so the pistol can be held well like a pistol should be, 2 x mag exellent for 10-20 meter shooting,you will have to watch the weight though mine is getting a little heavy with the shussy thing on the end

Here is my a 2240 with a 10" barrel and a 2.5x NcStar Pistol Scope. They are pretty inexpensive. I had two of them until a few weeks ago. Another is on my list of have to haves. The make things real nice at 10 meters. I had a BSA RD42, but found it just a tad to large. I might try out one of the 30mm ones someday though. I did like the red dot. Also had a really cheap Daisy red dot for a while and believe it or not, that thing rocked for about 10 bucks. I had a real nicely defined small dot. You results may vary. After you try out a few things, you will learn what works best for you. Everyone likes something and it is not a one size fits all thing. BTW: Welcome to the forum.

^^Thanks arkmaker.  What grips do you have on there?

I just ordered a brake from TKO a few minutes ago.  :)

Those are RB Grips in walnut. I added the inlaid Crosman logo myself. You will like the TKO. Really tames the beast quite well.

That logo looks cool.  I will be looking at RB grips.

Whats the eye relief on these BSA RD's? When used as a pistol configuration?

About 3 inches from the rear lens to as far back as you can see the red dot!

It's 1x (no mag) so there is really no parallax.

Yep - that's what I found when researching the BSA after RC1947's post.  I had no idea what "eye relief" was.  Turns out the Leapers would not have been optimal.

It can be used on a rifle or pistol i have one on each.

  here's what I've done. after modding my 1377 I had a pretty good idea where I wanted to go with my stock 2240. the first thing was to add a long steel breech, then a re-crowned 12" barrel, a heavier hammer spring, longer bolt probe, and put a BSA 30RD red dot on top. All parts are crosman except the R/D to keep my cost down. I buffed out the internal parts with a dremel and tweaked the trigger spring with needle noses. I get quarter size groups at 10m with this set up, I'm satisfied. I get all my parts from ABairguns, they also did the barrel cut down for me, their good folks, and a authorized service center

pirouge,
How is that handling as a pistol with the 12" barrel?  I didn't answer matty's question about barrel length as I don't have one in 12".  I do have a 10" barreled 2300 and am in the process of cutting a 12" barrel for another 2300 but am planning on putting a shoulder stock on it.
Cheers,

Thanks for all the continued input!  The scope arrived but I'm still waiting on the breech from Crosman so hopefully that will arrive next week.

I'm still not decided as to 10 or 12" barrel but I ordered a 5" muzzle brake from tko so I don't want it to be too unbalanced.

I did paint the grips in 2-tone to bide my time while waiting for everything to arrive. :-)

Thanks again for all your help with putting together my first 2240.  All the parts are in and here it is so far...

I think I will eventually get some wood grips but these look ok for now.

I just picked up a red dot BSA sight at Cabelas today for $20.00.  Check your paper or online for the coupon.

Well, I see I'm too late, but anyway... I like 10" best, but 12" bbl gets you a little more velocity.  Metal breeches if you can get short ones it's lighter and looks better, but harder to mount scopes exact.  I've got BSA 2x, Tasco 2x, Burris 3xAO and Phantom II 2.5x on 22xx pistols.  The Burris is the best, heaviest, and most expensive. The BSA 2x is very nice and light.  The Phantom II 2.5x is the lightest, not as good in low light.  I like the Tasco 2x28 Japanese used scopes alot also.  I like lowest rings I can get, wrap over the top style like Airforce, but anything sleek.  Crosman's don't need alot of strength, no recoil.  Lighter is better...  Just what I like.

And anything from TKO, and the AoA HDD hammer debouncer.


Looks like a nice shooter.  I like the two tone grips.

JEbert;   I like the 12" barrel just fine on my 2240, usually I shoot off Caldwell bags @ 10m so weight isn't a problem. The one problem that's common, is I can't carry in a holster with the R/Dot.  Uncle Mike makes a bandoleer rig that works but is bulky, so its a trade off. The 12" definitely increases the range & power, but my reason for the`12" was the ability to shoot heavier pellets in .22 cal. for dumpster rats when I wanted to go "urbane hunting" , it worked, and a 14" barrel would be within reason.
