And thankfully I was able to get it out!
I was changing the probe in my 1377 and torqued a bit hard... and that was the end of it.
Guess I'll be calling Crosman tomorrow. I hope they have a few in stock. Maybe should get some spares.
Part number is 1322B027 and they are $1.50 apiece. You can get a better deal on screws at McMaster-Carr but a different screw entirely that you will need to mod.
Incidentally the screw is a 4-48 x 1/4" long.

I think everyone on this forum has probably done that.
Don Cothran has really nice stainless steel screws that seem almost impossible to strip. Other guys sell entire sets that have stronger replacement screws for the whole gun...don't have anyone to give you though, maybe someone here will.
I already had the part # looked up. $1.50 isn't a bad price. Might as well get a few spares.
They should have them the next time you take your breech off rember the breech screw goes in first and out last seems like the big screw some times will move the breech and you have problems. Taking the big one out first gives you a better shot with the little one also when removing it squeeze the barrel and tube together hope this helps you out :-*

I stripped the hex out on one yesterday, had to drill the head off. Luckily I had a couple spares.

Thanks for the replies. I am still a newb when working on these pistols, although I am learning a lot.

Almost all of us can truthfully say, "Been there, done that!"
And you would think that we have all learned, but it still happens once in a while. :-[
Carl
Check on eBay for accustom breech screws got some the other day and much better than the Crosman ones.
Yep, I learned that one the hard way too...
Good advice from brz-ryder and I apply some clamping pressure too until the screw breaks free
also make sure you have a good 0.050 allen key it should fit real tight in the head
forget crosman get these

+1 on that... I ordered a boat load of those last week...
Much thanks for the tip guys.....just ordered some :-*
;D ... Stripping the breech screw is ... well ... sorta like a right of passage ...
into the Crosmaniac kingdom so to speak .... :-*

To receive full rite of passage one must also complete the following:
- lose your detent ball
- shoot your Chrony

Oh yes, I have done both of those several times. My one chrony got so bad I finally had to buy a replacement. It looked like it had been to Viet Nam with me.
Carl
My Chrony was shot by a friend of mine with a .45 colt. It cost $60 and postage to get it fixed.
looks like i've just got to lose the detent ball then i'll i be a fully paid up member of the club
luckily gary sent me some when i got some breech screws of him recently

I have a stripped grip bolt on my 1399 stock >:( I have been struggling with it for days!!! I was using a hex bit to tighten and it snapped, I have broken 7 drill bits so far... I'm trying not to destroy the stock but I might have no choice. I have given up for now...

how in the heck did you tighten it? why so much force? :P
is the broken bit still in the stripped hole?
you might have to drill next to it around it pop the broken bit out then still down
lets see a pic of this project
Try cutting a slot in the screw head for a screwdriver with a dremel and a cut-off wheel. Worse thing that could happen is your slot will extend onto the stock a little way on each side of the screw hole.
Good luck,
I called Crosman this morning and much to my amazement, I spoke to a real human. I ordered 4 screws right away, so at least I have spares.

Yah... that IS nice :-* :)
I have a great tip that I read somewhere about getting a stripped breech screw out. First make sure that your rear breech screw is in tight, then you take a size T6 torx bit (star drive) and drive the bit into the tiny breech screw hole with a small hammer, slide your bit driver onto the bit and you SHOULD be able to unscrew it no problem.
The first screw that I stripped I did not know this tip and used a hand drill to drill it out making a big mess and sweating bullets the whole time, and to think I still stripped another screw out after all that! ???

That IS a good tip! Thanks!!
Someone also suggested using a clamp like the one pictured to clamp the breech and tube together removing some of the pressure on the screw thus making it easier to remove.
Also works for putting it back together. But then you definitely need to remember this when taking the gun apart again.

That's the method I use too, saves a load of bother, Plus remembering not to ever put a hex head breech screw back in again.
The one and only time I stripped one was because I forgot to apply the C-clamp before trying to remove the screw. It never happened again because I immediately replaced the screws in all my guns with SS philips head 4-48 1/4" screws. I used a drill to remove the top of the stripped screw.
I also use some light weight oil on the breech screw threads before I install the screw and clamping pressure really helps against the resistance of the TP sleeve on the square oring....

I've taken the plastic breech off my BackPacker (and put it back on) once in the past and fortunately managed to do so without stripping the hex head of the breech screw. To be honest, I can't remember if I removed the large screw (at the rear of the breech) first or not. If I'm reading the slightly confusing and TOTALLY UNPUNCTUATED reply quoted above, that would be the proper way. BUT, I have seen a video and a comment in another post that shows/describes the opposite sequence to be the prefered method. I'd like to avoid stripping out the screw head. What is the best sequence to disassemble this area of a 13xx/22xx airgun? Thanks. Flex
For what it's worth, I always put the breech screw in first and take it out last. Has always worked for me.

Thanks for the quick reply. My nature compells me to ask tho, why you put re-assembly BEFORE dis-assembly. ??? Didn't you have to take the screw out before you put it back in? ;) My wife always gets PO'd when I ask this kind of thing. I guess it's just part of falling under the sign of Virgo :). Flex

Easiest answer is because I keep all my guns disassembled and only assemble them when I'm ready to shoot a competition.
Second answer is because I am anal.
The third and final answer is what difference does it really make? :D

Do you get a discount when you buy your guns disassembled? ;D I'm clearly not ready for that discount. But I guess maybe I should strive for that :D ;) Flex

Thats pretty reasonable for some of us maniacs :o
I usually just end up replacing the breech screws with 6x32 button head screws... I learned with my disco which has the same tiny #4 screw that they are just way to easy to strip.... so I picked up a handful of the 6x32 button heads in stainless.... simple matter to retap the hole on the tube, don't even need to drill a fresh hole just start our tap in the hole that's there... its big enough it will recut perfect threads. You then need to hit the breech hole with a #27 drill bit and then turn the head of the screw down a touch and/or open the couterbore of the hole up a bit..... I usualy turn the screw head down to about .214 and then use a 7/32 (.2188) bit that I ground the face flat (or a 7/32 end mill if you have one lol) to counterbore the hole....
never strip a breech screw again and holds MUCH nicer...... combine that with clamping the breech for assembly/disassembly and life is a lot easier
how do pellets load michael i'm finding with the slotted csk screws that they dont fill the hole properly and the pellet tends to tip because of it
sounds a good soloution as the standard ones are too small especially if your on hpa
ped
You can always put a drop of melted black Crayon or hot glue or sealing wax in the screw hole to smooth out the passage.

the button heads I have are hex key... and though not as flat as the stock screw is it doesn't seem to give me to many hassles.... but then again when I am loading I usually drop the pellet down the bore anyways and just use the bolt to seat it... I so seldom ley the pellet into the breech and close the bolt that I honestly don't remember IF it causes problems loading LOL
cheers micheal i'm going to try carls idea with the wax as its on one of my pesting rifles and sometimes dropping the muzzle to allow you to drop the pellet into the leade is not always possible
my other option is to swap to a hollow probe as i'm only having this problem with the pin probe

Yeah mine too..I had ss domehead allen screws that utilize 2mm allen keys lathed for my 3 Crosmans.

looks good senor crossliner i 've got one 2250 that has a m4 screw in but i machined the head to fit a normal breech i think i'm going to mod a breech to take a larger csk screw for my hpa rifles

Thanks Herr P...Yes that be be the right move if you elevate to a more potent powerplant.
