What do you guys think of a 24” barrel?
Quote from: S2kohio on July 10, 2020, 08:26:13 PMWhat do you guys think of a 24” barrel?As Bill said, this is just my opinion, but it IS based off of some pretty extensive building / modding / testing that I have done on the 13XX and 22XX platforms.I have built several of these guns including mild to moderate 1322 pumpers, as well as 2240/50 Co2 powered pistols to full blown, rear bottled, PCP carbine conversions. In my opinion, (and field testing), you can get to a point of diminishing returns when increasing the barrel lengths on these guns, (relative to the power capacity), of them.IMO, A 1322 built at factory stock to medium power upgrades is best served with a 12" to 14" barrel. Built to MAXIMUM power,... ... meaning, with a flat top piston, modified valve plenum capacity, increased valve exhaust port, extended bolt probe, maxed out transfer port, and modified hammer, .... then you can benefit from a 14" to 18" barrel.24" barrels will only benefit on higher powered PCP conversion builds...... but then again, and as Bill already mentioned, you end up with a ridiculously long "soda straw" gun that is completely unnecessary. Do a search on the forums here for "Lego guns" or "Franken-guns", and you will surely find Dozens of older threads talking about this very subject.Heck, you will probably run into LOTS of my posts from past years on these builds.Good luck on your build and have fun with it.As your first build, I would suggest building it with a Long Steel breech, with 14" barrel, 1399 stock, ice maker tubing transfer port, and an LDC.After you learn that, you can decide how much further you want to take these VERY Fun guns.The Sky, (and your wallet) are really the only limiting factors. Trust me on that. LOL.To give you and idea of just how far you can go...I have built a couple of 22XX based carbines that are pushing just over 40 FPE and will hold "mosh" (Minute Of Squirrel Head) sized groups at 100 yds ! (and that is using a 18" barrel with a 5" LDC ! ! !)Cheers,And Welcome to the Rabbit Hole !There is no turning back now,You have now been infected with the A.A.D.S disease ...and there is no cure.
The stock plastic breech on your 1322, DOES NOT positively secure the barrel from rotation. In other words, the barrel is free to rotate in the breech.This means, that the Transfer Port, (which yours is almost certainly deformed),... (and js now leaking), is the reason your velocity has now been compromised. A Steel Breech literally ELIMINATES any barrel rotation, due to it has 2 "grub screws", (that your stock plastic breech does not have).These 2 additional grub screws, LOCK THE BARREL, and eliminates the possibility of blowing out another Transfer Port... as well as insures that each shot fired, is coming out of a barrel that IS NOT MOVING BETWEEN SHOTS.This is Absolutely VITAL, for accuracy and shot to shot consistency.
Reading all of the suggestions I’m seriously thinking the Crosman custom shop might be my ultimate course of action to get a new 1322 with a steel breech, 14.5” barrel. But then the questions. 1. I like the iron sights on my 1377. It was straight when I got it. Shoot dead on. If I get the steel breech on the 1332 I see I lose the built in iron sights and have to use scope or red dot or buy iron sights. I bought 2 scopes $30 each at Walmart and have never been able to zero them. You get what you pay for. I also have a $30 BSA Red Dot. The red dot seems to hold zero but I like the iron sight better. I’m posting at 30 feet so in reality the iron sights are fine. So if I go with steel breech I can again try to zero the scopes (which I’m sure will be as crappy as before) and the BSA. But what iron sights should I buy?2. I see that there are 2 types of barrels. Again, I’m just pesting at About 30 feet, so I don’t see the value of an LW barrel at $40+ more dollars. Please educate me on that. 3. What’s an air stripper? What does it do? I also don’t see that option on the custom shop. 4. Where do I find the folding stock (I have the 1399 with quick release pin). How much is it?5. I do see the benefit of the longer steel breech, which is what I would get.
IIRC, you can get a 10" barrel from Crosman Parts for very cheap I'm sure someone here can provide the part number for that.

But if you are purchasing a barrel just order a custom shop 2400kt and make yourself a pumper or use CO2 for summer pesting.2289-001= 14" .22 barrel2260-003= 24" .22 barrel2260SE-001= 24" .22 Disco Barrel1760SE-001= 24" .177 Disco Barrel
