Crosman .177-Cal Steel Breech Kit Reviews

First off the Website is very well put together and very easy navigate. My item was as advertised and very well packaged. Item also shipped out fast and item delivered on time

Honestly nothing in my opinion

Yes check out there refurbished section to find great deals on used items

Great product Adds Mutch better accuracy to an already accurate pistol_ rifle. easy to install

pay a little more attention to manufacturing as the transfer port didn't line up & had to file off about 1/32 nd of an inch to get it to fit. the barrel was purchased from CROSSMAN directly so there not to blame.

I rolled the barrel with my left hand on my lap while holding a mill file with my right 3 or 4 minutes later it fit nicely. same thing with the loading area inside the barrel; cone shaped Dremel bit works nicely. despite this its still a good product more solid than others I've tried.

everything fits many different air guns finish matched every Crosman air gun I've put them on.

pay a little mor attention to manufacturing tolerances. I had to file 1.6 mm of a Crosman barrel before the transfer port would line up and the bolt would close.

converted a Crosman 362 into a 177 Cal rifle with this one & it upped the velocity to 977 fps with a 7 gr wadcutter just what I wanted. now I'll go to the 10.5 s for accuracy. should bring the fps down to the 800s perfect for some target work (found a 3x9x40 hammers online why doesn't PA sell them their awesome possum scopes

will fit on my Crosman 362 perfectly.

include breach screw washers so the pellet wont catch & mangle the head of the pellet

I'm transforming a 362 into a 177 Cal hoping for awesome speed increase. bought a 177 Cal barrel from Crossman put a washer behind the hammer spring & pump it up 15 times yea it will work without saving any air. (lets call this one a 367 ? rats i should have patented that. next epoxy that transfer port bushing in place you're losing a lot of air right there PS I always file out those transfer ports for max power

Great product works like it should. finish matches up nicely with gun finish.

should come with breach screw washers as standard items. pellets will catch sometimes in that area.

Dennis at baker air sent me breach screw washers free as I buy lots of stuff from him. If the bolt handle is loose turn bolt probe 180 degrees & reinstall handle that will more than likely fix it.these also fit the Crossman 362 pump rifles same platform as the 1322 1377 pistols

It was pretty simple to install and it really changed the character of the gun. Everything feels much tighter and more solid now. Accuracy seems to have improved as well although that could be because of the dovetail sight that this breech can accept.

The bolt handle needed a little filing to properly fit. Not a big deal.

It does add noticable weight

This is far more secure than the plastic breech.

The breech screw - the head of the small breech screw sits in a large counter bore that pellets fall in. This makes them harder to get into the chamber without damaging. (This has not been a problem for me on the .22 version).

Just what I wanted. Excellent quality. Very happy.

The steel breech is more rigid than the plastic one, and has more support surface for the barrel.

The undercut on the breech is contoured 2240/1740 tube. The 1377/1322 tube is slightly smaller in diameter. It still tightens down, but the tolerance is kind of sloppy. I wish they would make one specifically for the 1377/1322

The O-Ring on the bolt probe seems to ship dry. Oil it as detailed in the airgun's owners manual to prolong the life of the seal.

Steel, nice weight and good finish. Secures very nicely and was easy to install after some fiddling even without looking at instructions(do still look at instructions there's no reason not to).

Blue loctite on the bolt handle threads but you can do it yourself quite easy and loctite is always good to have around anyways, it'll just come loose after working the action a few times(or maybe I'm just rough).

This with the stock makes for a very accurate little plinker.

The option for a scope or red dot sight. Easy to install. You can also add an adjustable open rear sight.

The addition of sights with the rail. Better screw placement.

Overall very pleased with the whole set up. I will be adding another one to my next one.

Steel is way better than plastic. Holds the barrel much better

That dang screw that sits to low that causes pellets to get jammed or go wonky when loading them. I know there are aftermarket solutions, but crossman should really fix this (Maybe they have, but just want to sell out all there old steel breaches?)

It's heavier than the plastic, but I personally think that is a good thing.

Everything.

I would make this the factory installed breech and never, ever subject another customer to the worthless plastic breech that is the current standard.

It is worth the upgrade.

Great product, but I do it consider this an upgrade it's more of a retro part in order to utilize optics. The plastic breech is good and has no problems loading pellets. But with the steel breech a washer must be used to raise the breech screw in order to eliminate the pellets from jamming. The paper washer is the way I fixed the pellet jamming problem. Also the paper washer cost nothing, just take your time and cut some hard paper and problem solved.

I would add some paper washers in the breech kit.

Pellet jam occurs with this retro/upgrade.

This gives you the ability to mount optics on your 1377. It improves and already accurate pistol. I think it makes pumping the gun easier as it stiffens the overall barrel breech connection. The pistol feels a lot more robust.

The biggest issue with this kit is that breech screw hole. The pellet will hang up and requires a lot of work to load properly. Crosman has know about this issue forever and just cannot seem to figure out how to include a simple nylon washer/spacers (like 3 cents guys- come on!) I was frustrated that they cannot include a slightly longer rear mount screw so the original sight can be utilized. (ok another 3 cents- but I would have GLADLY paid an extra quarter for those parts!) The barrel grub screw is WAY too long for the 1377 application and my dovetail to Weaver adapter had to be mounted in a way to accommodate the grub screw sticking up (I am going to find a shorter one in my screw collection and replace it. Crosman put lock tight on every screw EXCEPT the bolt handle threads (the one screw that actually NEEDS locktite)

This takes your 1377 from a cheap beginner pistol, to a serious contender. Yes it is expensive (taking the price of the gun to the $100 dollar range) but it makes a difference in what can be done. Be aware the directions are for the 22xx/23xx series and not really user friendly for the 13xx series. My transfer hort fell out and I had a Heck if a time figuring out which end went up (it only fits properly one way). You cannot reuse the stock sight as the included (and original screw are too short. The barrel band on the new version of the 1377 does not need to be loosened (it can't be loosened) and you need to remove the lower tube hammerspring retaining plug (and the spring will fall out). This is challenging to replace as you need to compress the spring and line up the cap holes AND start the screw! I'm not a beginner when it comes to airguns, but this took me about 45 minutes to complete (from removing the old breech to a completed project.

Another satisfied customer!

Nothing

Youll enjoy the upgrade.

I fits and the steel barrel makes this 1377 pistol manageable. The plastic breech that was on the pistol was not very good at all.

Chromed breech would have made this perfect.

Easy install took about 5-10 minutes

Has places to mount scope rings.

Rear sight doesn't match front blade width. Make rear sight viewing notch narrower. Peep sight was better.

I needed to glue thin pieces of plastic to both sides of front sight blade to make it a closer match with rear sight notch.

The breach makes it compatible for scope mounts.

Pellets seem to hang up in the counter sunk breach mounting screw hole.

All good

There is nothing to change.

First modification on 1377 ,you guys know sky is the limit on the C.C.
