UPDATE 1/25/2021: These are currently out of stock! I’m mildly confident that I’ll have more ready in a week. I will post in my BLOG when they are back in stock. If you are subscribed you will be notified by email. Thank you for your patience!

This listing is for a threaded adapter, suppressor, and thread protector for the Crosman 1377 or 1322 airgun. The suppressor has an expansion chamber and 8 cone-shaped interior baffles that significantly reduce the report of this airgun. The suppressor can be easily removed by unthreading it by hand. A cap is provided to protect the threads when the suppressor is not in use. To install you will need to remove the spring roll pin that secures the pump arm and end cap, replace the end cap with the adapter, and reinstall the roll pin.

The adapter is printed in super tough PA12 Nylon by another manufacturer in the US. They use Multi Jet Fusion to print the part and bead blast it to give it a nice finish. I 3d print the Suppressor and Cap in ABS at my home in Texas.

    First of all, my order was shipped out the same day I placed it so that’s excellent!

    TLDR: the parts are an excellent fit, well printed and finished, and provide excellent sound reduction. Near 10db measured by me (phone app). The terms “moderator” and “ldc” are used interchangeably.

    The replacement threaded nylon barrel bushing / pump piece is very well done. I have a few 3d printed items and this part looks and feels injection molded; no seams to speak of. The fit with stock parts is better than the original Crosman part and is very rigid. A great choice for those looking to add a moderator to this short barrel. Competitive metal pieces cost $70 plus so this is a no brainer part.

    One thing I don’t know, due to inexperience, is if this part is threaded 1/2×20 unf to accept other ldc. Though I don’t know why you would bother with the performance of the stock ldc.

    The ABS moderator itself:
    Straight and threaded perfectly for the male part on the gun. Obvious print lines are present but at 1 foot away you can’t tell; it’s nothing some 500 grit and a rattle can can’t overcome. The ABS is much stronger than I had anticipated and feels quite durable. No defects or baffle issues detected upon testing. New iron sights are useable with this set-up.

    Total sound reduction: On 3 and 6 pumps is 10-15db with an android app. This was with 14.3 and 17gr projectiles. Noise reduction is significant to the point where target impact noise is louder. This is now 100% backyard friendly minus the space-gat look. I’m really happy with it.

    Time will tell on some of the fittings and overall wear and tear but initial quality for $25 is through the roof. A great set of items that over-provide the advertised function and over deliver on quality.

    I will be back for more!

      Thank you very much for the feedback. Lots of good info there. The threads are M20x2.0. So not compatible with any suppressors that I know of. I tried 1/2-20 at first, but they were not a great fit for plastic parts. Our 1/2-20 suppressor threads are reinforced with a stainless steel helical insert and intended for steel threaded muzzles and adapters, but these are plastic to plastic so I wanted something larger and more coarse. Our m4-177, 1077, 880, and 13XX suppressor adapters all utilize the same threads and suppressors. Thank you for your business and thanks for the support! P.S. Space-Gats are totally backyard friendly…;P

    Received it this morning and I’m very impressed!
    Very sturdy, a bigger, robust front sight/barrel band ,thread size is bigger than 1/2-20 and that’s fine.
    LDC interchangeable with included thread protector (aka FLASH HIDER!) this is a Super set up, and makes my 1377 RC very quiet.

  3. Dennis (verified owner)

    This is a MUST HAVE accessory for the Crosman 13XX series guns.

    Much better than the previous version. Oversized baffles prevent pellet strikes internally. Does a nice job making things quieter. When I shoot a sparrow or a starling from 15 yards or so, the other birds sometimes don’t even take off. They never know what hit ’em!

    I bought two, one for a 1990’s 1377 and the other for a newer 2021 1322. Both fit a little loose on the end of barrel, but I wrapped some aluminum tape on the barrel and that snugged it up. On the 1322 the front post sight was too low (I’m using the peep sight and this might not be an issue with open sights) so I super glued a 3/32 high piece to it and that worked great. The issues I had aren’t that bad if you don’t mind tweaking it some. The silencer it self works GREAT with very goo sound reduction!!!

  6. Jeffery Sullivan (verified owner)

    I just spent a half hour testing this “silencer” on my 1377 and there is a definite noise reduction. That is AWESOME for my purposes. I’m working to make my 1377 a good “backyard gun” with as few mods as possible and this is definitely a step in the right direction.

    With the thread protector on, there is virtually no change in sight picture. However, the sight post shortens a little with the suppressor attached. After a couple minutes, I was used to it and was still getting good “angle of coke can” accuracy.

    Having said that, I’m looking for much better accuracy, so my next step will be to find a quality, easy, small optic to get well over the suppressor and tighten up my groups.

    Also, I purchased this as part of a much bigger order as I have some other projects working too. I’ve seen a few folks ask about the threads on the suppressors and, given that I ordered one for another gun and they appear to be interchangeable, I’m *guessing* that the threads are standard across all the Buck-Rail suppressors. That’s a very good thing.

    • Terry (verified owner)

      Jeff, thanks for the feedback. It should be pretty easy to make the front sight post taller. I’ll do that on our next batch.

  7. Ray

    Terry, I like your products. Looking forward to the taller front sight version. When are you going to release it for the 1377/1322?

    • Terry (verified owner)

      Thank you for the feedback. It’s now available with a taller front sight post!

  8. Ray

    Terry, this is exciting news. Just wanted to be sure, is this new taller front sight actually taller than Crosman’s stock front sight on 1377? I have an LPA MIM rear sight and the gun shoots high, so I wanted a taller front sight than the stock one. If I order now, you’ll ship the new version by default right? Thank you!

    Just finished the install. No problem removing the roller pin. Just watch the video. Sound reduction is really real. Weight increase is negligible. I have a Red Dot behind the loading breech so the front sight is a non-issue for me. No louder than my old Daisy Red Ryder! Great design job.

  10. Jeffery Sullivan (verified owner)

    This review is an UPDATE to my earlier purchase. When the upgraded suppressor with the taller front sight came out, I had to try it and it is Lovely!

    I just got done installing the new front sight and a replacement roll pin and took out 5 cans at about 14 yards no problem using the new front sight coupled with a replacement peep sight I found on ebay. I’ll do some actual target work when it’s light out and warmer, but easy “angle of coke can” now. Thanks Terry!

    I own the P1322 and wanted to practice in the basement at 120 meters. Wifey was upset that she could hear the report from the pistol. I ordered the P1322 Suppressor and wow, what an improvement. I downloaded a dB meter for my iphone and it recorded a 12dB reduction with empty chamber firing. All I hear now is the whack of the pellet on the target. This is an essential product to ensure you have a great shooting experience.
    Cannot be happier with the build quality, speed of service, and great communication. This is an outstanding product at a very fair price.

    great people great product great price

  13. b65445 (verified owner)

    This is nothing short of excellent! I got it within a week of ordering, and the parts have a very surprisingly snug lockup and fit quite nicely. I was expecting some noise reduction of course, but I wasn’t expecting it to be this quiet. It was perfectly aligned the moment it was installed and didn’t hinder accuracy at all. The little flash hider is a nice bonus as well, and for $25 I’d definitely recommend this little suppressor.

  14. Michael Fitzgerald (verified owner)

    Only one word to describe this suppressor is needed, awesome 😎 this is a need not a want, you need this, I am still amazed at how quiet 🤫 it is, the owner is awesome, shipping was fast, overall I have absolutely no complaints, I am more than satisfied and will definitely buy more for my 1377 from this site

  15. Joshua Barry (verified owner)

    Couldn’t be happier with this product. The stock barrel bands on the 13xx series are begging for an upgrade. These not only look and feel more secure, the bonus of a threaded adapter is icing on the cake. I’ve been building and testing a 1377 in my urban backyard. The report is almost non existing with the silencer.
    Amazing design, amazing product.
    Amazing company.

    I was looking hard for something to suppress my 2240 Crosman and my Crosman 1322 and I came across this site veteran owed plus! The delivery came promptly and was amazed at the quality and the ease of installation as well as the device working the way it was intended to work at a good price point. All great things if your on the fence just pull the trigger no pun intended! Lol!!!😁

  17. Steve (verified owner)

    Got this yesterday and after installing it went out back to try it out. Wow! At 10 pumps this pellet gun makes less noise than it did at 2 pumps without it.

  18. jeregosh (verified owner)

    I ordered on Friday and received today – Monday! 1 business day!! Installed, tested and immediately drawn to say this is legit. Fit, finish, performance, ease of install, and VALUE – all excellent!! So glad I found this site. Thank you!!!

  19. Randy Evans (verified owner)

    Wow! Easy install took less then 5 minutes. Love the silencer. Works great. Knocks noise down at least 10 to 15 decibels. The flash suppressor that came with it as a thread protector aesthetically adds realism to the gun when it was on. Could not decide which to use at first I liked the looks so much. Ended up using silencer for neighbors sake. lol

  20. Eric Thorsell (verified owner)

    Bought this and the plumper pumper for my 1322. Install is super simple and straight forward. Noticeably quieter and I think I picked up a couple more fps and my 25 yard grouping is a little tighter. My 1322 is way sexier now too and let’s be honest, isn’t that what it’s all about????

  21. Klaas Jan (verified owner)

    Great silencer! Fits very well and installing it was easy. I am very happy with it. It gives the gun a better look and my impression is that the silencer does a nice job reducing some noise. Got it within 3 weeks (Netherlands!), and that’s not bad, because it took 4 days customs clearance. Highly recommended!

  22. Tommy Davis (verified owner)

    A definite must have for the 1322. Surprisingly effective. Even at 10 pumps, it’s quiet enough to not disturb the neighbors at all. Actually with this suppressor on, it isn’t much louder firing than it is dry firing with zero pumps. The pellet hitting the target is louder. Everything feels very well made too, and fit well. Will definitely recommend this item.
