Crosman M4-177 Suppressor Kit

  • Adapter replaces stock muzzle cover. Only requires removal of two phillips screws
  • Threaded design allows easy removal/installation of suppressor
  • 3d printed with ABS in the US by a veteran-owned business
  • FREE Shipping within USA. Ships same or next business day via USPS.

****PLEASE READ THE FULL DESCRIPTION BELOW!****

This suppressor was designed exclusively for the Crosman M4-177. The adapter replaces the stock faux flash suppressor at the end of the muzzle. It is threaded to accept either the included faux air stripper or the suppressor. The adapter features a top and bottom picatinny mount, allowing you to still mount the front “iron” sight, flashlight, laser, bipod, etc. The suppressor uses a 7 cone-shaped baffle design. It is 3d printed in the USA using ABS plastic by a veteran/family-owned business.

To install:

  1. Remove the two small phillips screws that retain the stock muzzle end cover thingymajiggy.
  2. Remove the stock muzzle end cover thingymajiggy by sliding it off of the end of the barrel.
  3. Slide the adapter onto the end of the barrel.
  4. Align the two tabs to slide in between the stock brackets(There is no top or bottom).
  5. Slide the adapter in until the screw holes are aligned.
  6. Reinstall the two screws using a small phillips screwdriver. Do not over-tighten.
  7. If you are installing the suppressor just remove the cap on the end of the adapter by turning it counter-clockwise then thread on the suppressor by aligning it on the adapter and threading it on by turning it clockwise.

Note: If you experience a decrease in accuracy you can drill out the baffle inner diameter larger and larger until you get the result you want. Uninstall the suppressor before you do so, though.

Thanks for lookin’!

    Absolutely no sound coming from the barrel anymore. All you hear is the action of the gun and the BB hitting the target. Very backyard friendly for sound. Unfortunately it looks even more badass and may scare anyone who gets a glimpse of it through the fence hedge. It will have to stay in my basement shooting range. I noticed an improvement in BB accuracy. This gun is accurate with pellets but not so much with BB, but I think this suppressor settled the BB a bit and is a little more accurate now. I only use this with BB, so more accuracy with BB is helpful. Love the way it looks now.

    I had a small problem with the adapter that I mention off-hand in an email to Chris at Buck Rail. By return email the same day he (without me even asking) offered to replace the adapter. When I accepted his offer, he had the new one in the mail the same day. Not only that, but he kept me informed about the status it's status, even sending me an email when he knew it was out for delivery by the U.S. Post Office. You can not ask for better service. Thanks Chris!!!

    Fits perfectly. This item definitely on par with the 3-4 accessories I’ve gotten from Buck Rail. I can also verify that the customer service has been top notch. Better than any company I purchase from (and I seem to buy a lot of stuff). Personal responses and fast resolution. Free shipping, great prices, that’s it! I need more guns. Thanks Buck Rail!

    Very nice 3d printed 2 piece set that perfectly fits my airgun. Very easy to install, don't even need instructions. The silencer makes a noticeable difference in the sound it makes and is overall quieter. Shipping was fast and I think the price for the parts was more than fair.

    Easy to install and to remove . Definitely worth the money the look is good to and definitely sound reduction

    Worst quality 3d printing scuffs and markings all over almost broke my m4 .177 trying to pull it off thanks. also will not shoot properly the bb/ pellet will bounce off the walls of the "silencer". Actually called a suppressor it suppresses sound not silences.

    This customer never contacted me with his/her concerns. I’m always happy to replace parts or refund folks who aren’t satisfied with our products. In fact, I even refunded this discontented individual after approving this review. I can fix the the problems I know about and will always be quick to do that. I’ll even do it with a smile on my face! In other news, there’s little hope for humanity...
