Crosman Scope Mounts (Set of 2)

(27 customer reviews)


Clamping Optics Mount for Crosman Airguns

  • 21mm weaver or 3/8″ dovetail
  • 3D printed in the USA in Texas
  • Compatible with any unobstructed 7/16″ Barrel
  • Made to be Self-Centering on the Crosman 1322, 1377, 2240, and 2260
  • Replaces the Crosman 459MT Intermount
  • FREE Shipping to anywhere in the US


Use this mount to add a scope, red dot, or other optic to many airguns that use a 7/16″ barrel. You can select either a 3/8″ dovetail mount or a 21mm weaver mount when checking out.

Much like the Crosman 459MT Intermount, it is compatible with quite a few Crosman airguns. With the 1322, 1377, 2240, and 2260 it is self-centering. Since it is made from plastic it clutches the barrel very firmly without scratching or damaging it. It uses 2 screws to clamp on to a 7/16″ airgun barrel for a firm grip. Instead of using only one screw threaded into aluminum, this clamp uses two 18-8 Stainless Steel screws threaded into flush-mounted stainless nuts.

Included in the package will be 2 mounts(4 pieces), 4 stainless steel socket cap screws with nuts, and a hex wrench for installation.

Many customers have asked if it is compatible with older model 13XXs. I have had a few customers with 1377s from the late 1970s and early 80s use this mount on their airguns after removing the spacer between the barrel and pump tube.

    I love your crosman 1377 scope mounts..they fit perfectly on my gun made accuracy perfect…they are awesome..keep up the great work…i will be ordering more items..highly recommend…love the thank you note. Speedy delivery too. Thank you

  2. Ben Myers (verified owner)

    I used these to put a red dot on my 1322 and they work perfectly. The design is awesome and much improved over the crosman version (which you can’t get in a weaver version). Shipping was very fast and I couldn’t be happier. Great company to do business with, hope they come out with more 1322 products!

  3. Todd R. (verified owner)

    Without question, these are the BEST scope mounts for the Crosman 1377 on the market!! These grip the barrel and don’t let go. My scope is rock solid with these mounts!

    If you’re undecided whether or not you should get these or the Crosman 459MT mounts, don’t even think twice. My first go around I went with the Crosman mounts and no matter how much you try to tighten those mounts, it still wobbles. The screws will strip if you try to tighten them too much. Mine did. Rest assured you will not go wrong with the mounts from from Buck Rail!!

    Outstanding product at a very reasonable cost. Family-owned and operated; a big ups to the thank you note from the kiddos 🙂

    quick shipping, 10/10 what more could you ask for?

    Ten stars. I went down a rabbit hole looking for the right scope for a 1377, opinions all over the board, and all I needed was to remove some aggressive sparrows that were harassing our purple martins. And then I stumbled across Buck-Rail. I was impressed with the installation video and thought the 3D printing would yield a good fit. YES it did. This plus the Hawkeye sight really upped my game and for much less than other options. Thanks Buck Rail.

    Vary good mounts, I put them on my 1322. I’m going to get a 1377 next, I’ll be back for another set for it.

  7. Jed Paul

    Very solid mount, a vast improvement over the Crosman mounts. No movement of optics. Now just need to sight in and go shooting.

  8. Andre Thomas (verified owner)

    I’m extremely satisfied with your scope mounts. At first, I was cautious and ordered only one dovetail and 2 Weaver mounts.

    These items arrived promptly via U.S. Postal Service.

    I installed the Weaver mount first. Everything went fast and simple. Zeroing in my red dot was no problem with these mounts…and has maintained zero to this day. The fit, finish and build quality is very good. Properly installed, these mounts will do the job.

    In conclusion, I’ll simply state that I ordered more Weaver mounts for myself and for gifts.

    The Best mounting system for the 137u or 1322. Don’t let the plastic dissuade you -it’s super strong and holds zero perfectly without adding weight. The value of the product exceeded my expectations to the point that I’d happily pay twice as much for such a stellar product from a great family business. Be sure to check out the vids on mounting as I did before buying and you’ll see how good these little rails are for yourself. Thanks, Buck-Rail, for such a great, lightweight mount!

  10. Jason H.

    I first bought Crosman 459MT Intermount – it’s so unstable and causing barrel movements all the time – completely useless.

    Then I found Buck-Rail and this wonderful replacement! It’s very well designed. Not only it’s a great mount, but also serves as a spacer between barrel and the main tube. Now my mounted scope is rock solid. This is truly one of a kind product.

    Fast reply to email, fast shipping, great guy and great part

  12. JT (verified owner)

    Fast service and great craftsmanship! Crosman mounts are garbage compared to these. Btw….cute note. Thanks

  13. Jan Duivestein

    Terry thanks
    For the fast delivery of the mounts. (To the Netherlands) They are much better than the Crosman 459MT mounts

  14. Big J’s Outdoors & Airguns (verified owner)

    An amazing product at an amazing price! Made it possible to mount a scope on my 1377 and maintain accuracy. No more barrel flopping around. Can’t recommend these enough! Thank you!

  15. Wendell (verified owner)

    Got these today, and they make for a solid mount! Unlike the Crosman 459 mounts, these have a radius that SITS on the pump tube, preventing the barrel from twists and turns. Well worth the money! Thanks!

  16. Rob (verified owner)

    Excellent product! Solid mount, no play at all. Fast delivery and can’t beat the price.

  17. billy andrews (verified owner)

    just got my mounts yesterday in the mail , so i haven’t had a chance yet to install on my 1377 . think i will wait until i get my stock done and reblue my barrel before I do it

  18. Russell Wallace (verified owner)

    Received my mounts for my .177 pistol Monday 1wk from ordering. Fast shipping and GREAT set of mounts. Solid on barrel perfectly made with correct angle on bottom to contact metal pump tube from both sides. Great detail. Got the dove tail for a 6$ scope at Walmart and shooting 5 shot groups in a dime @ 50’ can’t wait to get outside.

  19. Hank (verified owner)

    Works as intended and delivered promptly.

  20. Edward (verified owner)

    I purchased the picatinny style for my
    1377. Installed in minutes an very pleased how solid these are. Shot 5 pellets with a new dot style scope an dead center bullseye. Very nice very happy. Thanks

  21. James Johnson (verified owner)

    I ordered the 21w mounts (2) for the Crosman 2240 .22 pellet pistol. Gun ranges are still closed here and it was easy to set up an inexpensive 10 meter range in my basement. I’ll be 75 on the 14th and my eyes tire easily. My range guns use scopes and a couple Red Dots to be more accurate. One buck-rail mount fits perfectly on the Sig Sauer Romeo5 Red Dot and I’ll save the second mount for the Crosman 2300T once they’re back in stock. Very nice product and delivery was on time. Thank you!

  22. Michael Gentry

    For the Crosman P1377BR American Classic
    Ordered the Clamping Optics Mount and reflex sight package deal
    It fits perfectly and securely. I looked all over the net and YT for something that looked to have quality. This did! I’m very pleased with the perches.

  23. Carl (verified owner)

    i got these mounts to replace the 459 crosman mounts on my 1322. they fit a lot better and were more than up to the task for holding a 4×32 short scope . they are rock solid and do not move even with a good amount of pressure applied to the scope. nice product i am glad i found this site.

  24. Doug Downie (verified owner)

    Works great,fast delivery. Support a small American business and build up your 1322/77.

  25. Chris (verified owner)

    Self Centering, sturdy, looks good. Delivery was fast. What else do you want for around 12 bucks? Would definately buy again.

  26. Eugene Adelman (verified owner)
