Benelli M4 6 Position Recoil Tube Specs:

  • Rx Arms Benelli M4 6 Position Recoil Tube is designed and tested for the Benelli M4 and M1014, with the OEM Collapsible Stock (70085).
  • Material: Rx Arms Benelli M4 6 Position Recoil Tube is CNC precision made from 4140 Hardened Steel bar stock.  After machining, the parts are then sent for computer precision heat treating on the notches.  This brings the sub surface hardness of the notches as high as 52-55RC.  This reduces peening or damage on the notches from firing the gun, or from butt stock strikes.
  • The finish is a custom Aluminum Titanium Nitride (AlTiN) PVD surface finish.
  • Engraved stock positions for easy reference of preferred stock length of pull.
  • Machined to resist side to side play in the buttstock when set in position.
  • Includes a retaining flex ring pre installed in the tube. Made from Stainless 302.
    • DOES NOT INCLUDE: Recoil spring, Spring Plunger, Spring Tube Nut, Stock Retaining Screw, Stock retaining screw ring spring.  These items need to be swapped from your original recoil tube.

Benelli M4 6 Position Recoil Tube Installation Instructions:

OEM Benelli M4 Recoil Tube (Benelli 70130, Benelli 70043) Benelli M4 Collapsible Stock Length Of Pull

The OEM stock Benelli M4 recoil tube for the Benelli M4 Collapsible Stock has limited length of pull (LOP).

  • Position “1” with Benelli M4 Collapsible Stock, is too short to be practical for real world use.  Measuring at 9 3/8″ LOP. The only use for this position is storage.
  • Position “2”, or the mid way point, is around 12 3/8″ LOP.  This can be a good length when wearing some thicker clothing, but for the majority, it is usually too short for thin cloths.
  • Position “3” with the Benelli M4 Collapsible Stock jumps to 14 1/4″ LOP.  This length can be too long for shorter to average height shooters.  In reality, most shooters would prefer a length of pull in the middle.  This is where the Benelli M4 6 Position Recoil Tube comes in.

  1. Gary (verified owner)

    Design features and finish are a considerable improvement over the stock M4 recoil tube. This purchase for me was an absolute no-brainer.

  2. Noe Z. (verified owner)

    Solid part and functions flawlessly.

  3. Ryan (verified owner)

    I’ve had it for about 4 months now and it’s held up just fine. It seems to be really well made and it’s helpful to have engravings for different positions

  4. Brian H. (verified owner)

    Arrived quick and very happy with it. You can tell it’s a high quality product and works great with my m4!

  5. xing C. (verified owner)


  6. David H. (verified owner)

    I can adjust my length of pull perfectly. I highly recommend this upgrade.

  7. Ben R. (verified owner)

    If your benelli has red locktite then expect to pay a gunsmith for labor or risk replacing it yourself. It will take a considerable amount of time or money. (This is not a fault to RXARMS)

    The product provided from RXARMS has 3 more positions than the LE and 5 more than the nuetured recoil rod. Fitment is great except there’s a bit of play in relation of the stock to the recoil rod. This has not been a problem so far. Overall I’d recommend this product for anyone with a nuetured benelli m4. If there’s red locktite, I’d recommend paying a gunsmith.

    • Robb Hutzal (store manager)

      Thanks Ben. In my testing I’ve not found any discernible difference in “play” in the buttstock when compared to OEM (I’m assuming you are referring to side to side play when locked into a notch). With this said, each tube and buttstock will be slightly different in tolerances which could effect this feature. I appreciate your review!

  9. Anthony (verified owner)

    The shipping was fast and the item was packaged very nicley. The recoil tube is very high quality. The witness marks are easy to read once installed onto the M4. Its also at a very competitive price compared to a factory Benelli part or third party manufacture. I highly recommend purchasing this recoil tube from RXArms. I personally had a Gunsmith attach it to my Benelli M4.

  10. Marco (verified owner)

    This 6 position tube is amazing! Great craftsmanship and everything worked and fit just like OEM! I’m finally able to collapse my neutered stock and couldn’t be anymore happy. I highly recommend this product! Before and after photos

  11. Marc (verified owner)

    Awesome fab work and the install instructions really helped. Probably the hardest part was heating up the oem tube. The lock nut did not take as long to loosen. I was using a heat gun, pretty much set to max. Doing a ‘dry fit’ and using some measurements and markings, helped get the new tube situated so that the stock fully collapsed and was properly aligned once you got the thread locker on there. Good job!

    5 out of 5. The only thing that could make this product better, is if it was titanium. Used this to put a Panzer Arms M4 stock on my Benelli Supernova!

    I found the coil tube and installation pdf were easy retro fit my M4. Great purchase.

  24. William S. (verified owner)

    Fit and finish excellent as usual. Awesome kit. Finally got around to installing this. The referenced instructions had me a bit nervous, but it was quite a painless and despite recommending some rather long heating times for loctite removal, this was completed in about an hour. End result was excellent. Thanks again Rob, you never disappoint.

  25. Jacob B. (verified owner)

    Best there isat an unbeatable price! I bought a blemished version and for the life of me couldn’t find a blemish. Rock solid lockup. Love the amount of options to find your sweet spot for length of pull. Adjust easily to fit different uses and shooters. Quick and reliable shipping. Definitely recommend for anyone looking to upgrade their neutered collapsible stock.

    Better than the factory 3 position tube at a great price.

  30. Richard (verified owner)

    Works great! Looks good too!

  31. Vincent Y. (verified owner)

    The 6 position tube is well made, and does exactly what it is supposed to do. Also, the addition of markings on the tube make it easy to know exactly which setting you are on. Also, the online instructions for removal of the OEM tube and installation of the new tube were great, although I used a MAP torch to heat the Locktite. The heat-gun wasn’t getting the job done. Overall great product.

  32. Chris (verified owner)

    Very well made, great installation instructions that are very detailed and informative. A terrific upgrade.

  33. Paul W. (verified owner)

    First purchase from RXArms, and I am very impressed with this 6pos recoil tube. Excellent quality, adjustability, and overall function. Significantly better than factory, and priced 40% below the competition! Top notch shipping and handling with tracking email notifications. My Benelli M4 with c-stock now easily adjusts to the perfect LOP! Ti bolt handle, Ti mag cap, and cheek riser are on my list.

  34. Anonymous (verified owner)

    Even though my purchase was a blem, it was still really clean and well machined. Assembly was easy and straightforward, and having six positions instead of just three is so much better for situational changes

  35. Michael W. (verified owner)

    I bought the blemished m4 recoil tube since it doesnt matter unless you gun is a wall hanger. For the life of me I don’t know why these are sold as blemishes. It looks and works great!

  36. Anonymous (verified owner)

    As ordered

  37. John (verified owner)

    Couldn’t be happier. Online instructions were spot on. Fit and finish for being a “blemished” part was phenomenal in my honest opinion. Shipping was quick, considering crossing borders. Very happy and highly recommended.

    Image #1 from John
  38. Aaron (verified owner)

    Amazing quality, was shipped immediately, directions were clear and concise. The notches are perfect and adds a wonderful multi position stock for perfect length of pull.

    All m4s need this

  39. William (verified owner)

    The Tubes finish is slightly different from factory in “color”. But it’s not an OEM tube, it’s not going to be perfect. Outside of that, you can’t tell it’s not a genuine Benelli part once mounted unless it’s side by side with an original tube.

    The 6 positions are also perfect for people with multiple LOPs like spouses, kids, etc. And it still collapses fully as well for ease of storage/carry.

    Shipping was also uncannily fast, even ordering from the US and having to go through customs I had it within 2 weeks.

    100% recommend

  40. Anonymous (verified owner)

    Excellent fit

  41. Ron LaFaver (verified owner)

    An excellent product. I had bought a blemished tube, but was surprised by how well it appeared. I would have been just as happy if it would have been considered as a perfect tube. Your standards are very high ! I can not wait for more items to become available for the M4 and am also interested in Tavor accesories. This will not be the last purchase from

  42. Eric (verified owner)

    Great upgrade! 6 position gives a more customizable length of pull over the stock 3 position.

  43. Bret S. (verified owner)

    Excellent product and well-made. Finish looks completely OEM Benelli. Both OEM part and RX part have a certain amount of slop or play… Possibly a little more with the RX Arms, but for the benefit of more adjustments, it is well worth that slight difference.

  51. Daniel (verified owner)

    Well worth the 5 stars. I purchased a blem tube but it was still a nice looking part. As a former machinist, I can see the blem but honestly most people wouldn’t notice unless you show them. Shipping was quick to the states too. Unfortunately, I can’t use the tube with the aftermarket adjustable stock I purchased. The stock (made by Panzer) requires more threads than the OEM stock to install the grip but this is my fault for not doing more research. I’ll just have to wait until i find an OEM stock and hope it doesn’t cost a fortune.

  52. Brock (verified owner)

    Well made product that has proper instructions for installation.

    I am astounded by the quality and precision of this part. The innovation and technical advancement of the tube far exceeds those of Benelli. When one finds a maker with this traits, it’s advantageous to support them.

  59. Jae S. (verified owner)

    RX Arms was incredibly helpful in helping me realize the non OEM furniture I had was preventing install, I was able to source an OEM pistol grip and am now very pleased with the recoil tube, the position indicators are great and provide much needed functionality that the original lacked. Thanks RX Arms!

    Pretty nice tube, I will say that you better have patience and a good heat source to install this bad boy. Overall I can say the length of pull is crucial to a pistol grip shotgun. Rob did an excellent job on this one. Thanks

    • Robb Hutzal (store manager)

      Hey Brent, I agree, a good heat source is crucial to make this an easier job. I recommend a heat source of at least 500f.

  78. Wally (verified owner)

    Received my 6 position recoil tube in about 6 days from Canada, excellent shipping! I will say the craftsmanship on the part is way above and beyond. Each position is numbered and the tube actually says OFF to tell you exactly were to position the stock for removal, that means no more guessing and fiddling around to get the stock off, how cool is that! I cannot say enough about RX Arms, fabulous company!

  79. Bayne Balaski (verified owner)

    As for the product, its perfect. No issues with fitment, & the quality is impeccable. Having 6 positions available really does feel like a massive upgrade to the platform.

    Excellent work, communication, & shipping Rob. You outdone yourself!
