Similar to our Crosman 2240 Adjustable stock, this kit includes everything you need to turn your Benjamin Marauder Pistol (P-Rod) into a custom carbine that can quickly convert from an 11-3/8″ LOP to a 15-1/4″ LOP. Included in the kit is the buffer tube, 5/16-24 x 6″ bolt, and adjustable buttstock. The scope pictured above is not included, though it is also available on our website.

The buffer tube is 3d printed from ABS plastic by a veteran-owned business in the USA. The adjustable stock is sourced from China, but is very high quality for this price.

Select “without buttstock” if you’d like to use a different buttstock than the one we provide. The buffer tube is compatible with MILSPEC buttstocks.

To install:

  1. Remove the buttstock from the buffer tube.
  2. Apply Loctite Threadlocker Blue 242 to the bolt thread (if desired).
  3. Insert your forefinger into the buffer tube and hold the bolt head while threading the bolt into the hole in the P-Rod.
  4. Turn the bolt CW at least one full turn.
  5. Turn bolt clockwise with a 1/2″ socket until snug.
  6. Adjust the buttstock alignment to your liking.
  7. Tighten the bolt until secure (Take care not to over-tighten).
  8. Reinstall the buttstock onto the buffer tube.
  9. Enjoy!

    Got mine today and mounted it In about 5 minutes time. I put Ruger 556 stock I had extra on the adapter and it fit better than it did on the AR. Nice and solid with no wiggle. Cheek weld and scope picture were perfect with the butt extended all the way. I have a
    WestHunter 4-16 scope mounted on the P Rod and this is going to make a great combination.

    Another great product from Buck Rail. What I like most about the adapter is that it is one piece. You don’t need a separate adapter to attach to the pistol and then a buffer tube to attach to that. Put the Buck Rail adapter on and slide on your butt stock, done. It is ready to go and the fit is perfect for a scope. Unlike the factory stock that is at an odd angle and hard to use. This is another must have for your P-Rod. I have no play in my stock, I installed an original Colt stock with a lever lock and it locks down tight to the buffer tube. Everything is solid. Great job.

    Added their suppressor and this stock to my Marauder pistol. Looks and fits great at a very affordable price. Have now ordered 6 or so items from them. Very happy with their great affordable products and excellent customer service.

    Arrived fast, definitely a thought out piece! Very little wobble, for this price, what a deal….

    When the stock arrived damaged, great customer service, fast to refund the stock, charging only for the buffer tube adapter.

    Don’t hesitate, it’s works great…

    Looks great on my Prod. Price is absolutely unbeatable. This is my 1st experience with an AR stock. Unfortunately I have to say does not interest me. Just to much wobble. I also had added a 3×12-40 scope. My reason for buying a Prod was light weight. I am 71 & just been switching out my airgun collection to lite weight. So i am switching back to Crosman’s stock & adding a Hawke red dot.

    I just got mine today, and I’m happy with it. It’s nice and solid once you bolt it to the gun. There’s a little slop between the stock and the buffer tube, but I have more expensive ones on ARs that are wobbly too. I don’t think you can beat it for the price
