AK to M4 Stock Adapter


The Rifle Dynamics AK to M-4 Stock Adapter (Gen II) allows for the replacement of any standard fixed stock AKM (see exceptions below) to work with an AR buffer tube assembly. The angle of our adapter is designed specifically to position the buffer tube, allowing the shooter to easily access proper sight picture with iron sights and/or optics.

This feature also allows many different sling-mounting options for the individual users. Any sling adapter that fits on the AR buffer tube should work. This adapter is easy to install without modification to your AK-47, AK-74, AKM and with no need to permanently alter the stock tang.

The Rifle Dynamics RDAK to M4 stock Adapter is designed by Rifle Dynamics and made in the USA!

Shipped in the United States Only

Buffer tube, castle nut, end plate and buttstock sold separately.

Stock Adapter will not fit:

  • Milled receiver 
  • Chinese guns (Norinco MAK 90, NHM-91, Polytech, B West) Etc.
  • Vepr rifles
  • PSL
  • Yugo
  • Any side/under folder stocked rifle, any receiver with stock tang removed.

Although not designed for it, we have been told this adapter does work with the Saiga 12ga variants.

Our stock adapter will work with both Mil Spec and Commercial buffer tubes.

Note: It is up to you or your gunsmith to properly install the AK to M-4 Stock Adapter.

    Very solid stock adapter. Used a Mil-Spec buffer tube along with a Magpul CRT adjustable stock and was very pleased with the results. Thanks Rifle Dynamics !!!

    The only stock adapter that provides a correct cheek rest. If you want to modernize your AK Rifle Dynamics M4 stock adapter and ALG trigger are the first MODS you must do.

  • Modernized AK Stock

    Posted by Jim on 5th Dec 2019

    Fit to a WASR 10, came with two countersunk screws, two machine screws, and two delrin/poly bushings/washers; had a koozie swag for Red Oktober. Precision machined adapter. GREAT tube height for cheek weld to keep your sight picture, pick a stock to fit user. RD, Jim Fuller and company do some solid stuff. Makes the AK platform fit the user better. I'd put this on other AKs so long as our 2nd Amendment rights are still intact.

    p.s. Hoping their adjustable gas block hits the streets.
