  • CALIFORNIA CUSTOMERS: Verify with your receiving FFL before you place the order!!! We are seeing some FFL's accept these and others are being extremely difficult and forcing customers to ship these rifles back to us. Verify with your FFL!

We are now opening up options for you to customize how much work you want us to perform on your rifle conversion, to offer a more flexible price point for those who are looking to save and perform some of these tasks themselves!

Rifles ordered without paint/refinishing can expect minor dings and paint/finish wear from machine work. Examples: Any cut surface will be bare (magwell, bayonet lug, front sight), mag catch is fitted to a variety of mags, minor paint chips may occur, and metal shavings will likely be present.

Each Optional service adds to base price:

  • All rifles will receive the magwell cut from single stack to double stack to accept standard AK mags
  • Conversion Option: Welded Muzzle Nut Removal - Cut weld on muzzle nut to reveal threads underneath
  • Conversion Option: Bayonet Lug Cut - mill bayonet lug to accept bayonet mounting
  • Conversion Option: Touch up paint on machined areas (adds working and drying time, may add up to +1 week to process order)
  • If you are looking for the DIY package that we have always offered in the past, choose all of these options!

This is a firearm so we must ship it to an FFL holder.

During Checkout you will be prompted to type in and select your FFL. If we have them on file and place your order, no further action is needed and we will ship within 5-7 busines days or less, depending on order volume.

If we do not have the FFL on file, you will receive a notification that we will need to receive a copy of that FFL liscense. At that point, please have your FFL dealer email us a copy of their FFL to and reference your order number and name. Once we receive it, we can finish processing your order.

Our full FFL policy can be found here. Thank you!

    So close!!

    This really is a great feeling rifle. Has zero finish issues or fitment issues, and I cannot begin to express how much I like that it mixes the AKM with the 5.45 round. They completely missed the mark with the barrel, however. The nitride barrel significantly lowers my rating on this AK. 5.45 is very commonly a corrosive round, so the nitride to me was almost a deal breaker. Hopefully a good supply of CHF Chrome Lined barrels can be produced by somebody in the near future and I can swap this stock barrel out for one that will really stand the test of time. Other than that, zero complaints.
