Compliant Models & Features

PTR recognizes that not all state laws are the same.  When considering which PTR model to purchase, careful interpretation of state law is crucial.  With that said, PTR offers a full line of rifles that help meet the criteria certain states require.  PTR can meet the needs of almost every customer, offering models that have a welded barrel extension, fixed or pinned stock, and low capacity magazines.

 

If there are restrictions that have not been addressed above, please contact sales support at PTR and a solution will be found if at all possible.  PTR's friendly and knowledgeable staff will be happy to help explain how to properly obtain and legally possess our firearms in your state.

Sights

PTR uses the world famous H&K style hooded front sight and adjustable rear sight drum

Rear Sight
  • The rear sight is adjustable for both windage and elevation. The owner’s manual has step by step directions on how to make adjustments.
  • Though not necessary to adjust elveation, an H&K sight adjustment tool may prove helpful
Front Sight
  • Front sight is hooded and set in a triple tree frame
  • Front sight is fixed in place
Magazines

PTR recognizes that keeping shooting costs low is a target for all customers. With that in mind PTR uses original G3 aluminum magazines in its 91 series of products. And, in an effort to further our customer’s savings, PTR adapted the 32 series of products to work with most standard AK-47 magazines. In short, all of our products will accept inexpensive magazines that are abundant in today’s market.

PTR-91 Series Products
  • 20, 10, and 5 round G3 magazines are available in Steel or Alloy
PTR-32 Series Products
  • PTR ships each 32 series product with a polymer AK-47 magazine.
  • PTR recommends the use of Magpul AK-47 magazines for best results.
  • GEN 2 PTR 32 series products are designed to function with the majority of available AK-47 magazines.  PTR recommends the use of Magpul AK-47 PMAGs due to their optimal function, wide availability, and value.  PTR will warranty the efficient function of commercially available, new production AK-47 polymer magazines in the GEN 2 PTR 32 series products.  Many types of steel or aluminum military surplus magazines will function in the GEN 2 PTR 32 series products, however due to the wide variety of manufacturing tolerances in use, PTR cannot warranty the functionality of military surplus AK-47 magazines in the GEN 2  PTR 32 series platform.
  • Due to the variations in AK magazines made by different countries, you may find that not all AK-47 magazines will work.  PTR typically finds that 7 out of 10 random magazines work, and that the customer may need to mark the magazines that specifically work with the PTR 32 series.  The PTR 32 series will not work with bolt hold open magazines.  The 32 series will work with Pro Mag AK drums.  The 32 series will not work with metal AK drums.

If you have any further questions regarding such topics please seek assistance from your local ATF office or state police.

Ammunition

PTR sells products chambered for multiple calibers.  Nomenclature of cartridges can be confusing.  It is vital that you understand cartridge nomenclatureand only fire cartridges for which your purchased firearm was designed.  To assist you, the name of the appropriate cartridge will be stamped on the receiver.  If you have any questions regarding the appropriate caliber cartridge for your product please contact PTR prior to firing!

 

Please remember, PTR recommends the use of original, high quality commercially manufactured ammunition in good condition.  PTR will not honor claims which may result from careless or improper handling, unauthorized adjustments, unauthorized parts replacement, corrosion, neglect, or the use of the wrong type or caliber of ammunition.

 

Due to the nature of the delayed blowback roller-lock system - specifically the extraction process and its resulting damage to the casing; PTR does not suggest, recommend, or support the reloading of any cartridge fired from a PTR product.

 

NOTE:  Some types/brands of ammunition have unique characteristics that reduce liability in semi-automatic firearms.  PTR strongly recommends that you purchase and test a small quantity of any type of ammunition in your firearm prior to purchasing any particular item in large quantities.
