How to Install a P50 Rifle Kit

How to turn your P50 into an R50.



In this episode of "How-Tos with KelTec," we'll walk you through the step-by-step process of installing your P50 Rifle Kit onto your P50 pistol. But before we dive into the installation process, let's take a moment to go over a crucial warning that comes with every P50 Rifle Kit.

Warning: Know the Laws and Regulations

A warning card accompanies every P50 Rifle Kit, and it's essential to understand its implications. The use of this kit, as well as all KelTec CNC Industries Inc products, is subject to federal, state, and local laws and regulations. It is the purchaser's responsibility to ensure compliance with these laws and regulations before acquiring the kit.

Adding the P50 Rifle Kit to your P50 pistol will make your firearm subject to ATF (Bureau of Alcohol, Tobacco, Firearms, and Explosives) regulation. It is your obligation to follow all appropriate procedures and register your firearm with the ATF before installing and using the P50 Rifle Kit.

Now that we've emphasized the importance of complying with the law, let's move on to the installation process.

Required Tools and Materials:

Included with your P50 rifle kit are the following tools and materials:

  • A small tube of blue Loctite
  • 3mm Allen keys
  • T25 Torx wrenches
  • The specific type of Torx wrench you need depends on whether you have an earlier or later model of the P50. However, you will require two Allen keys, as the spacer in your kit has screws on both ends.

Installation Steps:

  1. Begin by ensuring your firearm is clear. Remove the magazine and check that there is no ammunition in the chamber.
  2. Using the 3mm Allen keys, unscrew the two screws at the front of the gun.Hold one side while unscrewing the other, and if necessary, unscrew one side first and then the other.
  3. The magazine guide at the front also has an Allen key that needs to be removed using the same 3mm key.
  4. After disassembling these parts, ensure the spacers are in place. Use the Allen key to line up the holes and make sure the magazine guide is properly aligned.
  5. Add fresh Loctite to the screws. Typically, you should clean off the old Loctite, but for demonstration purposes, fresh Loctite will suffice.
  6. Start screwing in one side of the spacer and flip the gun to secure the other side. Simultaneously turn both Allen keys to lock down the P50 rifle kit securely.
  7. To finish, do another quarter-turn on the screw that holds the magazine guide (if applicable).
  8. After the installation, perform a function check. The P50 rifle kit should provide some resistance when manipulating it, but it shouldn't be so loose that the top of the gun flops around.

That's it! You've successfully installed your P50 Rifle Kit onto your P50 pistol. If you have any questions or need further assistance, don't hesitate to contact KelTec Weapons through their website,, or by giving them a call.
