Last year’s virtual SHOT Show revealed the space age P50 from KelTec. If you’re not familiar with the P50, then you’re missing out. Well, you’re missing out if you like weird guns.
The P50 is this crazy, retro-futuristic 5.7x28mm pistol that uses P90 magazines. It’s a handgun, but a really, really big one.
Big handguns can be tough to wield. Short rifles are much easier. Thus, KelTec has released the P50 rifle conversion kit.
Make It Bigger
Now P50 users can convert their really big handgun into a rather small carbine. The drop-in stock and barrel allow you to better control the firearm and add a little range to the thing without much difficulty.
The barrel is 16 inches long, so there are no NFA worries. However, if you’re a stamp collector, it’s not exactly hard to SBR the gun either.

The wire-type stock of the P50 rifle conversion attaches to the pistol grip. It’s fairly simple and effective.
KelTec wisely made it a folding stock to help keep the size of your subgun down. The stock is essentially a metal pipe with some curves and a polymer butt plate. Nothing fancy, but it’s effective.

The barrel of the P50 rifle conversion is threaded and, well, it’s 16 inches. However, it still looks rather short. The P50 already has a 9.6-inch barrel. That big long barrel doesn’t look absurd like a lot of 16-inch barrel MP5s or similar firearms.

I asked the nice people at the KelTec booth about a brace, but that doesn’t seem to be on the menu. That being said, someone will surely come along soon and make one. KelTec firearms seem to be a favorite of the creative types.
Look for the rifle conversion kit later this year and plan to spend around $300 for it.
