COOL FACTORY THREADED 10-22

I’m always trying to save money if possible. While waiting for my ATF .22 cal. can stamp I’ve been looking around for an inexpensive but sexy .22 rifle for the future can. Yesterday I found it.

It’s a Ruger 10-22 that comes from the factyory with a full TAPCO stock set-up including M4 style 6 place stock, picitinny forearm rails at 12 and 6 o’clock, weaver scope mount, pistol grip, 25 round mag, and a 1/2 x 28 pre-threaded barrel with what looks like a Ruger AR flash hider installed. The Ruger box says the rifle is model #01283 and the rifle weighs <5 pounds…

I installed an Aimpoint and a Grip-pod and took it to the range today. Shooting off the Grip-pod it grouped 15 rounds into a nickel size group @ 25y. In total my wife and I fired about 200 rounds out of 5 different mags with zero malfunctions.

Price was $290 for a 100% reliable, good looking, can-ready .22 rifle that handles and looks a lot like an AR.

How long are the threads?

3

The dealer says it will fit.

4

It might have threads sized for the AR flash hider, that will be too long for most 22LR silencers.

5

If the threads were too long & it was an issue how hard would a spacer or several washers be to put between the 2?

6

I picked up one these but with the factory stock from Houston Armory a little while back, and while I don’t know the thread pattern, they did let me demo a Silencerco Sparrow and it did screw on directly.

Cansa will fit correctly on the 10/22 threaded barrel.

Double check to make sure, don’t just go by what your dealer says. 1/2x28 threads is only half of the equation, the thread length is where people get screwed up.

Saw one dude screw his .22 can onto an AR with a conversion kit. He screwed it all the way to the shoulder. Can sounded terrible as the muzzle was way too close to the blast baffle, and he damn near welded the can on the gun the threads were so screwed up, covered in carbon.

There are a couple places that sell precision ground spacers to bring AR thread length to .22 thread length. It will shorten the .635 inch thread length to ~.400 inch.

Mic the thread length and go from there.

Your NFA dealer doesn’t know what he is talking about.

You need to make sure the muzzle doesn’t touch the first baffle of the silencer. This will happen if the threads on the 10/22 are too long.

Your silencer will sound like shit and it will fuse the silencer to the end of the barrel if you do not figure this out beforehand.

You have to be careful with thread lengths, as ScottRyan said.

For my AAC Pilot the thread length was 0.438", if it was 0.635" like ARs thats almost 1/4" closer to the baffle than what it should be.

Lets hope the threads are concentric to the bore as well.
