Okay, so I’ve been playing with my 10/22 SBR for the last year or so, and rather than spending an extra $200 every time I wanted to try something new (and waiting the months for it to come through) so instead I’ve just keep changing the configuration of the one registered receiver.
That’s one of the joys of the 10/22; it’s nearly infinite changeability with nothing more than simple hand tools. want a new stock? buy what you want and 1 or 2 screws and bolts later, all done. Want a new barrel? buy the replacement and change a few turn a few screws. It’s all that simple.
Well, even before filing my form 1 for the SBR, I was aware of the scottwerx 10/22 conversion package. I recently succumbed to temptation and ordered the ‘chicago’ kit. It arrived a few days later, and with no serious issues, I installed it on the 10/22 SBR receiver. The extra front sight I ordered didn’t fit, but it wasn’t designed for this barrel. I’ll whip out some drill bits and reamers and fix that problem. (not scottwerx’s fault)
Now all that’s left is the minor work to make the front sight fit, and deciding if I want to refinish my receiver and barrel black, or refinish the scottwerx kit in silver to match the receiver.
After spending a lot of time working to make sure that the 3.5″ barreled version of my SBR was working properly, I decided to mess around and play with the configuration of it. I bought a Tactical Inc Barrel. It’s 8″ long and finned for heat dissipation. (and looks) and threaded for a suppressor.
Along with a chopped down Ramline all polymer folding stock (cut to clear the 3.5″ barrel incidentally) A custom added fore grip rail and QR VFG.
I’m using the Kidd trigger assembly in a different build right now, so I went to a Poly factory TG and did a trigger job. Using the Tac-Sol mag release means mag changes are fast and painless. The Kidd charging handle and guide rod have been retained, and I’m using a custom recoil spring. The Docter Optic Red-dot is the same One I’ve been using on the build from the start.
Running CCI SV ammo, it’s very quiet. And in spite of the 8″ barrel length, much of the bulk pack ammo I’ve tried has stayed subsonic for the suppressor as well.
All in all, it’s a lot of fun!
After getting my Form 1 back to build this Ruger 10/22 SBR, I didn’t waste much time. I engraved the receiver myself using an old set of gravers. It’s ugly, but readable and conforms to required spec’s.
The barrel is 3.5″ to keep even hot bulk pack ammo and CCI mini-mags subsonic, the sight is a ‘Docter’ optic micro red dot, the stock is a custom built bumpfire stock and the trigger assembly is a Kidd 2-stage unit.
I’ve made some of the last changes to the configuration, and wanted to answer a few questions. First off, I’ve added a Vertical fore-grip and extended the thumb stud. This is what the updated rifle looks like:
And I wanted to explain some of the modifications to the stock.
When I added the choate folding portion to the stock, I machined away the fixed stock to fit the folding mechanism and butt-stock section. I also cut down the front end of the stock. Here’s a comparison next to a standard AA stock:
As you can see the choate folding portion is a good fit, and allows the overall length to be much shorter.
The LMA mechanism is what allows the magic to happen, it’s a series of linear bearings and precision ground rods intended to reduce friction. The photos below show the LMA in the rearward and forward position. The block that is moved in the photos actually remains stationary in the stock, and allows the guns action to smoothly slide forward and back.
I hope that helps to answer some questions!
