Hey guys,

I'll spare you my life story, but suffice it to say that I recently sold my first rifle (Savage 110 in .30-06), and I wanted something else to replace it. As much as I'd love to build an AR, I decided I couldn't afford it right now. Plus, I really like the idea of having a rimfire rifle, and a non-restricted one as well. So, after much deliberation, I went with the 10/22.

I'd planned on building a short-barreled rifle, with a pistol grip and skeleton stock. I also wanted a stainless receiver and barrel, but I knew availability was scarce, so I got myself on a couple waitlists at the local stores and settled in for the long haul. In the meantime, I started looking around the forums and the EE to see what parts I could find. I knew this build would take a while, but I was committed to a 10/22, so I figured I could start picking up pieces as I went along. I was looking for an AR-style chassis to start off my build, but I wasn't terribly thrilled with the commonly available ones. I was looking at an NEA chassis when an RB Precision Evolution stock came up on the EE. After a few messages with the owner, I picked it up, and a few days later it was in my hands.

Now, I'd planned on using the factory iron sights to practice, but once I had the stock I realized the buttstock was going to be too high for me to do that. So, back onto the forums (and the EE) to hunt for a red dot sight. Instead, I ended up with a pair of Magpul PTS back-up sights, thinking that I'd save up some cash and get an Aimpoint later. However, I wanted to mount both sights to one rail, and I didn't think the top rail on the stock would be long enough. Plus, I really wanted to mount a rail to the receiver (so I wouldn't have to worry about re-zeroing sights after every cleaning), so off I went to visit Joe Dlask and picked up a 12" picatinny rail blank.

Once I had that, I had to wait until I got a rifle before I could start assembling everything, but I could see how it was going to turn out. I put up a wanted ad in the EE, and had a bit of interest. In the meantime, I kept scouring the EE for other parts, and stumbled across a Bushnell Zoom Dot. It looked pretty good for my needs, and the price was right, so I let a bit more money leave my bank account.

In the meantime, I'd had a guy message me and offer me a clean SS 10/22 carbine for a great price... He'd had it for about four years, but had barely shot it. It even had the trigger reworked by Dlask to lighten the pull. After a few messages back and forth, we finally settled on a time to meet. That time was yesterday, and I spent the afternoon getting acquainted with my new rifle and coming up with a wishlist of parts (which I've already posted in the EE). I also started doing some fitting to see how it would all come together. But, onto pictures...


The rifle, as it arrived, along with the RB Precision Evolution stock, bare picatinny blank, black Evo rail, Magpul MBUS, Harris bipod, and a sling:

Close up of the receiver; I think I may have gotten lucky and have one of the older rifles with the clear-coat, before they switched to the painted finish:

Here's the rifle in the new stock, with the Magpul sights mocked up on the original top rail. The silver picatinny rail above will be replacing the short rail, so I put it there to give an idea of size:

A close-up of the action in the stock:

The stock scratched the finish on my receiver, so I went over it with some 400 and some 800 grit sandpaper to clean up any rough spots. It was nicer, but the action still had a bit of lateral play (although the takedown screw wasn't fully tightened). In order to prevent future marks, and tighten up the fit, I cut some cork drawer liner to fit and lined the inside of the stock, where the action sits:

The fit is much better now, with no play at all, but it's quite difficult to get in there. Plus, I left too much of the liner in the magazine well, so I can't pull the magazine out any more. I'll probably remove this and use something thinner instead, like some sort of vinyl tape.

Overall, I'm happy with the progress. However, the barrel cover on the stock sits a fair bit higher than the receiver, making it difficult to mount the picatinny rail, so I need to pick up a section of aluminium and fabricate a new cover. I also want to take apart the trigger group to do the auto-bolt release mod, so that'll be done soon. Other than that, I'll slowly be acquiring parts for the build... I'm planning on a short barrel (10" or 12-1/2"), extended magazine release and charging handle, and some other good stuff.

As for why I'm calling it a "utility" rifle: I was reading a thread on one of the forums discussing what people considered "tactical" rifles, and someone made a good point that a lot of things (including squirrel hunting) can involve tactics. They also mentioned that not all tactical rifles are the same, and that a tactical sniper rifle will look completely different from a tactical CQ rifle. They suggested that "utility" was a better term.. Simply: 1) fitness for some purpose or worth to some end; 2) something useful or designed for use. I liked it, so it stuck.

I apologize for the long post... I've been holding back until I had the rifle in my hands. I'll be updating as I do things/acquire parts.
 
I don't seem to be getting much love here, but maybe this will help... Update time!

Ladies and gentlemen, I present to you the first (as far as I know) full-length, receiver-mounted, cantilever picatinny rail for the RB Precision Evolution stock:

I don't have any pictures of the work that went in to modifying the rail, since it took a hell of a long time and I was too busy trying to get it done. Basically, I started by cutting down a section of aluminium channel to make a barrel cover, then trimming it to sit about 1/8" lower in the stock than the original cover. Then, I placed the rail so I could get two of the screw holes directly in line with the troughs, and marked out where I needed to trim the rail to get it to clear the barrel cover. Next step was to cut the rail... Took me about half-an-hour with an angle grinder. I ended up doing it next to the outside water tap, which was nice as I had to cool the rail down every couple minutes during cutting. It would get so hot, that it would vapourize the water as soon as it contacted it.

Once that was done, I did a bit of smoothing out with a couple files, and drilled out two holes for the front and rear receiver holes. I started off with a 9/64" bit (just big enough to clear the threads on the screw), and then followed it up with a 1/4" bit (for the screw head). Finally, I used a file to give the underside a bit of a curve, so it would hug the receiver a little better.

It took me probably about 4 hours of work, but I think it works pretty well, especially since it was all done freehand (I don't have a drill press or any power sanders). I need to get some longer screws and do a bit more tweaking, but it's all nice and solid so far. And, most importantly, it sits above the barrel cover, so there should be no movement in it due to the stock, and no loss of zero while cleaning.

My original plan was to spray paint the rail and cover black, but now that I see it, I think I prefer the silver. I need to do a bit of tweaking to the barrel cover and rail though, then clean them up, give them a brushed finish, and spray on some clearcoat. I also picked up a sight off the EE recently: a Bushnell Zoom Dot. I just need a higher mount for it... It's a bit low for my liking, but I'll probably go do a range test before I swap it out.

It's a work in progress, but I'll keep updating as things happen.
 
Thanks guys, I appreciate the comments... To be honest, even I didn't really know how it was going to look when I started it, but I like how it's coming along. I'm starting to pick up on little details that I want to tweak, so it's really starting to evolve in my mind.

Case in point: The barrel cover. I like the look of the barrel cover, and I intend to keep it, but I found it had a couple major design flaws (at least in my opinion). The first was the height... It sits so high above the receiver, that even if I'd done some major trimming to the rail, I still wouldn't have enough clearance between the two parts to mount or use my sights.

Solution: Lower barrel cover (which has already been covered).

The other issue is the fact that the barrel cover attaches to the stock with five screws on either side, and because of the design you have to remove them all in order to remove the barrel cover. This wouldn't be a problem, except for the fact that these holes also act as the mounting points for the side rails... So, if you've got side rails installed, with accessories, you now need to remove those accessories, then remove both rails, before you can pull out the barrel cover. If you've got a laser, this means you need to re-zero it every time you clean the gun.

Solution: Modify the cover so it can be removed without removing any rails or the action.


Here's a picture of my modified barrel cover on top, and the original on the bottom (front of the barrel covers is to the right):

You can see the five threaded mounting holes in the original barrel cover. I haven't drilled the holes in the new cover yet, but it's been modified to use only the front two screws. The rear section has been cut away to clear the three remaining rail mounting screws. I'll attach the rails using three screws and nuts, then slide in the barrel cover from the front and install the last two screws on each side to hold it in. Now the barrel cover can be removed without pulling either of the side rails.


Here's another picture of the gun with the barrel cover removed, and you can see how the rail attaches to the receiver but floats over the rest of the barrel and stock:

Unfortunately, since I had to trim the rail freehand, the underside is not perfectly straight (I can see a bit of unevenness in the thickness). It's also slightly flexible... I can push down on the front of the rail and it bends relative to the barrel, but I figure that as long as I'm not mounting any heavy accessories near the front (just the MBUS), it shouldn't affect the aim at all. I was going to take another picture with the cover installed, but I forgot. I'll try to get the holes drilled and tapped tomorrow, so more updates when it gets done.
