GM Fluted Barrel Question

1063 Views 15 Replies 7 Participants Last post by  InfamousJ
Will a GM 20" SS Fluted Barrel need fitting to a factory DSP stock or is it a "drop-in" piece?

If it requires fitting, any suggestions or tips will be appreciated since it's going into a really pretty stock that I'd rather not mess up!

Thanks,

GM 20" Barrel

My first replacement barrel was the GM 20" fluted SS, good choice bro ..

Mine was a real tight fit into the 10/22 receiver. But after a few bad words and just a bit of light sanding the barrel fit perfectly. I have a bunch of 10/22 ultimates built up now, but this receiver with the GM 20" is still the best shooter of all and my go to Benchrest gun.

Good Luck,

T&R

Thanks, T&R! It actually fit right into my receiver. As soon as I get it back from my refinisher I'll see how it shoots!

I'm still wondering how much fitting I'll have to do to get this into my DSP stock.

Has anyone here got experience fitting this into a standard Ruger stock?

Thanks!

Thanks for the vote of confidence, AZGUY!

However, it's not a bull barrel, but a GM fluted tapered barrel.

I thought it was a drop-in fit, but it looks as if it will need some sanding.

I was hoping to hear from someone who had done it as to any tips or tricks that might be useful.

Either way, I will be going very slowly. This is going into a DSP with some really good grain!

That a way to go buddy. DIY and you'll have a blast doing it and the satisfaction when it is done of having done it yourself. Shouldn't take all that much work. Just rememebr that the wood is a heck of alot easier to remove than it is to put it back, lol. Good luck and we will need pics.

I did that exact job; first find the balance point of your GM barreled action, then mark the balance point inside the groove in your stock. Next, wrap your original carbine barrel in blue painters masking tape. Then wrap 80 grit sandpaper around the barrel and use it as a sanding block, starting from the balance point and working forward. Open it some, check fit, repeat. Then go to 120 grit, and finish with 200 or finer. Take out just enough for a press fit, or you can do the job with the rest of the barrel floating beyond the balance point. Stain the groove; Birchwood Casey walnut stain is a good match, then seal with 3-4 coats of Tru Oil.

Good idea of using on old barrel as a pattern. A tapered barrel is much harder to fit than a straight bull barrel. Does the original carbine barrel have the right taper?

Yes, the taper VERY is close... A GM barrel will press fit into a carbine stock with minimal sanding. The carbine barrel tapers to .5" at the tip, while a GM tapers to .60". Because the GM is wider, the thickness of the masking tape plus one layer of sandpaper creates a sanding block that removes the right amount of wood with little effort, although u have more work to do if you plan to free float...

Gents,

Thanks to your encouragement and tips I now have a barreled action that fits in my DSP stock! :bthumb:

The only thing keeping me from testing it is that I haven't put together a trigger assembly as yet... :(

I may start this evening but I'll go slow since I'd like another 2# trigger for this beauty.

Thanks again, all!!
