I really don’t want to get too far in the weeds with this, but, as I see it, it could be reasonably argued that there is a utility in having an accurate suppressed carbine of some kind for low-signature shooting at ranges not much past 100 yards. And while a suppressed .22 in a quality bolt gun with a good suppressor on the end is a fine, fine instrument…sometimes you need a bit more bullet mass.

So, how would you do that, exactly? A suppressed bolt action rifle would be pretty much ideal…no noise of the action cycling, no special mods to the rifle to allow cycling with subsonic ammo, etc. (A single shot carbine would give the same benefit but follow up shots would be rather slow…on the other hand, this sort of arm is seldom called on for volume-of-fire applications.)

So…a suppressed bolt action out to about 100 yards. One hundred yards isnt a very challenging distance with a scoped carbine, so almost any caliber will do if it can be kept subsonic with relative ease. The first thing that springs to mind is a 9mm or .45 ACP gun. Pistol ammo is easy to load down to subsonic, and .45 AARP is natively subsonic. Problem is, when was the last time you saw a bolt action 9mm of any worth? (Sure, 9mm Destroyer carbines are out there…but those are novelty Spanish guns. Repros of the DeLisle are out there, but I wouldnt call them precision.) My first thought, and still on my radar, is a Ruger 77/357….a bolt-action .357 Mag that would let me use my 9mm suppressors. Loaded with 200 gr. bullets it should be just fine for the relatively short range while providing a good platform with potential for accuracy….bolt action, integral scope mounts, aftermarket trigger availability, etc. Problem is finding one.

So, I did a bit of research and decided that while I am still going to keep an eye open for the threaded 77/357, I was going to pick up a bolt gun in .300 Blackout. This would let me use my .30 suppressor and the exterior ballistics would be an improvement over a pistol bullet. As a bonus, the Ruger version uses AR15 mags for most applications. (Depending on how you load the cartridge, an average Pmag will work fine, but if youre going to seat bullets out a bit further you might want a dedicated purpose-built .300 Blackout AR mag.)

And thus we got this:

Its a Ruger American® Rifle Generation II Ranch in .300 Blackout. I then changed out the stock for a Magpul stock. I threw the Sig SRD762-QD suppressor on there and fired a few rounds just to see how quiet it is. Gotta say, it isn’t “Hollywood quiet” but it isn’t too far away from it. I need to throw a scope on and I’m thinking that since it’s for fairly short ranges, either a variable 1-6x or a fixed 6x would be the way to go. Why the Magpul stock? A couple reasons..first, and I’m not ashamed to say it, it looks cooler. I like the sling attachment options, the subdued color, MLOK points to attach accessories, adjustable cheekpiece and spacers, and the AK-style mag release.

The only drawback to all this, naturally, is that I now have to work the logistics of a new cartridge. I’m not happy about that, and thats one of the reasons I’m still holding out for the Ruger 77/357. But I must say that the .300 Blackout was certainly ear-safe and deceptively quiet at the outdoor range. I need to go with a friend and have them shoot it as I pace off some distances away from them to see at what distance it becomes virtually inaudible.

A good question might be why not use subsonic .308 ammo? Well, I gave that a lot of thought. There’s a lot of merit to using .308 from a logistics point of view, but my experience with large (comparatively) cases with light loads has been that you get erratic performance. Enough inconsistent performance to make a difference at 100 yards? Maybe. But there was also the concern of mixing up subsonic .308 with regular .308. I don’t mind mixing up subsonic 9mm with regular 9mm (or .45) because my pistols will digest either one just fine. But my PTR-91’s may have other ideas about subsonic ammo. I may revisit this and try some subsonic .308 but it seemed that if there were going to be tradeoffs that had to be made, then I might as well do the ones that get me something more in line with what I think my needs were.

So…theres the weekend.
