Just thought I would give everyone a heads up about the cool new 1/2"x28 spacer that silencerco is coming out with. It isn't in the official catalog yet but should be released soon. The neat thing about it is it has an internal o-ring which gives it a really snug fit. I tried one on my threaded ruger 10/22 tactical and it fits and works great. I just got it so haven't had a chance to really run a ton of rounds thru it yet but plan on putting it thru its paces this weekend. I am in no way affiliated with the company but have become a big fan of their products. Here are a few pics so you can see what the new spacer looks like.

Is the spacer threaded?

Spacer is press on, not threaded. The internal o-ring design forms a good seal between barrel and suppressor when you thread the suppressor on. Actually a pretty slick deal.

The point of the spacer is to keep the muzzle from being installed too deep in the silencer and damaging the internal parts. I tried to buy their old one ($10 and without an o-ring/seal), but they were sold out on their web site. I went to the local industrial supply store and bought a thick washer which works fine. I don't see any gas blowing past the seal in the supressor and down the threads. Total invested.. $1.30 ( I bought 2).

FYI...Gemtech has threaded spacers but they are sold out. Not sure which is better...

If it costs more than the original, I don't see it being worth it. Not sure what you'd be trying to "seal" in this case.

I made this spacer for my Spikes upper. Center was reamed to 1/2". I don't think it can tilt as much as that one in your photo does.

I had thought about the washer idea but didn't like the way they fit or looked when I tried it. That one you made for your spikes looks good on the other hand. The non o-ring one from silencerco works fine and looks good with suppressor attached... If you are installing a supressor on one weapon and leaving it there, no biggie. My issue is I only have one suppressor and use it on multiple weapons so for me, I think the o-ring version is the way to go because the o-ring forms a nice snug seal around the barrel on my 10/22 and is less likely to get lost when I swap the suppressor over to other weapons, etc. When I compare the silencerco regular spacer side by side with the o-ring version, to me i think the o-ring version is definately worth a couple extra bucks to have the nice snug fit. YMMV.

The gemtech looks way better IMO.

Hi Guys. I've recently taken the job of Manufacturing Manger at Silencerco and this was my idea. I got tired of my spacer falling off and the threaded versions often will lock on when you tighten the suppressor, requiring a tool to take it off. This solves both problems––it stays on the barrel when you want it to, and it comes off easily by hand. BTW, It doesn't really seal anything, it's there just to keep it from coming off until you want it to. These aren't in the webstore yet, but we should have them up shortly. I originally wanted a threaded version, but realized that they're so narrow that after a proper thread relief you'd only have room for about 3 or 4 threads and I just didn't want to go there. For a simple little part, I wanted an elegant solution and I'm hoping customers like it.

Also, please be careful with washers. They are by no means precision made and the silencer relies on the squareness of the shoulder it seats against to align the bore. It's an expensive gamble to save a few bucks.

I still prefer the thread on, I buy one for each rifle and I dont take them off so requiring a tool is not a big deal. Im with the guys above the gemtech one is better I just wish it was rounded for looks but oh well. I inow gemtech made it like that so it was easy to get off but like I said I dont take them off anyway.
