Upgrade an old 18T mount using the Sakar mount?
I wonder how feasible (with the right equipment) it would be to cut off the AAC mount on a 18T can and thread the back of the can for the SilencerCo mount. Then you thread on their mount and bam, you've updated your 18T to 51T.

Gonna try it on my raider. I'll let you know how it goes.

Do it and let us see you do it.
Member of the LSU, SWR, and RUGGED underground. Shame Silencerco!
Re: Upgrade an old 18T mount using the Sakar mount?
Any luck? Do you think you guys might offer such a service? I would gladly pay to have a solid, 51T friendly mount put on my 18T can. I'll probably be buying your Sparrow here pretty soon too, its just such an awesome 22LR can and oddly enough I don't have any 22LR cans yet.Gary_SilencerCo wrote:Gonna try it on my raider.

What's wrong with your 18T mount?? I'm glad I have it over the 51T rattler.

Here's my 762SD (18T) on my M1A. Watch the piece of tape at the 12 o'clock position on the can:What's wrong with your 18T mount??
Showed the video to AAC and was told to bend the retention springs and that would help.
When that didn't help I was told to send it in to AAC for repair.
It spent 10 weeks at AAC getting the retaining springs replaced and retention was no better when I got it back.
I have a half dozen different 18T mounts (on a half dozen rifles) and the can backs of all of them.
If Silencerco ever offers a SAKER in 30 caliber with a mount interface compatible with the AAC 18T mount i will retire my 762SD and buy the SAKER.
I'm tiired of having to check alignment ever 3 rounds.

Bookhound (Formerly of Polite Society, now Accurate Ordinance) has a pretty simple fix for you:
I don't have a back off problem like you do really, but I though I'd try something similar:
Now, bookhounds fix is much more solid and they align the hole to the proper valley in the mount.
I just used a 4-40 tap and put the threads where the spring is. This pushed on the spring and keeps it from pressing up.
I used a 45 cent 4-40 set screw from the hardware store. The problem with my version is that you only have threads on two sides of the set screw rather than all the way around. It would be easier to work loose. However, my fix keeps the original spring so that you can use it on guns that don't wobble loose. I also haven't tested my "fix" yet either. The screw may work it's way out quickly, I don't know. I'll probably upsize the set screw next. The 4-40 is a little on the small side.
So, either way, if I were you, I'd at least contact accurate ordnance. It may fix all your issues.

To Silencer Co... I would pay to have my M4-1000 upgraded to a Saker mounting system.
Re: Upgrade an old 18T mount using the Sakar mount?
Wow. That sucks. Mine is the M4-1000... I've heard of 18t problems, but mine has been solid... full auto and everything.ATCDoktor wrote: I'm tiired of having to check alignment ever 3 rounds.
Re: Upgrade an old 18T mount using the Sakar mount?
Thanks Chris but I spoke to Bookhound about his remedy and it appears that their fix is "mount" specific.So, either way, if I were you, I'd at least contact accurate ordnance. It may fix all your issues.
Having six different rifles the chances of the set screw lining up with a "valley" in the mounts on every single one of them would be remote.
If I went with Bookhounds fix, on the mounts where the screw didn't line up, I'd have to back off a bit to line it up.
The vibration associated (right now) with the can backed off (from full tightness) is ruinous for accuracy.

Re: Upgrade an old 18T mount using the Sakar mount?
That's one reason I like my "mod" a little better. It doesn't replace the spring, it just keeps it locked down so the silencer can't move from the current valley.ATCDoktor wrote:Thanks Chris but I spoke to Bookhound about his remedy and it appears that their fix is "mount" specific.So, either way, if I were you, I'd at least contact accurate ordnance.

Since I'm not removing the spring, or changing the valley that it is landing in, I can choose to use the set screw or not and nothing changes if I don't use it or it doesn't work.
Re: Upgrade an old 18T mount using the Sakar mount?
It doesn't work for me because I have 51T mounts on all my rifles to fit my 51T can. I can still use my 18T can but it backs off the 51T mounts really quickly, so you have to watch it closely. Having the collar mount like the SAKAR, would make it rock solid on the 51T mounts.chrismartin wrote:That's one reason I like my "mod" a little better.

It won't be the "easy" fix some of us thought it might be. I called SilencerCo and their MSRP on the mounts is 300$. At 300$ plus another 200 or more for any labor to make the upgrade your sitting at 500$ before shipping, etc. Thats a big chunk of change for an upgrade.

I don't think your following my intent.
If Silencerco comes out with a SAKER in 30 caliber (with an 18T compatible mount) I'm shitcanning my 762SD and using the SAKER on my AAC 18T's.
Thats the easiest fix in the world (for my specific proiblem).

I can't disagree with you one bit about your problem. It seems to either be just fine (like my friends 18T 762SD that he was shooting out to 700yards without any loosening) or it seems to be terrible, like yours. I probably wouldn't dump the can, but I would consider making it a one horse machine and using the set screw method.
I also wouldn't honestly keep the 18T mounts. I'd switch to SilencerCo's mount and make that 762SD a "thread on" can (or sell it). Its why I switched to a 51T mount, which works excellent (for me. apparently some people have issues with it not being tight on the last tooth and having some tiny wobble. enough to effect accuracy).
I've pretty much decided for all my LR rifles I'm going to stick with a 2 point mount or a thread on mount. It just makes the most sense for precision rifles.
