Something like the seekins or spikes bar.  Also aero precision has their m4 e1 uppers/rails and right now till Tuesday it's $235 shipped for the complete upper receiver with 9" keymod rail. You can also choose mlok and quad rail, all in various lengths. They fit 1.5" od suppressors.

They are 1.8" ID.  I have a 1.75" ID rail right now and it feels/looks huge compared to the 1 3/8" suppressor.  I really need a smaller rail.

The outer diameter of the Mystic's locking ring is 1.462.  Not 100% sure its the same on the Infiniti but i know they are similar designs.

I run my Mystic on a 5" sbr with a 9" Seekins Sar rail.  The inner diameter of that rail is 1.5.  It fits, but its a very, very tight fit.
It also sees time on my 8" 300blk under a 12" Seekins mcsr v2. I prefer the added clearance of this rail.

I really like the Sar rail for a 1.5 ID quad rail.  But I recommend you look at the larger handguards..

I'm running an Odin Works with my 1.5" OD can inside it.

Chek them out.

I have almost the same setup (Liberty Mystic). As someone mentioned the lock ring of the mystic makes the OD of the suppressor 1.46. I use a Samson Evolution 9" rail. It works fine as long as you don't want to actually mount anything. The small sections of rail won't attach to the rail with the suppressor on because there isn't any room for the screws on the inside of the rail, they hit the suppressor.

I think I've picked a rail, but I need to know how long.  I have a 5.5" bbl which sticks out of the upper 4.5".  The supp is 8" long, but I don't know how long it will be with the magical mystery 3-lug mount that I hope to get before the form 4 is approved.  I'm thinking 11" rail would leave 2.5" or so sticking out.





Thoughts?

I used a KAC 10" URX4 rail with my 5.5" TROS barrel w/3lug and my Infiniti sticks out 2.75" from the end. I like having enough to attach/detach. Good luck.

I like this.  Do you have a picture of the rest of the gun?   Where did you get your 3-lug adapter from?  Can you fit keymod attachments on and still clear the supp?





Thanks.

3 lug is part of the barrel, not an adapter, TROS for the win! My KAC keymod covers would possibly fit with some mods to the attachment area, otherwise a no go, pretty damn tight.

My barrel is 3-lug also.  You have to have some kind of adapter to connect the suppressor (which does not have an integral 3 lug attachment) to the barrel.



If nothing can be attached I'm going to have to look for something with a larger ID.  I don't want to spend all of this money and have no way to attach a light, etc.

Ahh shit, reading is fundamental. I use a Gemtech 3 lug adapter.

Whose suppressor will you be running?  I have  3 lug adapter for an Octane I can measure for you...

Did you see that they are no longer warrantying issues when using Gemtech mounts?  Per their website.



Stalking Rhino told me their adapter is 1.5".



Looks like I need a rail with a 1.6x I.D.  Any ideas there?  Rainier's site has a pretty good selection, and none of theirs fit the bill.

I've got a Wilson TRIM. ID is listed at 1.47". I have a Mystic X in jail but it'll be interesting to see if it fits. I haven't seen any pictures of this setup yet to know if it works.

Yes, and it's total BS, because they originally advertised that the Mystic/Infiniti line would be compatible with all GT MM adapters.

Troy alpha is way smaller than 1.5" inner diameter.

They need to come out with their own 3 lug adapter. I still don't know whether to go threaded or 3 lug when my Mystic gets approved.

The I.D. is 1.55" so it is similar to other rails listed in this thread...  Probably too small to connect anything to.

AM-TAC has rail sections that have a left hand thread retainer for the keymod portions. This setup end up flush inside the rail instead of sticking down into the can like a spec keymod nut would.



you might be screwed with accessories though.

All I need is rail sections.  I don't have any keymod accessories.  I'll call them to figure this out.

I think I'll try AM-TAC 9.5".  It may be a little shorter than I'd like but the next size is 13".  Per Ambush:



Michael,



Thanks for the inquiry, our KRS V2 will be perfect for you.  



Inside diameter is 1.57" just for this reason.  Our keymod accessory rails are

also the best in the industry since they use our proprietary single piece HD

locker screws instead of the old two piece screw and back system.  They will

tighten down over your suppressor without interference.



Don't forget Michael, the KRS V2 also incorporates our original QIK System for

sing attachments into the keymods and the best barrel nut lockup out there.

I hope you choose AM-TAC for your next handguard sir. Shop online or call one of

our sales associates here at the shop 208-906-0585
