I recently discovered that the suppressor mount for my yhm suppressor is preventing the piston removal from the front of the weapon, see pic.
I can remove the barrel (LMT MRP) from the upper and get to the piston setup that way, but I just feel that there could/should be a solution out there that I am not aware of.
Thoughts? Yes I own a grinder and dremel, but there is too much to machine off.
Ditch the piston. Switch to the maintenance free and MORE reliable direct gas impingement system.
(maintenance free other than normal weapon lube/cleaning)
Not an option…went to piston to use in suppressed role.
I knew this might be THE option though
Try a different suppressor mount.
Yup, do you happen to know of any?
I need to stay with the suppressor brand, YHM, and plan on checking with them too.
What model suppressor do you have?
Ahhh, good question…phantom LT .30 aka LT-2548
Yeah that excess material is used to stop the suppressor. A long term solution is a longer barrel (more clearance length wise).
You can run DI suppressed, that’s probably your best long solution. You can buy adjustable DI gas blocks of you really want to adjust the gas block.
Yeah
Ditching a 16.1 and 10.5 DI barrels for the 12 " piston
I would look at cutting away a portion of the top of that ring for clearance. Or take the mount and a six pack to a buddy with a lathe
Yes sir, hence my dremel comments
I’ll see what Yankee hill has to say
The top part of the ring def
Plays a role in supporting the can though.
Six pack before or after the lathe job?
Lol
I wouldn’t modify the mount at all. If you can just remove the barrel and get it that way why not just do that? If you have to have a piston deal with what you need to do to clean it.
And this was my first thought…
I did go to piston for this reason. I just imagine that this setup is possible without hindering the design of the rifle.
It’s not like the piston is going to need lots of maintenance in the first place, as long as it can be adjusted and cleaned from the back I see no issue.
I hear you. Haven’t even sighted it in yet…waiting for a good day.
Moved to the correct everyone. Thanks to all the members who didn’t report it.
This. I have the same mount (sort of… PWS FSC556 YHM QD… same base diameter) on my LMT 12" upper for years now and haven’t once needed to remove the piston for any reason. This is a non issue. Just go shoot the damn thing and stop making mountains out of mole hills.
We don’t have mountains out here!
Lol
Glad to hear that LMT is getting it done out west. I know, I know…just shoot it. I was being a little picky I guess.
Thanks for the good news Commander.
If you feel the need to clean your piston, then remove the FH/QD mount? It takes 20 seconds. Both would be done in a home type setting anyway wouldn’t they?
That was my thought. If it was installed per YHM specs, there’s not even any Rocksett/Loctite/etc to fool with. And since it’s a FH instead of a brake, no timing issues to deal with.
