Getting my AAC TiRant on my Lage Upper

[WarPig]

So I got my MAC 10 Lage Upper in the mail today (of course that does me no good because I'm still waiting on the good people at the ATF to finish my transfer) but it reminded me that I still haven't come up with a solution for my silencer issue.

 

I got my Lage with a 5/8 x 24 pitch and I have an AAC TiRant with a .578x28 pitch. AAC does not, and will never, make a 5/8x24 pitch piston. I have seen a few aftermarkets and I know it will void my warranty but I don't havem uch ofa n option here (whats the point of a 45SMG that shoots 750 rounds a minute if its loud?!?)

 

So, here is one of the ones I was looking at. http://www.quietriotfirearms.com/product_p/tr45fba.htm  Has anyone had any experience with any of these aftermarket pistons in an AAC shooting full auto? I know a lot of dudes do them like this to shoot 300BO but my concern is the speed, heat, and vibration.

 

Thanks in advance!

What the hell buy it.... LoL

I know but Im hoping that can will take a little bite off the excessive rise off the MAC in 45. My buddy has one with the old school can and it helps. Given that can is much heavier.

Mark McWillis with TROS USA makes custom adapters. http://www.trosusa.com
Maybe you could rocksett an adapter to your barrel?
He does excellent work that may or may not involve a five month wait like my tri-lug 9mm barrel required.
Just thinking out loud...

Well im waiting on a double transfer so wait time is not a huge deal. The thought crossed my mind to rocksett a piston on there. Would help not to worry about the can getting loose and getting off cant and having a baffle strike or worse. But it would be a brutal break when the can wasnt on.

Actually the rocksett wouldnt work now that im thinking it outloud. Wouldnt be able to get the end cap off from the can. It would stay stuck between the piston and the gun.

Any MAC any thread pitch you're going to have to check for walk off... it's not bad .. shoot a mag or two, check the can.. some stick, some don't .. it's not hard to do and you'd be suprise given the weight how many times you're going to hold the can to balance (when you first start) ... Bowers and others make a cover you can slide over the can and then use it almost like a forearm.  I don't prefer the asthetics of them but function wise they work great and will keep you from burning yourself.

 

The walk off is just b/c the full auto, short frame .. .it's hell on anything ....you don't see this as much on pistols but if you had a F/A pistol you'd have to check that too .. the only downside to the threaded MAC barrels is you usually do not have enough of a shoulder to get a good lock up from the can .. so that's why it wanders but that's why pistol cans will often walk too .. when there is no shoulder the materials get hot and can loosen.

 

Me, I'd be comfortable getting either adapter, I'd expect both to be professionally machined, especially Mark's stuff but I'm sure QRF is plenty adequate and would perform just as well.

Gonna bump this one time just to see if anyone else has a solution to my piston issue. Thanks.
