Official SIG Rattler owner/fan-boy/nut-hugger thread

I have an 8” MPX it’s close enough IMHO.

Same here. A lot less recoil but close enough.

Got SBR paperwork approved.

MPX versus Rattler.

Both suppressed.

Posting to both the MCX and Rattler threads - there was question at the SIG Academy Pro Shop about what works with what, they suggested I contact customer support. I just heard back:

Thank you for contacting Sig Sauer

For Clarity: The upper receiver from all MCX models, including the Rattler, are compatible with all other MCX lower receivers. (Including a Rattler lower). The barrels from the Virtus can be used on older, Legacy MCX rifles, as they include the tapered lug bolt that will need to be used. The Rattler upper will work with a standard MCX lower, but cannot accept other MCX length barrels as the upper is unique in design in regards to recoil and gas management. Rattler barrels cannot be used with other MCX models either.

Kindest,

So, with that I’ll start keeping an eye out for a complete 11.5” 5.56 upper assembly.

That's excellent information. Thanks for following up.

Now we all just need to push Sig to either release the gasblock dimensions on the MCX so we can get aftermarket barrels in other calibers or have them release other caliber uppers.

I would like a 16-18" 6mm ARC upper. That would be awesome.

But before that, we really could use a rimfire variant of the MCX/MPX line.

I want to form 1 my Rattler, but I’ll wait until I’m in my new TX home - a year or so from now. For the time being, I really would prefer something better than the spinning, wiggly SIG brace portion. Here’s an option that uses the SIG brace strut that may be workable. It’s rigid and has a setscrew to prevent spinning.

Wasn’t there some rumor of some guy who was charged with making a brace into a stock just by modifying it a little (like a strip of rubber). I might be nervous at using a brace that didn’t have specific ATF approval (for now) like the SB or Sig….

The guy added the rubber tip from a cane to the back of a brace.

The case occurred in Ohio. The guy was a prohibited person found in possession of the brace pistol pursuant to a domestic violence incident. They attempted to tack on an SBR charge but it wound up being dropped.

In that instance the charge was based on the cane tip lengthening the LOP. The item from Smith manufacturing does not add any length

That is the only brace prosecution that is ever made it to federal court.

There are rumblings ATF may try to impose new brace regulations in June but for now there’s no issue.

They're coming.

Looks like August to me.

But @joshs says we don’t know exactly what it will say, yet…

… which is part of why I want to Form 1 mine. I’m curious what kind of stamp fee amnesty might be offered. (A boy can hope.)
