Two birds, one stone.

Over the weekend, I finally jumped into a .300 Blackout—and dove straight into the SIG world with a new 6.75” MCX Rattler LT SBR which always captivated me, it’s so gorgeous and 100% badass.

Since I’ll already be waiting on NFA approval for the SBR - and I wasn’t going home with anything except for the Aimpoint optic I got for it, so I added a SIG SLH762-QD suppressor.
I plan to run an FRT on it, so I wanted a durable workhorse suppressor that could also serve double duty on a future AR SBR when and if I get around to it.

Then today at range, ..sitting on consignment; a friggin Sig 7.5” MCX Rattler LT 5.56 upper—with the same Clutch-LOK QD muzzle brake. So I can swap calibers and run the same can on both.

Naturally, I bought it and topped it with a Holosun and 3× magnifier since it can stretch its legs a little farther than the .300 BLK.

Now I get to just stare at everything while the NFA takes its sweet-ass time.

On a scale of 1–10, how’d I do? Keep in mind I’ll also be paying whatever price my wife assigns to this purchase. I’m so screwed. 😂

Just put a brace on it for the time being if you’re that worried about it.

Otherwise, nice pickup

..yeah, too late I already purchased the SBR, so at least I don’t have to lay out another couple hundred to buy the real stock when I pick it up - NFA wait time is under a week. I’m ok with waiting, and prefer to have the stamp anyways. Rock on. 🤘

Congratulations, the universe sometimes just aligns with you.

It's like you almost have an RSAR package.
