Now that Sig has announced that they will be selling Rattler uppers, if you drop one on a standard AR lower can you still use the factory collapsible PDW style stock or brace?
View Quote
Yes, the AR/M16 lower adapters have pic rail on the rear (just like an MCX/MPX lower) for using an MPX/MCX stock or brace.

I'm asking about this stock specifically since there appears to be a channel cut out to accommodate it in the standard MCX lower:

Finally got to shoot my Rattler (hybrid)* pistol today! Only had a 25yd indoor range to work with.

Fed it Magtech 123(?)grain, Barnes 110gr, and some of the Hornady 190gr subs. POI for all of them at 25yds was the same (within my margin of error). If I wanted a 100yd zero for the 110s where should they be hitting at 25?

The subsonic would not reliably cycle. Brass would eject but no new round picked up, even on +gas. No stovepipe or FTE, just a "click." I'm 100% unsuppressed for the foreseeable future but it would be nice if it would cycle subs anyway. I was using Pmags, both the 556 and 300 design. I'm hoping once the gun loosens up (recoil springs break in?) it will be more forgiving.

Everything else ran great. LOUD!

When I got home I realized that I had forgotten to add any lube so it was running dry.

*I can't buy a whole Rattler in my state so I had to buy the Upper Kit and put it on a pistol lower I already had.

Sig could really be on to something with this but at that price you can buy a whole gun.
Wish they would price the uppers and conversation kits closer to that of an AR barrel/upper.

With that said, I'll probably still buy one if I can get a good deal. I already have a form 1'ed MCX lower.

I can't get excited about a SIG.  If I really believed they'd keep making the latest/greatest model more than 3 or 4 years I might feel differently.  I'll keep the two SIG rifles I own (both discontinued models) for as long as I can get parts to fix them (neither have broken, but most things will, sooner or later).  I just won't buy more.

That's not unreasonable.

That said, the 556 never enjoyed any real adoption during the 12 years it was in production. IIRC @Coregon posted (last year ish) the MCX had already sold more in the 2 years it was in production than the 556 did in its entire production time.

Agencies and organizations didn't want the 556 (those that did were better served with Swiss 550/551/552) but there sure seems to be a lot of interest in the MCX and they aren't competing with their own product lines.

All of this + the fact that the 55X series of guns are just so damn expensive to manufacture, especially in the US.  It just didn’t make any sense, considering MCX was being released and orders for 55X were plateauing.

I love the 55X series and glad Sans Swiss still makes them available for import.

View Quote
Unfortunately, no. The conversion block's channel indents aren't as deep as the channels in the upper; they're more aligned to fit the round part of the AR lower.

It's actually very close -- the collapsible brace, with rods extended, will fit over the conversion block and AR. But when you clamp it onto the 1913 rail of the conversion block, the rods can no longer clear the channels. Does that make sense? I'll add some close-up pictures for illustration. Note that when the rods are collapsed over the upper, the collapsible brace block is not attached to the conversion block.

I think with some very light machining to the insides of the rods, it would definitely fit. But unfortunately I don't have the tools or capability to do this. :-/









Edit to add: I haven't tried the collapsible stock, since mine is a pistol (I'm in CA, so no SBRs allowed).

ETA: Looking at your pics do you think it would work with a small picatinny riser sitting between the stock/brace assembly and the lower?

I don't think adding distance will help -- even when the rods can make it over, they catch when retracting. Some material needs to be removed from the inside of the rods to clear the conversion block and AR lower... but not much! Probably something around 1mm on each side. Maybe less.

Finally got to hold one in LGS Saturday, it had one of the new pistol grips.  I am a left handed shooter, and when I was holding this pistol grip firmly everything was fine and felt good, but when I lowered the gun to across my chest and loosened my grip, the firearms lower receiver instantly pinched my hand between my thumb and trigger finger.  I own an mpx and a friend has two MCXs and this is my first time experiencing sticking kind of pain/discomfort.  It was instant discomfort if pistol grip was not held very tight.  Maybe it is just the pistol grip, might have to try one with a different grip.

Handled one at the LGS yesterday. For as short as it is, that thing is flipping HEAVY.

For that price I can build two pistol ARs and SBR one... which is exactly what I'm doing.

Love the design, but they need to shave some weight off it and lower the price for me to give it a second look.

I agree it felt pretty heavy. And you know most have intention of running a 30 cal suppressor on the end of it so it's gonna be a dense package.  Man does it look bad though.

I honestly don't know where that weight on our website comes from.  That said, I don't think it feels heavy, even with a can on the end.  I think it balances really well suppressed or unsuppressed.

That 9” MCX barrel will get you pretty quiet with the right ammo.



It’s happening in the next couple of weeks. I’m collecting enough subsonic ammo to make the test worthwhile. Slight disadvantage since I only have the Trash Panda and the SRD762QD-Ti at the moment. To be a fair test I should have the Thunder Chicken.

Still, I’m betting that th dB difference will be +/-2 - virtually imperceptible to the human ear.

Honestly, I love them both. Each has a unique character and feel. Sig allowed me to buy the Rattler and I hope Q lets me buy the Honey Badger. (It is a rare event for me to buy a review gun.)

They share designers and DNA. It’s only appropriate that they have similarities.

I agree they are both awesome guns. I have the matching HB silencer as I got the first run. My serial number is less than 80. I just a little surprised by the difference port noise. Could be you are just closer to the Ejection port due to cheekweld on HB. I just need that Mp5sd I keep talking about to complete the goloud experience.

I do love the SD. But it doesn’t get shot as much recently. Mostly due to weight. It’s a beast fully loaded up.
