The only reason to do so for me is a smaller footprint for a bag gun.  

I typically have an EXPS on a unity riser on my MCX.  If I'm using it as a bag gun where I want it as small as possible, I'll do minimalist stock and UKON with an RMR because its as small as you can get and still have a dot.

They didn't say why but the store rep there who helped me said that they had stuff in-stock in the store but were "notifying" those who had ordered them. Once a certain timeline expires on notification without a response, they put it on their shelf and refund the buyer.

Poorboys YHM riser.

I would have bought the Unity riser, but wanted something that would fit the EoTech and Magnifier.  I didn't want to use the Unity mag riser and didn't realize I could fit the Eotech and magnifier with stock mount on the Unity rail.

Regardless it works well for and affordable price.

Sig bros.  Can you guys trouble shoot something for me?  @coregan

I’m going to use an SRD338Ti-QD on an MCX.  I have the brake.  It appears that it’ll require me to use the taper adapter, as the barrel protrudes to far to seat the brake portion on the mount, which is disappointing.

Without adapter:


The problem I’m having is the brake includes a crush washer use to time the brake portion of the muzzle device.  I watched a video with the bald, goatee guy from sig.  He seems to gently insert the crush washer into the recess of the muzzle device.  Not sure if the crush washer included with the device is too big.  Am I suppose to deform it an smash it in?  Pics illustrate what I’m talking about.  Anyone have experience with these QD devices?

If you look close, that’s the crush washer on top of where it’s supposed to recess into.


Different angle.


Fuck am I supposed to do?

The crush washer will crush but make sure you time it correctly otherwise if you go too far, you can’t go back as the crush washer will then be too loose.

As for the barrel protruding not allowing the brake to go on, is the muzzle device for 338?  Is it not possible to use just a 762 muzzle device?

The video I watched showed the crush washer easily inserted into the area past the threads for the brake portion.  Basically where the arrow is pointing.  I’d have to basically smash and deform the crush washer (pointed at with another arrow) to get it down there.  I just set the crush washer on top to show how it seems too large.  Admittedly, I’m unfamiliar with Sig cans and MCXs.



Not sure if it’s possible to use just a 7.62 device.  That would simplify things.  I’m nearly positive Coregan? Coregon? Has posted a Rattler with a 338 can.

Basically without the taper adapter, the brake is running into the barrel crown.



This is what it looks like when using the taper adapter, I just didn’t get a pic.



I guess it doesn’t really matter on the timing of the brake as the can will live on the gun and it won’t be shot without.  If need be I’ll forego the crush washer.  Just making sure I’m not an idiot and missing something here.

If you find out the 7.62 srd muzzle devices will work with your can, I have a muzzle brake sitting around that I can send your way for free. Will mount without the need of an adapter in the back.

Let me try to unpack your couple of questions and to confirm I am understanding them correctly.

Are you saying that the threads on your barrel protrude too deep into the MD to mount the brake portion of the MD?

What is the part number of the brake you are attempting to use (the one you have pictured)?  Is it the brake that came with the SRD338?

It does appear your crush washer is the wrong dimension.  CS should be able to help with this - if they can't, I can get involved and get something worked out for you.

Thanks for responding.

It’s a 338 brake purchased new from OpticsPlanet.  I don’t have the package in front of me for the part number.  

It looks like it shouldn’t need the 90 taper adapter, as it mates up nicely to the tapered barrel.  After installing the suppressor mount portion on the barrel, the front brake portion seems to be hitting the crown of the barrel.

No taper adapter:


Would the proper crush washer make up the gap in the photo?

It does not bottom out if I use the taper adapter that came with the barrel.  I didn’t get a pic of it mounted on the barrel, but it looks exactly like this (without crush washer, just bottomed out on the suppressor mount portion rather than the crown)



The can should hopefully clear soon, about 90 days into eform, then I’ll have another muzzle device to try.  I also ordered a SRD762 muzzle brake today.  I’ll hit up Sig for a new crush washer.  

I’m just making sure I’m not missing something here.  Do these suppressor mount/muzzle brakes normally require the taper adapter to work?  Also, will the 762 brakes work with the 338 can?  It seems like they would.  It’ll only have .300 fired through it, so the smaller brake won’t matter.

Thanks again.

No, you most definitely do not need the taper adapter.  The taper adapter simply "converts" the tapered barrel to be used with non-tapered muzzle devices.  The taper adapter "creates" a 90-degree shoulder for those MD's - in your case, you would actually, slightly, lose thread area in using a SIG SRD MD.  

We need to confirm the part number MD you have.  Assuming it is threading on correctly, you should have:  SRD-338-58X24-B - but, please confirm that.  EDIT:  I can see in one of your last posted pics that this is the MD you have.  

No, the crush washer will not close that gap you are showing.  

Two Things may be in play here:
1) It appears you have the wrong size/diameter crush washer.  That's an easy fix.  
2) Your SRD MD may be out of spec.  Im still up in the air on this one, as I need more info.  Is there anyway you can re-install on your rifle, remove the brake portion of the brake - leaving only the base portion - then take pictures looking down inside the break/end of the muzzle?

Coregon is the fuckin man.  Great asset for us.  

This is certainly not a knock on Sig, more curious as to what the issue is.

Thanks again for the help.  Grabbed some pics.  Only thing that jumps out is more of the female threads showing when using the taper adapter, which is to be expected.

Package:


By way of comparison, this is the mount torqued WITH the taper adapter:


Also WITH taper adapter:


This is the mount torque WITHOUT the taper adapter:


Also WITHOUT taper adapter:


Probably not helpful, but here are the barrel threads.  I don't have a calipers readily available.  The barrel is a 9" .300 just purchased from Osage last week.

There’s not a ton of info out there, but from my googling it seems like an SRD338 can will mount to an SRD762 muzzle device.

I'm an idiot.  You have the wrong MD (I know, it can be confusing - see my first sentence )

You have a 5/8x24 threaded MD for a 338 rifle.  This is why the threads in your smaller caliber rifles are protruding through the mount.  

You can use a standard 5/8x24 threaded 762 mount with the 338 can - this is the mount you need.  

Apologies for not catching this sooner.  

@Subpar - I replied to your PM's.  CS will still be reaching out to you.

I got a cheaper/shorter K can with the hopes that this thing fits in my EDC bag suppressed, so trying to not do a QD or anything that adds length (or cost)

You can use a standard 5/8x24 threaded 762 mount with the 338 can - this is the mount you need.  

Apologies for not catching this sooner.  

@Subpar - I replied to your PM's.  CS will still be reaching out to you.

Got your PM.  Thanks a lot for the help in this and for answering my questions in the past.  

Problem solved.

Just wanted to follow up on this:

It was due to me not doing my homework and having the wrong muzzle device.  My fault.

Just got a call from Sig customer service.  They’re going to send me an SRD762 muzzle device gratis.  That should fix my problems.

Thanks again, @coregon and Sig.  appreciate you guys going above and beyond!

I just took an MCX Virtus Patrol in trade with the 15" rail.  Is there an option for a shorter rail on Concrete to match?  I like the look of the shorter handguards

Sent you a PM, I’ve got a rail that’ll work for you.

Help me understand, what is better about the G Charging handle with 1 latch versus the Sig handle with 2 latches?

It's still an ambi charging handle. I really like the Sig version. In fact, I have a Radian on the shelf, because I prefer the Sig. But I wanted to try the G.

The Sig version is much better at sealing gas. Dunno why folks opt for the G on the MCX (habit maybe?).

That's why the Radian is on the shelf.  If you're shooting unsuppressed like a heathen, then it doesn't matter as much.

Looks like MCX 11.5 exchange kits are back in stock on the Sig website if anyone is in the market.

I hope not. Mine is great at venting gas in my face so I grabbed the G because I'd read that it's better at sealing gas. Haven't installed yet but I can't imagine how it could possibly be worse.

Thank you! I finally was able to order one because of you! I double checked the site still said they had stock and placed the order.

Now we wait and see if Sig plays the same game they played after I ordered an in-stock 11.5 upper in May 2021... They were in stock, I ordered online, was charged, and my order was converted to a backorder with no ETA that I eventually cancelled.

Be interesting to know what cans you two are using.  Wonder if backpressure affects which ch seals better.

Can’t speak for them or the Geissele SCH yet (have one on order) but I’m running an AAC ranger 2 that was converted to omega mount by ECCO on a plan B/Cherry bomb and gas isn’t bad with the factory CH but it’s absolutely horrendous with the Radian CH. Worse than any DI AR-15 I’ve ever fired with a can. That thing will be going down the road.

From what I've seen, it's the latch itself on the right side. The Sig has one, the others do not. I don't know whether the larger handles on the G will help at all.

Now, if I'm shooting unsuppressed like a heathen, then any handle is fine.

[Last Edit: PGT_0673] [#50]
big thanks to @hiih8r for hooking up today to grab the shorter HG.  I put a spare stock on it, sights and T2 and calling this done (for now).  I'll get around to swapping a DA mount on it at some point to run a Sandman-K.
