I used to use a metal mod button.

Depending on how you grip the gun, you could also use a metal sling mount provided it's long enough.

Even the plastic mod buttons will suffice at adding rigidity.  I don't expect my lasers to hold zero on a PCC at 400 yards. :)

Trying to organize ammo in the garage cabinet and got bored so I thought I'd do a family photo of my Sig rifles...



I bought a SURG kit but it hasn't even shipped from EuroOptic yet, I need to contact them and figure out what's going on.

Decided to go all out. Got a legacy MCX upper and swapped the Rattler LT internals into it for the longer top rail.  No more XTN.

CSAW | LVAW


Getting a Lancer Carbon rail for the MCX later this week. Gave up looking for a SRD762ti, so I'll stick with the SLH for now.

@J11B would you be able to measure the ID of that? I'm also curious if it works on the OG rattler.

Rebuilding her. Had to part it out a while back. But still a registered SBR.
Just got a ILWT 4.25" on EE. Just did a quick function test both suppressed and unsuppressed and definitely had the grinning at the end haha.
Thinking I'm going to go with an A3 triangle stock just for some variety and the price. I got a coyote B5 grip but it puts my hand a bit to close to the muzzle for comfort so I think I'm going to have to find something different.
I'd like to eventually get it cerakoted in RAL 8000 but that will be once I figure out all the parts.

Gen 1 love.  Absolute grail gun for me and made it a reality!

But i just can't decide if I want an MCX.  I absolutely love the MPX but I'm nervous that picking up an MCX will be regretted in the future. And if I do get one should I opt for a second hand Virtus or previous gen or go with an LT?

I would go Virtus or Spear ... not that there is anything wrong with the legacy models ... but there is better compatibility between the Virtus and Spear LT ...

$1500-1700 … phosphate outer coated barrels are chrome lined vs nitride. I have a rare 16” variant of that … so if you find one … might consider it. The chrome-lined variants will demand a higher price.

Hope it works for you but pick and pluck has never been the answer me.  The last one I attempted was for a Pelican Air 1705 for my daughter's Geissele 11.5.  The thing fell apart before I got half way done.

It won't work in every case, but the Magpul case inserts worked pretty well for me.  Here is a link to someones set up.  
------> Magpul Inserts

The one I set up was neater.  It works better than you might think.  I used some E6000 adhesive to make a couple of things permanent, but the beauty of this is that you can alter the interior pretty well.  For instance, I made a space to add a S&W Body Guard II pistol in the case because I was not transporting magazines.  After I arrived we removed the pistol and made space for magazines.

You can cut the grid to the case size if you pick a kit that is about right sized.   It's coated Styrofoam (heavy Styrofoam).  It cuts easily with a plain hacksaw blade.  Once you have a grid you just plug the small segments into the grid to make your cutout.

If this doesn't work for you Cabela's carries extra case foam for one of their cases, you cut to fit.

Also figuring out the light position and keeping the surefire switch or going to a Modbutton for space saving.

Would also love a laser

Scalar Works makes some really nice compact irons now.  In standard height and 1.93" height.  I've got three sets and have been especially happy with their compact size and ease of adjustment.

Not sure I understand the question.  But I think you could simply use an AR lower (with Sig converter if you wish).  That is a question for SIg.

Hey y'all! I know that this is a long shot, but does anyone happen to have Gen 1 MPX FCG with the original trigger bridge that they would be willing to sell? I have been trying to find one for the longest time, but have not had any luck. :/
I am getting quite tired of destroying disconnectors due to trigger slap with my standard mil-spec triggers, but Sig CS has not been helpful with finding a replacement as they do not have any old stock laying around to be sold. Any leads on where I can find one would be awesome! This would be highly appreciated! Thank you all for your help!

Built an MCX upper for my ever evolving 300 blackout.

Tacops upper but with a 9" barrel.




Once I got it all assembled I didn't really like the girth or the look of the Tacops SD rail.

Sent the barrel to adco to get chopped to 6.75" and sold the Tacops rail and bought the Spear LT SD handguard.

I must be bad at google but I can't really find an MCX SD rail ID thread or posts about the various SD rails for MCX's and what their ID's are.

Is the smallest ID one the lancer? Then the biggest the Virtus SD rail?

As someone that shoots a full auto mac10 you learn a common issue with super short barrels and grips right at them, is the potential to shoot your support hand or fingers when opening your grip while shooting or having a malfunction of the grip where it can unmount or break off. That being said I went with an a3 tactical vfg that has a hand stop built into the front also made specially for the mpx
