Hey all,

First time, long time here.  I have nobody to show off my Sig to, so I figured I'd post a couple of pics here.  I'm way happy with this "rifle".  I did some paint work on the etching as you can see, I also painted the "safe" white" and "fire" red. I added the new sight.  It came with the Sig red dot, but for some reason I just hated it.  I also added the Fab Defense AFG.  Anyways, I hope you dig...if you have any questions or suggestions, I would love to hear them.  I need a new muzzle device...so yeah.  Later!  http://<ahttp://i102.photobucket.com/albums/m87/crying1986/SigP556_zps8b175041.jpeg</a>" />

What muzzle device would you guys put on this thing?

I'm waiting for my brace. Did yours come with the brace or is it one of the older ones like mine that came without an extension?

Got my tube tonight and put the brace on, along with a Holosun red dot.

Oh hell yes!!!!!!!

I LOVE the way it feels!!!

How did you get that end cap off the receiver, so you could install the tube?

Good question! I was going to make a tool to do it but after I saw the ATF letter I got a little too excited to wait. The cap just screws off by turning counter clockwise. I used a nail-set punch and small brass hammer (would be a little better to use a brass punch) and gently tapped on the side walls of the two holes in the cap until I was able to turn it. No need to use a lot of force--it's not Locktited in. Just a bunch of gentle taps to get it turning. You don't need to destroy the cap. Mine is still perfectly usable. It has a little bit of deformity on the sides of the holes but no big deal.

Ok, thanks. I guess I don't need the air chisel and blowtorch after all.

No blowtorch for sure! Here's a pic that kinda shows what I did. In the pic I have a Glock disassembly tool but I actually used a nail set punch.



The idea is to get something on the sidewall of one of the holes lined up so that when you gently tap it repeatedly, it puts a torque on the cap that will make it move counterclockwise so it unscrews. Be gentle and switch back and forth between the holes. Mine, which I bought new, was not Locktited so it was not much effort to get it off. It does ding up the sidewall of the holes a little but the cap is still usable, as you can see.

For those of you who think I was a dick for using a cheesy way to get the cap off, I plead guilty. I was going to make a proper tool for the job but after seeing the ATF letter, I was too excited to wait, so bite me!

ETA: Obligatory pic:

I used a large pair of vise grips and it came off without to much force.
If you want to save the plug. You may want to go with some rubber material between the jaws.
My plug had some gouges from the vise teeth.
