Has anyone taken s P556 xI and made an SBR out of it yet? I've been thinking about it, but haven't seen or heard of anyone doing it yet.
|
|
yes a bunch have done the 7.62 versions to sbr. Mine is back at sig now to look over a few things but also my form1 has been pending.
is yours the rifle or pistol version? |
|
Currently, I have a 556 Classic and a 556R Classic. I've been thinking of getting a pistol upper for each and making SBR's.

Hi I have a p556xi that I sbr'd. It originally came with the sig brace and I was able to order the sig swiss style folding stock directly from Sig to add to it once my form 1 was approved. It literally took only a few minutes to switch from the sig brace to the stock without having to purchase a lower.
I hope this helps. |
|
I thought Sig was supposed to be offering 10" and 14.5" barrels for the 556XI?

I have a form 1 already approved but would rather buy a 10" factory barrel vs. chopping the original barrel. Plus I want the full 7.62x39 kit. |
|
I wouldn't chop any 7.62 barrel. There was someone that did a form1 rifle to sbr and chopped the barrel to 10" and it doesn't work. Sig must use different size gas holes in the barrels.

Duh, forgot about that. I guess you just have to order the barrel but I heard stories about sig not willing to sell short barrels to rifle owners. I doubt that is true though.

I haven't seen anyone do a conversion from pistol to sbr, but we have a factory SBR in the shop.

I think Steve has pretty much sworn off ARFCOM. I troll through here just to keep up with things and see what's new.
|

Is this SBR for sale or is it a rental gun? I may have to make an excuse to go up there and grab a burger and pet the Shepherd.
|
|
It is for sale the last time I checked. I haven't been in the last few days. Our MPXs did show up, so I am going to have to get in there asson as I get back from AT. But, do you really need a reason to eat the food and pet the dog?
|
|
The main reason I need an excuse is that it's about a 40 mile one way drive from my house.

|
Guys, why don't we take this to IM. It's getting somewhat close to advertising for my comfort.
|
|
|
Chopping a barrel was what I was wanting to avoid. I recently started looking at buying a 10" 516 upper to put on my AR since it's already SBR registered.

I've heard from a few people the 556R and 556xiR don't suppress well.

I have a 5.56mm Gas knob in mine. The 'adverse' setting is opened up a bit to make it run without the can, the regular setting is to keep it nice with the can. I built that gun long before the XI came about. I had to source soem 5.556 Patrol parts on gunbroker to build that one. |

I'm familiar with the non-xi 556es, and they have two styles of mounting stocks to the lower, one with an AR style tube, and one Swiss style for the folder. Looking on Gunbroker, all of the P556xi guns with aPSB look like the AR buffer tube style lower. How do you connect a folder to that? I'm assuming that you get a Swiss folding stock, and not a AR buffer tube type folder, like they use on some PSB guns. |

it was pretty easy to add the swiss style folding stock to the p556xi. My P556xi came with the non-folding sig brace. The hinge post was already on the lower. I used a punch and drove out the pin from the hinge post and the sig brace just slides out from the back of the lower. The swiss style stock came a little washer and replacement pin. Align the stock to the hinge and punch in the new pin. The great thing was that I didn't have to replace the lower. The same concept/prcess would work for the DDLES adapter as well if you wanted an AR style stock.
I hope this helps. Quoted:

Nice....that's the "R" isn't it? I see that's a LaRue mount, what model?

The problem with the larue mounts is first you need to decide what side you want the CH on. The throw lever will hit your knuckles if it is on the same side of the CH or far enough forward to interfere with the CH. |
|
Since I'm left handed, the charging handle would be on the right side. All I would have to is turn the mount around.
