SBR length with suppressor opinions

[muddywings]

Ok,
So should have a trust set up soon so now I really need to decide what I want to do here.
Want:
SBR w/ suppressor for HD, SHTF, and because I want one.
Plan:
build it over an 18 month period starting with the SBR paperwork followed a few months later with the suppressor paperwork
Thoughts:
Again, this is more of a "I want one" gun, then any real need, but it will be the home defense gun. I'm leaning towards a simple screw on suppressor as I don't see me taking it on/off a lot. I don't think I want to pin it to get to 16" because I never say never.
Reaching out and being somewhat accurate at the 200 yard range would be satisfactory for my intentions
With that....
Questions:
11.5 or 12.5 barrel??
What suppressor??

I'm leaning towards an 11.5 for compact size and don't want to go lower than that but to be honest, I don't know if adding in inch will drastically improve performance while loosing some in the house maneuverability.
I'm leaning towards a YHM Phantom (looking at Silent Precision website) for cost reasons and because I don't really feel I need to go overboard with it (at this time...haha)
I really don't want to long of a can keeping the CQB concept in mind.
Anybody out there give this noob some advice before he fills out his form in a few weeks for barrel length?
(I'm buying a house at the end of the month so I don't expect to be sending in the paperwork until early september.)

Home defense? Are you going with a 300 BLK round to keep things subsonic?

11.5
this is a 11.5. currently running a AAC 18T A1 style f/hider and (not pictured) M4-2K suppressor.
My suggestion with NFA approval time running 11 months, EASY, submit BOTH at the same time. It's $200 more than your budget might allow however 11 months!! Elephants gestation period is shorter

If you're building it.. Go 300blk.

220g sub loads w/ a suppressor all you hear is the bolt slap.

I've got 5 stamps waiting currently.

I blame triggerhappy. He's a horrible influence

You're not going to see too much difference between an 11.5 and a 12.5 when it comes to maneuverability in a house. Both barrels should easily be able to make hits out to 200.

If you want, I'll give you a shout when I get home in a couple of weeks and we can hit the range so you can mess around with a 11.5 with a Gemtech Trek (thread on) and a 10.5 with a SF 556.212 (QD).

That's a really big house!
