We are selling our lake house and close on 6/22 and the wife told me I should buy a new gun to celebrate and i really want an HK MR556 A4. I’m trying to decide on the 16.5” or the factory SBR 11”
Pros and cons for each?

I have rifle length and carbine length AR’s and also some SBR(non-AR) rifles already

I went with the 11” pistol, which I SBR’d (this was before the factory ones were announced).  They are somewhat heavy guns, so the shorter barrel is a lot handier.  Plus, I wanted to run a suppressor, which adds weight and length.

All of this!

Warning, I sort of have an SBR addiction.

I’d go for the factory SBR and get a nice quality suppressor at the same time and tell her it was a package deal.

To me, the real benefit of a piston gun is an SBR or can use…

Only down side, to me, is it makes it more difficult to sell, if you no longer want it
I tried that whole cancer thing. It wasn't for me. Good Riddance.

Theyre definitely not for me, but if I had to choose I would go with an SBR. One good thing I can say is they're niche enough that they'll hold their value, unlike 95% of ARs.

I went with the MR556a4 11" pistol. What I did was pin and weld an extended flash hider to it to make it a legal 16" rifle. I really like it so far and enjoy shooting it.

If I had to guess XPS3-0. The only difference between XPS and EXPS is that the EXPS has a built in quick release lever. XPS just has a cross bolt screw mount.
I have one like it on my G$ rifle.

Yep.. XPS3-0
Now with more political fatigue.

Actually it’s a XPS2-0.  I didn’t need NV and would rather save the money over the XPS3.

the XPS is also a bit lower. like 0.2 or something. my XPS3 on a OG unity eotech riser is right around 2" which I like under nods quite a bit.
