on the fence with bloc II build

[robo]

I'm having high caliber sales do a 14.5 bloc II build for me...well mostly a bloc II. I'm on the fence about running either a switch bloc or a mk12 gas block. The rifle will be ran 50/50 surpressed/ un surpressed. I need some first hand knowledge and opions on either. Here's the specs.
- LMT defender 2000 lower
-lmt receiver
- lmt auto carrier
- lmt enhanced bolt
-Dd mid-length 14.5" barrel
- knights front and rear buis
- DS RIS II Rail
- Gun Fighter charging handle
- BCE 2.0 comp
- Gas block?????

Got this idea for the rail with the switch block from another thread. Since it wont fit under the DD rail, cut a small section out of the rail so you can access the switch, if I go that route...here's a pic from that thread.....and for some reason it won't upload.

And I have to add...high caliber sales customer service had been impeccable, any email I have sent to Kevin O' Neill has received a reply back with in two hours.

Run a standard DD, BCM, or LMT bolt, the LMT Enhanced Bolt will likely have issues with a 14.5" middy. The enhanced carrier might help it run better suppressed, but I'd simply suggest the normal bolt for better reliability unsuppressed.

Next question is length - why go with an SBR 14.5" when you can do a title uno and make it 16"... and a pinned 14.7" doesn't strike me as quite attractive, but if you've already got the SBR lower then you're golden.

The normal DD LP gas block will do - the only other considerations worth a look would be a maybe different barrel - Centurion's lightweight 16" Middy comes to mind (not as lightweight as DD's for profile), though what you've got aside from that is great.

HCS is GTG as well, so you're set there.

[ETA] Almost forgot - if you're willing to bridge the difference between a Block II SOPMOD and a Recce rifle, you can do the HCS 16" Recce barrel in that setup - not as light, but I suspect it would be an unparalleled tack driver.

I went with a 16" block II build and I just cut down the FSB on my LMT upper. I just couldn't justify an additional $200 for only 1.5" shorter.
