​The pin had to be filed down to fit into the lower.

yeah I saw that after I encountered the issue.  DOH...

  I know.  I was just showing how the upper is supposed to slide into the rail so that when you screw down the locking tab screws, they tighten against the side of the upper.   The barrel nut is what holds the rail in proper alignment. 

I checked their website at the product description….Our SMR MK1 is designed to fit the M4 Carbine and all mil-spec AR-15 variants.    Doesn't say anything about billet uppers.. :(  I should have done some more googling…..

The upper and rail is mated, but this is without the barrel nut.

You can see that the upper has too much material to slide under the locking tabs. there is about a 1/2inch gap between the upper and rail since the rail cannot mate up against the upper.

Yeah. I'll get some pics up. Gotta upload them to photobucket first. But before that, I'm going to try to relieve my frustration by stuffing myself with some Mexican food first.

Very very little.  it may only need to be one on one side.

If anyone knows a good machine shop that can do a small job like this, let me know.

the mock up looks amazing.  That rail is so sexy and made well.  So disappointed… :(   I've got the lower completed, but now i gotta figure out what I'm gonna do.     If I machine the lower, i wouldn't have to remove much and the machined part would be covered up.  I don't think i can machine the rail.  There very little material on those locking tabs.   I'll put up some pics later

well i got the lower/upper in today.  The matched billet set is amazing. The fit between them is incredible with absolutely no play, even without the pins.       However, when doing a test fit, i learned to my disappointment that the Geissele SMR rail will NOT work with the Mega Billet upper.  The locking tabs of the rail slides over the upper and there is too much material in the billet upper to fit.  F*CK!!!!   What to do….  I don't want to use another upper so my other two options are to find a machine shop that can machine out the excess material or use a different rail.

Anybody around Nashville have a upper block or barrel extension rod that I can borrow for my AR build?  I did my first build without one, but it would be nice to have one for this build.   PM me if you have one that i can borrow.   Thanks    

Still waiting on the Upper/Lower. Hopefully tomorrow. In the meantime, I had some time to put the gas tube in to the block. Little painters tape to protect the gas block, leatherman to hold and start the roll pin, and a hammer and 1/16 and 3/32 punches to drive the pin in.

Yup, i just wanted a fast trigger.

Yeah I was teetering between the SD-E and the SD-3G but didn't want a two-stage. I don't do much bench shooting either so I went with the SD-3G.

Something I've always wanted to get into but never have. I'm guessing they have certain regs on what you can use?

I went from a 7.5" Noveske Diplomat SBR on my very first build so this thing should be much flatter shooting.

i looked on their FB page and they don't have any information on ETA.  Their website doesn't show any information on release dates either.  On the V1, I believe the detent pin has to be pushed in to change the adjustment screw.  The V2 doesn't need the detent because it a click adjustment 

they are coming out with a gen 2 version that eliminates the detent pin.  The adjustment screw is a set screw that clicks.     http://youtu.be/ykukUFgC0R4

ya i got the syrac adjustable block

Five pounds?  whats your setup?

its gonna be a first :)
