SHOT Show 2015 Pictures (From SMGLee)

[ALCOAR]

Negative, rather I used the term in a very complimentary fashion.

I've used the term "toy rifle" in the past to describe both a stock Colt 6520, and a stock SR-15 IWS feel.

A bone stock 6520 weighs 5.9lbs empty, and 6.9lbs w/ fully loaded 30rd mag.

A bone stock SR-15 IWS weighs 6.8lbs empty, and 7.8lbs w/ fully loaded 30rd mag

The Mk4 config. above weighs 6.6lbs empty, and 7.6lbs w/ fully loaded 30rd mag. Bear in mind the Mk4 rifle has a T-1/ADM mount, SF M300A + SR-07 tape switch.

Is that larger hole near the barrel nut an integral QD?

[RXM]

Yep. New rails have QD mounts.

Are there any plans for Geissele Rails for 7.62 rifles?

[MountainRaven]

Well, damn.

Might need to buy a new Mk1!

[HKfan]

Trident,

Any updates on the mk4 release? Still set for April?

[ALCOAR]

Does anyone know the height dimension (from top to bottom rail) on the MK4 rails? Also, are they using 7075-T6 aluminum for the rails or a 60 series aluminum alloy. I prefer using the thumb over the top rail type of grip on a RD sighted carbine, so the rail height is just about as important for me and my hand size as a rails width.

Here are the measurements for the height dimensions (from top to bottom rail) for all there variants of the SMR:

Mk1: 2.2415"

Mk2: 2.3125"

Mk4: 2.3130"

Are there any plans for Geissele Rails for 7.62 rifles?

Quite some time ago, I had ask about rails for 7.62 ARs, and was told that they are planning on offering these in the future. I wasn't given any kind of time frame for them though. I'm very confident we'll see SMR 7.62 models in the future, but my guess is that it won't be any time in the immediate future.

Trident,

Any updates on the mk4 release? Still set for April?

I've haven't received any release info on the Mk4 thus far, and I think the April date was told to others by the folks at GA.

I hope its very soon though!

[Brown_Bear]

Really happy with this rail and trigger

[Merle]

I just wish I could find one of the MK 1 rails in stock somewhere. If anyone knows where I can get one please pm me.
