Perfecting the Recce concept: The case for .308/7.62

[Dave L.]

But I think you can ditch your muzzle brake; it's not needed IMHO, and will make your future build more pleasant to fire.

May not be needed, but for my 16" 7.62 build I chose the Surefire SFMB-762 SOCOM brake. I prefer to keep the weapon as steady as possible for the followup shot(s) and I'm planning to get the can for it down the road.

My issued SR-25 has the 30cal version of the Triple Tap. They brake is absolutely amazing but I'm not going to spend that much on a brake for a personal gun (even if one could find one available).

At this time, early 2013 best o breed consist of
16" 7.62 gas gun, light as possible, 1-1.5moa (better recoil characteristics than piston guns)
3-18 compact luepy tremor2
T-1 @ 45degrees with the light svelte KAC mount
A muzzle brake/device that permits self spotting

This get you 0-1200m fast



And if you think the old KAC 7.62 triple tap was good, the new KAC MAMs crushes it.

At this time, early 2013 best o breed consist of
16" 7.62 gas gun, light as possible, 1-1.5moa (better recoil characteristics than piston guns) - check
3-18 compact luepy tremor2 - check but with the H58 reticle
T-1 @ 45degrees with the light svelte KAC mount - Dueck Defense offset irons, kind of check
A muzzle brake/device that permits self spotting - now that my MWS sports a SF Socom brake, I'll have another check

This get you 0-1200m fast



And if you think the old KAC 7.62 triple tap was good, the new KAC MAMs crushes it.

Other than lightweight, I think I have most of those bases covered.

I really appreciate this discussion.

One question--are there any considerations that come into play here for twist rate given the 16" barrel instead of 18-20"? I know KAC is currently at 1:11 with the SR-25s. Wondering if that is the sweat spot for this type of build and if there are any thoughts of using 1:10 in this application.

3-18? For a Recce?

3-18? For a Recce?

It does seem like a bit much, but at least it has a 3x low end.

One of the understood aspects here that's paramount to the case for a .308 Recce is the fact that it increases your max effective ranges out to and potentially past 1k.

Many people wrongly believe you need telescopes to put effective fire on torso sized targets @ 1k..just like you need 20-24" barrels, however that said, you still do need more than your typical 1-4/6x type optic for reliable, repeatable success at these ELR distances.

I consider 10x to be the true minimum power required for a 1k capable Recce.

So now it becomes a true balancing act....weight/size : performance/magnification ratio. How much are you willing to sacrifice in terms of scope profile size, and weight in order to gain an optic powerful enough for the job at hand. Note that everyone is a bit different, some like loads of magnification on a target....some like as little as possible. There isn't a perfect one size fits all magnification for this configuration.

When analyzing my own recce glass needs, I found that the nxsc 2.5-10x24 offered me by far and away the best weight/size : performance/magnification ratio.

Leupy saved it's ship imho with the MK6 3-18x. Nothing they have done has shown a pulse in many years, and they failed to innovate or even listen to their end users...however something radically changed with regards to their MK6 model.

It's a true LR capable optic....not just some low variable powered optic half assing @ 1k.

I would put it at my # 3 position for perferred Recce optics....

1. NXSc 2.5-10x24 mil/mil z-stop

17 oz / 9.9"

2. March Tactical 1-10x24 Illuminated MTR-2 / Mil z-stop

18.7 oz / 10.4"

3. MK6 3-18x44 mil/mil z-stop

23.6 oz / 11.9"

4. NXSc 2.5-10x32 mil/mil z-stop

19 oz / 12"

5. NXS F1 3.5-15x50 mil/mil z-stop

30 oz / 14.8"

As always, geat post, Trident.

When designing your RECCE, the most important thing isn't your optic, your caliber, or your barrel length. It is analyzing you Area of Operation! A 1000 yard gun isn't worth a shit in an environment that doesn't offer a shot over 500. And the opposite is true. Just take the posts here as guides and recommendations and not gospel.

Not noted is the Luepy mk6 is FFP / F1 whatever you want to call it, and available with Horus options. So one can shoot 0-1200 w/o spinning dials, fast. One can shoot 500m in 20mph Left full value, turn 180 and shoot 1200m in 30mph Right full value.. and hit.

I have one of the handful of individual purchase NF 2.5-10x24 hash NP-R2, illuminated, original "spec-war" marked optic. It is excellent glass for the size and weight. Probably the best.
