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

[badkarmaiii]

What are the specs on your rifle? Sounds like promising results.

DPMS G2 Recon with .8 diameter barrel.
Scope was a Diamondback Tactical FFP but I just ordered a Leupold VX-R Patrol 3-9x40.
Also got the new bolt and firing pin from DPMS.
Rifle is 7.2lbs without optic or can.
The SLR handguard shaved a lot of weight.

Been reading with interest for my next build. I take it there is little to no real advantage to a barrel longer than 16" for the 7.62?

I gotta say my Colt CM with 18' barrel in 6.5CM is a gun that is worth consideration. Sub MOA all day long, and very handy. I have a Burris 1-8 with offset RDS. Its a badass gun I rarely shoot.

I apologize if its already been said but I couldn't read the entire thread.

The 6.5CM is a helluva round, but I just think it's threshold for velocity is commonly believed to be 18". Seems like your example would be a perfected, or enhanced SPR. Basically improving upon the light precision 18" 5.56. That it most certainly would do with flying colors.

Strictly speaking for myself......16" is most certainly my limit. Any longer and I might as well just go with a 6.5CM barrel discussed in the previous two replies.

Just my 2cents.

Which is why one could consider a 24” LMT 6.5 Creedmoor barrel and wack it off at 16”-18”, giving it a rifle length gas tube. But then hopefully, LMT is working on it...

Why the RDS with a 1-8 scope? Do you not find the 1-8 works well enough at 1x that an offset RDS is better? That is pretty damning of the 1-8.

Not that I'm disagreeing with you. I have an Accupoint 1-8 and a Leupy 1-8 and they do OK at 1-8, but when the local rifle match is more of a pistol match, we switched back to T-1s on our run&gun rifles.

IF I were going to run a RDS, I'd think about a 2-10 or 3-15. Love a 3-15 on my JP 18inch 556 gun and my LMT MWS, but it really is too much scope for most of what those guns are for. Better for paper shooting than moving around and small targets.

Just a bit of velocity...

Right. For something like 5.56 or 7.62NATO, there's not much point in going beyond 16-18", at least not shooting inside 600yds (which is the maximum at my local range).

If you're looking at a hyper-velocity round like 6.5CM (or .243, or whatever), then you're giving up a lot of oomph (and creating a lot of blast) by cutting the barrel short.

Can switch to RDS in a pinch if a target suddenly shows up while you're zoomed in. Also a handier back-up sight than irons often. If it's an actual offset position, rather than just a 1200 piggyback, can also be used easier when the gun is canted compared to trying to get behind the scope.

Excellent link, just what I was looking for. Thanks!
