Thanks crow hunter, if they were able to get one they'll be able to get others.

Glad to help.

I saw where Grant posted it and thought I would share.

I don't know about their .308's but their .22 uppers are fantastic and excellent service.

Dont forget to check out the sig 716, been hearing good things about them.

I have a DPMS LR 308 Oracle and love it. The DPMS Recon comes with a lot of what I put on my Oracle. I have 200 rds down the barrel and never had a failure of any type. Plus it's a sub MOA out of the box!! Here's a couple of targets and I'm not the best shot anymore at 64 years old. On the TAP FPD target the 4 shot group in the bullseye measures .655". the two "4" shot groups in the AMAX target measure .655 for the 3 shot small group by the bullseye and .757 for the other 3 shot group. The recon should do this well or better out of the box.

How about a SIG 716? I previously owned a Bushmaster LR308 MOE 16" mid length carbine and the fit and finish on the SIG is far better.

In reality, the long action ARs are pretty impractical in the carbine format as you get all the extra weight of the platform coupled with the loss in velocity of a shorter barrel. If you must own the platform in 308 buy a full length precision gun as the 16" version really doesn't have any advantages over the 5.56.

Here is my SIG716 with a pic of the old Bushy below.

Playing around with Hornady's online calculator, it looks like their 168grain match ammo should stay above 1200fps until past 800 yards, when launched at 2300fps. Correct me if I'm wrong, but accuracy really drops off when it drops below supersonic (just under 1200fps at sea level). So, other than having a greater drop to compensate for and less energy at impact, why would 16in barrels perform so much poorer?

16" barrel doesn't perform poorer, that's just just his opinion. I completely disagree. Despite losing SOME velocity, it's still quite potent and capable of long range. It's 3 times the bullet of a 5.56, and 5.56 loses velocity out of 16" barrels too. My 155 grain loads are 2650 FPS at the muzzle out of my 16.5" P-308, same loads clocks 2850 from my 24" bolt action.

Yeah... you're correct. I just reread my comments. The US Army competition team has pretty much proven that barrel length is irrelevant within 500 yards.

So the quality of the barrel is probably more important than length. I still prefer my SIG over the former Bushmaster...

If I was going to do this all over again I would buy a POF with a 20" barrel.
