What kind of groups are you guys getting with your mid-length uppers at 100yds?

What barrel (i.e., make) do you recommend for greatest accuracy?

Thanks

Well one day my neighbors dog wandered through my property out about 250 yards...

about 1/2" @100 yards with BH 68gr MHP with my crappy beater burris 4x.

Plenty of nice 16" midlength barrels to choose from for sub-moa:

Denny's recon
WOA recon
Compass Lake Douglas or Kreiger barrels
Pac-Nor stuff from various reputable vendors including Noveske

Lots of people report sub-moa from RRA barrels as well with good ammo....

Which is better? Depends on who you ask. My opinion (worth what you paid for it) is that you can't go wrong with any of the above. Spend what you feel is in your budget and shoot a lot. More often than not, it's the carpenter not the hammer.

If I really try .75MOA 5 shot groups. As long as I can make the 6" steel plate ring at 300yds I am more than happy.



I recommend Denny's Recon barrel for the most accuracy. A good trigger and clear optics also help.

So after you shot your neighbor's dog were you man enough to go tell him that to his face or did you just go home and brag about it on the internet.....which one is it killa?

Simply pathetic. Too bad YOU didn't ND on the way home.

Wow, some people just can't take a joke.

Question about gas system length.


In the above photo it appears to me that as the Barrel length increases so does the length of the gas system. I can't tell by the picture but I'm going to take a guess and say...

24" = Rifle
20" = Rifle
18" = Middy
16" = Carbine

What say you

I reload for my 16" bushy v-match, it'll do .5's or less with most any bullet. Sometimes it takes alot of experimenting with different powders, but I usually get there.

IMO, not matter the length (rifle, mid or carbine) of the gas system, it's still the barrel, ammunition and the operator that determines accuracy.

What say you

The bbl length is not necessarily indicative of the length of the gas system. Here's a more specific rundown for each gas system:

I have never seen nor heard of 24" AR with anything other than a rifle length gas system.

I have seen 20", 18" and 16" ARs with the rifle length gas system.

I have seen 18", 16", and 14.5" ARs with the mid-length gas system,

I have seen 16", 14.5" and shorter bbl ARs with the carbine length gas system.

I know, what I was asking about was SPECIFIC to that posted picture. Can you tell by that picture what the gas system length is?
Link Posted: 1/20/2006 10:58:38 AM EDT
YES! Absolutely. You got them right. Unless there is a little dissipator style trickery going on, you can tell by the position of the gas block.

My 14.5" Noveske AFGHAN barrel with mid-length gas shoots about 1/2 MOA.

A better question may be "how reliable are your middies?"

Its curious that you can put the gas tube up and down the barrels length and not be suspicious of its reliability.

But then again, I'm no engineer/weapon tech.

Comparing carbine to midlength gas, the midlength gas system has a lot less port pressure and puts less stress on the bolt while there is higher chamber pressure. In other words, a properly built midlength should have better extraction reliability than a properly built carbine.

I can do 2 MOA with M193, Aimpoint and heavy trigger from my MRP. I bet with good ammo, scope and trigger it would be a 3/4 MOA gun.
