Thinking of rebarreling my old 20" H-bar barrel, maybe using a les baer type M4 16" bull barrel upper.

How accurate would a 16" 1/8 twist match bull barrelled AR15 be at 500 meters, using 75gr-77gr compared to a 20" H-Bar barrel? Is the 16" barrel stiffer than a 20"?

A 16" bbl is stiffer than a 20" bbl only if they are the same diameter.

You could try the 16" RECCE type heavy match barrel with the mid-length gas system. It's performance is 1 MOA or better.

Take a look at ADCO's website and click on Custom Building tab.

You could also contact them by e-mail on their website if you would like something else.


I also got rid of my standard grade HBAR and I'm currently building my 16" RECCE upper half.

Good luck.

I have a 20" H-Bar RRAand a 16" Bull Oly Arms that I use for hunting coyotes and general critter control. I genearally grab the 20" because if I don't have the opportunity to put ear plugs in the 16" is incredibly loud and will blind you at night. The 16" handles, carries and balances a lot better than the 20".

If it's going to sit in a safe and get shot off of a bench, get what ever floats your boat. If you are going to hunt with it, I'd get another 20" or compromise. For what it's worth, I can get 1moa with both. The 16" Oly will consitantly shoot 0.5 moa in the hands others.

ADCO is awsome. I use them for everything now. You get what you want and you get it quicker than you would think possible.

A shorter, stiffer barrel is usually more accurate. However, at 500 yards, the loss in velocity maybe telling, especially with heavier bullets.
