I'm gonna order a 6.8 barrel this weekend and wanted you guy's opinions.
I'll be getting an 18" threaded or a 20" target crown. Haven't decided with one yet....
I've been reading that the 6.8 runs best with the mid length system BUT I'll be using an adjustable gas block on mine. Does this mean that I can get the rifle length gas system to run reliably?

Unless you are going to use a suppressor and need threads to attach it, go with the target crown. The 2 inches of muzzle device gain you nothing in the ballistic department. Even if you only gain 50 FPS its an improvement that's free. Not to mention the cost of the muzzle device.

Thanks Ritch!
Idk that I'll ever run a suppressor, I was worried that the 18 might have a little too much blast/noise and thought a linear comp might cut down on some of that. The more I think about it though, the more I think a crowned 20 would make me the happiest.

But if your barrel is going to be that long anyway you might as well reap the benefits. Take the money you saved not buying a comp and buy yourself a set of dies

Would you pick your 20" over again? Now you I'm thinking that maybe an 18" with target crown would be the way to go....
Damn decisions!

I too am looking into a new barrel this weekend. 20% off can't beat that. The only thing is most of the really interesting calibers are not on the webstore( 243LBC, 6X6.8,). I am debating on the 6.8, 300 blk,04 6x45mm. An 18" 6.8 target crown is what I am thinking too. Not too long to maneuver but plenty of barrel to make a good shooter. I just want a good deer getter at close range( 400 yrds or less)

All
I am thinking of building a hog rifle for use in Texas and plan on an 16 inch 6.8 SPC barrel. I will be seeking advice on lots of things and mid or rifle gas system is one of them. I see BHW makes both and I assume for good reason. Advice?

Mid length is the recommendation I have see the most. I think that is what I will go with. Finally a decision on something.

Midlength gas for 16". 18" middy has excessive dwell time and is harsh. A 20" barrel with rifle gas is softer than an 18" with rifle gas and a larger gas port, even though 18 is handier. It is a pleasure to shoot 20" rifle gas suppressed. Always get a target crown. The last moment, when the bullet exits the barrel is critical. I've seen FAL barrels with pitting in the last few inches, cut and with target crown, shoot amazingly better.

I'm on the fence about this as well. I'm committed to an 18" barrel, but I'm also committed to an adjustable gas block. My manner of thinking is that I can always throttle back the block on the Midlength to get equivalent purge (even though it has longer dwell time) to the rifle length gas system, but I could only open the block so far with a rifle length, so without upsizing the port and tube, I have more versatility in the mid-length.
I guess in other words, I'm assuming that I can use my gas block to make a Mid behave like a rifle, but the reverse may not be true. Anyone have experience to confirm or disprove that theory?

You are exactly right. 18" midlength gas is the correct way to go. Rifle length gas on any 18" barrel regardless of chambering can be problematic.
