98Z5V Posted Friday at 03:36 AM Report Share Posted Friday at 03:36 AM @blue109... So, first, brother... The Burn It Down gun ended up with a light on it. PID, you know. If you're gonna burn it down, then know your visibility range, right? So, I thought to myself - I better start looking for the NEXT barrel, because this thing isn't gonna last forever. Buy a backup NOW. Get on KAKs website, set my search criteria for their 12.5" barrels... Replacement is $119. Cool. But wait... What's THIS?!!? They have a stainless 416 barrel in a 1:5" twist?! WTF? What is THAT for? https://kakindustry.com/5-56-nato-12-5-ar15-barrel-stainless-416r-1-5/ Suffice to say - we're gonna find out... Quote Link to comment Share on other sites More sharing options...

I have 3 different 12.5" guns that will do 850 yards all day long. 6.5 Grendel, 6 ARC, and 22 ARC. I THINK that KAK is making this thing as a super-fast-twist in order to over-stabilize the 5.56 heavies in order to get more distance out of them. I don't know. I just found this barrel tonight. I'll call KAK in the morning about this thing, and find out what the deal is on it, why they made it. One way or another, I'll get one, and find out. Maybe it's made for 88s or 90s? We gonna know soon... 😁 Quote Link to comment Share on other sites More sharing options...

I used to use the 510 over 6gr unique for 45/70 but I don’t think you could fit 6gr in the .556 case Edited Friday at 04:12 AM by AngelDeVille Quote Link to comment Share on other sites More sharing options...

Now, wait a minute - are you talking about 5.56 here? The Hornady 88gr ELD-M is 1.240" long. The Sierra 90gr HPBT Matchking is 1.171" long. That just turns this into a math problem, if the case length is 1.760". and the loaded length for a mag needs to be 2.260"... Quote Link to comment Share on other sites More sharing options...

Are the bullets still in the neck when seated or do they intrude into the case body? I’m not a fan of that myself but whatever works.

Measure one of your 55s, and run the math, brother. It's real... Every single military tracer, every M855 green tip, all the Mk262 77gr issued ammo - the base of the projectile does extend into the case body. It's not a big giant deal, and is common on every cartridge ever loaded. I don't understand your phobia about it.

It's not a big giant deal, and is common on every cartridge ever loaded. I don't understand your phobia about it. It not about a phobia, it’s about at what point do you change calibers and at what point do you change the porpoise of the firearm. boattail into the case body is much different than almost filling the case body 147’s in my AR9 perform much differently than the 147’s in the the AR10 I'm interested in how the 1/5 work with the 90’s and also the 52/55/62. my 300blk shoots well with the 110’s and the 180’s I’m almost out of, but I think I will focus on the 110’s. I would imagine If the 1/5 5.56 gave a similar performance to the 110’s of the 300blk I may switch barrels and replace my 300blk with another 5.56 with a 1/5 barrel So many variations of the same calibre, so little time… I am thinking of picking up this barrel, as I have a side charging upper collection dust and haven’t decided on its purpose. And I think I may start breaking down my 300blk. Quote Link to comment Share on other sites More sharing options...

Beat me to it, get one, and test it out before I do. Otherwise, sit back, grab a beer and relax, and wait until I figure out why they did this. Or get one, and figure it out before I do.

98Z5V Posted Sunday at 04:24 AM Author Report Share Posted Sunday at 04:24 AM I can tell you this much - a 5 twist will blow up lightweight bullets. They won't be able to handle it. Too much rotational speed for those fuqrs, with the speed they travel. This was made for heavies. And that's probably the reason it's short. Stabilize heavies from a short barrel. But - get one and shoot one of those 52s through it, and let us know what happens. Quote Link to comment Share on other sites More sharing options...
