I have a stainless 1-8 Lothar Walther blanc that I want to turn in an upper for practical shooting. (max range is 200 m)
Of course I am looking for the less possible recoil. (Brakes available in Europe are Miculeck,JP tank,Jp Cooley, DNTC FSH and even a few Rolling thunders)
From reading and searching on this forum I know that the rifle system is the way to go, but isn’t the barrel to short for this? (after threading and turning the finished length will be 16 inch)
I was thinking that maybe when starting with a gas port on the large side and then using a adjustable gas bloc one could make it work.Or is the intermediate gas system as Noveske uses for their spr a good solution. Last option is using the midlength gas system.
The lightest bolt carrier I have found over here is one from a Colt rifle (semi circel rear end) If needed I can still lighten it by machining. Buffer available are the rifle and standard carbine buffer.
I want to go with an adjustable carbine stock so my girl friend can use the same rifle.
Hope you guys can give me some suggestion on what works really well.

KAC’s midlength gas system for 16" barrels seems to be significantly longer (nearly rifle length?) than the “more conventional” Armalite type midlength systems for 16" bbls.
I have no idea about how the gas port diameters may compare, but I would like to know more about the reasonings behind KAC’s approach to the 16" mid system … and why it differs in the ways that it does.
Unless I read your question wrong - You should have no problem getting a mid-length gas system to work on a 16in barrel. I have a 1/8 twist 16in Sabre Defense barrel that works very well.
As far as recoil/brakes are concerned I don’t really have an answer for you. Sorry
Correct ,
the 16 barrel will work with the midlength system. I have read that a rifle system is smoother than midlength and that is my primary aim. Building the most soft shooting upper I can with this barrel.
I have read a bit about an intermediate gas system. It’s supposed between midlength and rifle. Developped for the SPR rifle by Noveske. I haven’t found anything on the KAC rifle yet. I’ll keep searching.
Maybe the intermediate system gives the soft operating
For a 16" barrel the only gas systems that willl work are carbine and midlength. For 16" I’d go midlength. The longer the gas system the softer the felt recoil.

I was using a SJC Titan muzzle brake which works extremely well for competition, recoil is almost nothing barely more than a Ruger 10/22 .22LR.
Before I added the Phase 5 Tactical bolt release I was using a 1.8oz carbine buffer. The first time I fired the rifle with that buffer I couldn’t even feel the bolt lock back when the rifle ran empty so I had to give it a little more gas just so I would feel it. The trick to lower felt recoil is lowering the moving mass, making the gun slightly muzzle heavy and using a great comp/brake. After adding the Phase 5 Tactical bolt release I had to go back to a 3.0oz buffer and adjust the gas system so that it lock back when empty. I had to modify the bolt release as well as it was too heavy and the gun cycled to fast for the bolt catch to intercept the bolt. I removed a lot of the bolt release weight using a milling machine and then refinished it with Norrells.
The problem with most brakes/comps is that they are very loud and when fired close to the ground they kick up debris and or dig a hole.
I shoot a lot of 3gun matches where they make the shooter shoot prone and roll-over prone and this makes for a mess.
The KAC Triple Tap doesn’t kick up much debris off the ground, while it’s not a true competition comp/brake it does an excellent job of lowering felt recoil and muzzle lift. It works better than many of the strictly competition brakes/comps I’ve used in the past. And it does this while being much quieter with less concussion to the shooter and bystanders. One thing I noticed is that the rifle feels smoother with the KAC Triple Tap. It’s hard to describe but it just feels smoother kind of just like when you get your cars engine tuned it just feels smoother.
I used this rifle with this KAC Triple Tap compensator at a 3-man 3-gun match this past Sunday in York PA. My team placed 1st in our division and 2nd overall. My two teammates were Dan L. using a JP Bennie Cooley Comp and Brett S. using a TTi recoil eliminator.
I see you had the same issues I have talked to Ken about this and i did the very same. to my P5 latch. he is making a new version
Gotm4,
That’s a beautifull rifle ! I have been reading and looking at a lot off pictures from you. I was hoping I could use the rifle length system but maybe I can get a soft shooting gun with the mid length system. I bought the rifle blanc as a 28 inch long one but had to make a 11.5 for a friend so this is what’s left of it.
BTW: The 11.5 runs great with a carbine system and an 0.078 port standard carbine buffer and spring. I based myself on your carbine dimensions versus your friend his Colt hread. H or H2 buffer are not available otherwise I would try them.
I would love to own a Titan compensator but Chris at CPWSA is a bit concerened about shipping me one…as I live in Belgium
