22arc versus 6 arc

[MaximusDecimusMeidius]

I can't stand it not having my reloading equipment set up yet

I am putting the finishing touches on this room and need to build another table and some shelving in the closet and a couple of sets of shelving and it will be my reloading space

it is taking me a long time learning how to do all of this myself lol remodeling a house from the 1950's but I'm single so it gives me a healthy hobby lol

"The short answer is yes, the long answer is we have multiple dealings with 22ARC running AE suppressors - we are launching a direct mounted barrel so you don't need their muzzle device or taper mount collar - and we are also offering an 18 Mk12 barrel -

Those are launching on the RTR line soon - probably late February if it was my guess"

From Craddock for MK12s if anyone was interested like myself.

That's the OPS Inc 12th and M24 models. I'd rather the barrel threaded 5/8-24 because the OPS brake outer threads are not commonly used for anything else firearms related. The brakes takes a lot of abuse too.

They already have regular barrels in 18" config for 22 arc

Those don't have the 12th model taper.

I’m missing the point i think. You want a 12th model taper threaded in 5/8x24 to not use a aem5 or 12th model?

No, unless I'm missunderstanding, Craddock is proposing a 3rd model profile and thread with a 12th model spacing. The threads on the exterior of the brake are instead cut onto the muzzle of the barrel, instead of using the brake.

Here is what I'm talking about; a barrel with the taper machined directly and 5/8 threads for the brake.

are there top shooters placing with LFGs now?

I started this thread in re to shooting guilty animals lol.

 

[BurtG]

had a hard time registering their hits visually through good optics when the

There’s a fair amount of people in this area shooting 223 for prs. The problem for them. Is it’s when most of you lose points because no one can see or hear your hits in some conditions

I never had issues with that with 6cm between 2950-3150

I wonder if it's going to be something like this but for gasguns. I love this for my OCM5 but you're going to need a .936" gas block to make it work.

 

[BurtG]

Is this available yet ?


How’s the RTR accuracy. Seems some people happy some people not. Almost similar to proof but proof seems to have more happy customers

I have secured a .936 24” 1:7 Krieger barrel. Now to start looking at parts, colors, etc.

Who profiled the barrel?

Ryan Beck at Base Camp Customs works perfectly with my OCM5s and OCL OCM HUB mounts.

It's cut wrong. The threads are supposed to be at the muzzle. The end of your barrel is reducing the blast chamber volume.

No it's cut exactly how I asked. It adds over an inch of barrel length with no added overall length to the gun with the suppressor added. It simply replaces the muzzle brake with added barrel length.

The volume difference between the brake and the solid barrel is small and likely makes little to no difference in suppression. If it's a big deal for someone he could turn down the portion in front of the threads to a thinner diameter to get that tiny increase in volume.

I fall into that category - running a 26" 1/7 twist bolt gun in .223 with 88 elds. It's frustrating, and I lose at least 5 impacts a match due to that. I'm not going to argue or contend an RO's decision. I just let it be. I made that choice, and I am going with a different cartridge this spring.

Lucky for me most of the shots at the matches I go to are under 1000yds and they put flashers on big/fixed targets that don't move much or targets past 600yds. Zero issues for me shooting 223 with 88s/85.5s and maybe a handful of times with 75s over the past couple years.

Probably but I’m really not interested in the direct mount platform is heavy already for an AR15 with a medium contour MK12 barrel. I just want a 22 arc mod 0/1 barrel so i can make a mod 0 in 22 arc and use my aem5

There would definitely be some weight added. Not that I'm itching for one but a Mod H style 22 ARC would be fun.

If you're happy with the performance that is all that matters. I can't remember if OCL retained the chamber over the barrel in the OCM5. OPS/AEM silencers have ports right after the threads that correspond to the brake ports. If you move the barrel forward of the threads you will block the ports. It probably isn't super critical to bolt gun applications but it adds back pressure. Blast chamber volume does have a significant effect on sound performance too.

On the OCM5 it doesn't block the opening that leads to the additional volume towards the back of the can. Just forces the gas coming off the blast baffle down the gap between the additional barrel length and the suppressor tube. The AEM5 is different... That gap is smaller at a point but not closed off completely. That may make a difference but IDK.

I just know that on my 16" 223 bolt guns the OCM5 with that machined in mount sounds great for as little length that's added. If someone wanted to stop the barrel at the threads for that additional volume they could but Idk how much additional suppression you'd get.

Also, if you're trying to meet the minimum 16" to avoid SBR like I was you'll be adding 1.3" to the overall length of the setup which for me defeats the idea of the build. Which is keep the build as short as possible while using the OCM5 or OCM HUB mount.
