Re: Not enough barrel!!!!

Ecco threaded my cz75 clone like that and it's as accurate as ever (which is good because it was the most accurate 9mm handgun that I own).

Re: barrel porting question

I wanted to update the topic. I was able to dig a few bullets out of the berm behind my target stand today. I was hoping to find some of the 9x39 so I could look at the jacket to see if they're getting tore up real bad from the porting. No, it is not. You can clearly see the rifling, and the jacket ...

Re: 300 Blackout Integral Comparisons

The big issue with a piston, is the clearance over/between the piston and the ID of the handguard. Unfortunately, most handguards these days just has a small channel for a piston, which is kind of more like an arched doorway than a circle. That's the biggest issue. Basically, it's not impossible, bu...

Re: 9x39 project

I didn't use springs. I just made the inside tube that goes over the barrel long enough to fit between the back of my diffuser and tension to into the face of the rear cap. It took several passes on the lathe shaving the length of the tube until I was happy with it. But I got there eventually. I did...

Re: barrel porting question

Yeah, that wouldn't work like how I did mine. I understand why you had to do it differently. I never intend to shoot supers in mine either and didn't want to lose too much velocity while shooting subs so that's why I only ported it how I did. Sure, we can do like HK and make about 30 ports to drop s...

Re: 9x39 project

I'll try to explain how I held the inner tube in place over the barrel and under the suppressor tube. To be able to explain it though, I need to tell you that I made my own internal muzzle brake that screws onto the muzzle threads. I'm going to call it a diffuser for the rest of the conversation bec...

Re: barrel porting question

acanadian, I ported my 9mm integral barrel just forward of the front of the chamber. Maybe 1.5" ? I only made a single row of ports around the barrel, but it was enough to help port off some of the gas while still giving good velocity down range while still splitting some of the gas out of the bore ...

Re: 9x39 project

I have observed no accuracy issues whatsoever. The ports were shaving some of the exterior of the jacket for a while, but that seems to have settled down now and I suspect that it is going to continue to get better and be less with use. When I took it apart the last time, there were only a couple pi...

Re: barrel porting question

Thanks to both of you.

Copper mesh may help but I couldn't tell that it did much on mine. I even stuffed some aramid/Nomex material up in underneath of my handguard. The worst part of that was the smell of the stale powder smoke when I took it apart. Shew-wee it was bad.

Re: barrel porting question

I just wanted to update the topic and probably put it to bed. The jacket shaving is settling down now. It's quite a bit less now than it was initially. The integral can is done, and the portion of the barrel is not filling up with jacket shavings. When I took it apart and cleaned it, there were some...

Re: Schalldämpfer After-Burner

I had never considered internally threading the front cap and installing any sort of brake or anything of the sort. You would think that even having a long solid piece (other than the bore) may would even hold the gasses longer. Thank you for sharing that Historian. Also, check your PM box. I sent y...

I used double spring valve retainers in my first can if that qualifies as a step baffle in your discussion.

It sounds good.

It has held up well.

Re: barrel porting question

Thanks for the replies gentlemen. As I have mentioned, accuracy seems largely unaffected and good. My ports are between 7-10 inches of barrel. I can't really port nearer to the barrel with enough gas left to work the gas tube and the bolt. On the positive side, they are very small ports though. Abou...

Re: barrel porting question

That is true. When I made the gas port for the DI, I stopped at .109/.110'ish and I was surprised when clays and titegroup was fully functioning. As I said, it's a little weak there and ejecting about 5 o clock, but I think that it'll be about perfect once I get to make the can for it. I could open ...

Re: barrel porting question

The porting is working wonderfully where gas flow is concerned. With each pull of the trigger, a gas cloud suddenly appears around my barrel, so that's good and should work well in the integral once I get the approval signature. Currently, the port holes are about 1.5mm. I don't want to open them up...

Re: barrel porting question

It's not too late to angle it if I enlarge the holes a little more. This would elongate the hole similar to how semiauto shotgun ports look and was why I was asking. Though would it matter if I angled the bit forward or backward in relation to the muzzle. I would think angle it forward would round m...

I am wanting to ask you guys a question, which I hope someone may know the answer to. I ported the barrel with about 1.5mm holes, but they're shaving some of the jacket.

1-1/2 lb of weight forcing the bolt closed battering it and the barrel extension seem a little overkill?
