OK, that looked really good -- don't tell me you've got a 9mm DI setup -- or might that be a piston? I love the shop rag handguard and the cardboard box handguard! Handguards are a problem for me since most of the piston systems are tall. I shaved the top off my piston setup so it would fit under those oval glacier handguards. The piston setup is at the pistol length position and I'm using midlength handguards so I can remove the top to take the thing apart to clean -- if ever necessary. I would love to see a short piston setup that could fit under a larger varity of handguards -- are you working in that direction? Marty has a barrel for me from a long time ago that I'm going to switch the piston system over to. Then I can get a better idea as to the Pro's of the piston system. Right now I have it on the 22 Reed Express carbine and that's not a valid test since it's all hand loads and already runs pretty clean. One thing I have to ask you is -- that DI gas system you sent me with the barrel is totally different than the one in the video. is mine a new type or old type? I like it because it fits under anything -- even that shop rag. Charlie

Not knowing what you have up your sleeve I was thinking you just might have a super short piston setup -- that 9mm ran really nice. Have you tried it with a more standard Colt type magblock and Colt style mags like C products or those plastic ProMags? The Promag 9mm mags actually work ok -- just don't load them to capacity. If you don't have a Colt style magblock I might know where there is one. By the way, I love that super low gas block! Just for Ha Ha's, back in june I sent Marty a picture of one I was thinking about but he told me you where way ahead of me. Mine was a little work intensive since the gas tube is brazed in place. Yours is way nicer -- I pitched mine. I would like to see more of the 9mm DI. Hope you get a chance to try some rounds in a Colt type setup. Does it run clean or does a lot of crud get back into the bolt and all? Charlie

my guess would be a far amount of crude since the DI 9s are running the super short gas system...........can't be worse then a blowback 9mm though, except having to take the BCG apart occassionally.

OK Charlie, you win ( Bowing in defeat ) Our super lows are just a pain to set up without a jig and jigs take time etc etc blah blah blah, but they do work I've got a colt system in the works, them Uzi mags are a PIA to load Tok mags work but we needed a little more incentive to do a Colt mag adapter . No, zero, nada on the crud ;D

No, zero, nada on the crud ;D I like the super low profile gas system -- I get the impression there aren't vary many of them. I think I can locate a used RRA Colt style magblock if that would help with the 9mm project. It just depends on if the fellow still has it. Just a little side note -- a long time ago I was thinking about a 9mm DI setup so I started with a modified Colt type magblock, loaded some 9mm rounds in a mag and tried it in my 7.62 Tok DI carbine that I had years ago. I had to do a little clearance work on the magblock feed ramp but the setup fed like a champ. What really bothered me was the darn 9mm (WWB, 115gr bullet) would fully chamber in the Tok. I figured it might be a good idea not to have too many similar components between the 9mm DI and the 7.62 Tok DI. Charlie

The super low is our std gas block and has been used on 90% of our conversion uppers. Compact and efficient. Just a lot of machining set up and steps, without new jigs and tools. I just recently started making more conventional blocks to try and reduce the set up time and I haven't decided which way to go yet. You should see the last one we did lets just call it The Industrial Gas Block. Stupid simple to make tho.... I've got a Colt set up and that's next on the list to try on the 9 Project. Tok mags work and would save an adapter/mag expense on the conversion. I might take a Pps-43 mag and put a spacer in it, but it works without it so what's the point... Put a handguard on the Tok piston last night Expensive and heavy, just what I'm looking for but, it works..

It looks really nice but I'm not into spending a pile of money on a special handguard for the Tok piston upper. I wanted to show you something in a piston that might fit under regular plastic GI handguards but I decided it's not worth it. It was based on the idea that Osprey uses -- very compact with the op-rod set on the top of the low profile piston chamber. I contacted Osprey about maybe making a pistol length unit but they said that due to the way it fits into an existing front sight base or gas block it is too long to be made in a pistol length setup -- darn.

I was always told there is no substitute for cubic inches. ;D

love2shoot, What brand and type of AR magazine where you using for long loads in you video?
I was thinking of using a C-products 5.45X39 mag or maybe a standard magpul.

it was a C-products 5.45x39 magazine. I do not have any 5.56 magpul mags.

Well, I got my new barrel with the gas port at the pistol length location. It's a 16" SS barrel and very nice. I tried the piston kit on the barrel hoping it would work with commercial ammo but nope -- I don't want to screw with the gas port size so I guess the piston kit is out on this one. I put the DI gas setup on the upper and it works just fine -- that's the way it's staying. I wanted this barrel to get back into shooting the longer 7.62 mini-whisper type rounds that I diid back when I had the original barrel. I may put the piston kit back on the 22 Reed Express upper but it shoots so good with the DI setup I figured why bother.

Tokarev with pistol gas system? What ammo?

Tokarev with pistol gas system? What ammo? My test ammo is S&B commercial stuff. I tried it with the piston kit and it would unlock the bolt but not eject. I went back to the DI setup and it works perfect. It may just be the piston kit I'm using but I'm more than happy that the DI setup works -- I will not be shooting milsurp ammo in this upper, it's purpose was to get back into the 7.62 mini-whisper type ammo. I don't have a suppressor so all my loads will be supersonic.
