Just puled the trigger on a 45acp gas/DI upper. It works
 10.5" brl. Running Federal American Eagle & PMC 230g HB. Standard carbine buffer & recoil spring. Complete lockback with room to spare. Cases were tossed about 6' More to come. Smoke em if you got em!

The brl is just rough turned. I was convinced that it wouldent work. At least that was what I was told. I will get some pics as soon as I finish. I am turning a 16" 45acp brl as we speak. I keep going out back just to see if it still works............................. Yep, still running

Another success for Mr. Williams... Cheers. Thanks Jay. I need to look at my options with this gas system design. What I did must improve the system because the 45acp @1800K psi shouldent work in the AR. Today I am going to finish my 16" brl & set it up to run 45acp with a no weight buffer/reduced power spring. Then fire 45Super with the stock buffer/spring. If this works it will make for a real nice upper. A plinker/hunter combo! FunBobby, I need to finish the brls first.

Well I just finished testing the 16' brl. With a no weight buffer & a cabine spring 1.5" shorter than stock the factory 45 Fed/PMC 230g HB gives a comlete lock back & cycles fine. I installed the std carbine buffer/spring. I dont have any factory 45super so I chose 9g of A#5 with the 230HB & it gives complete lockback & cycles fine. It seems someone should be interested in a setup like this

Found this one & had to try it out. 14g A#7 with a 200g XTP. Do you guys realy fire this kind of stuff in a blowback
WOW. Very little reidue left also. I need to get some loaded up & get some #s on it. Very nice load!!!

Excuse me for being a noob, but are there working 9mm versions around or is the 9mm round to "wussy" for a gas system?

Ron, in your testing, what is the shortest, reliable length you believe you could make work for me in a pistol combo? I can provide a BM A2 upper receiver if you can do the rest of the upper and help me with what I need to get my pistol lower working....
I'll send an email in a couple hours. Congrats!! |

Great work, Ron! Marty, I set the 16" brl up that way! The 10.5" brl I set up to run just 45acp & it runs with "stock components" Look back at the post. Its ok, it happens to all of us. |

After I finish building one I need to build a nother 10" brl & start cuting an 1" off at a time & see when the system fails. It wont happen tomorrow but not much longer. I have more hunts comming up & I am sorry but nothing gets between me & my hog hunting! Well, except for the occasional oak tree

I really want to check out your work! I've got a DI 45 ACP in the works on the bench right now. Just had my buddy finish up the mods on the upper and lower to use Thompson MG mags. I've got a few posts in the 45 ACP thread about it. As soon as I am able to get my FFL (type 1 and type 7 mfg) I'm gonna see about getting an M16 FA lower, and see if I can make it run. Then the suppressor is next.... Just got my Smithy Granite 1340 lathe/mill/drill in yesterday and I'm ready to put it to some use. Congratulations on the DI upper––-I always knew it could be done, just didn't know if anyone else'd put the time and effort into it.

How far up the barrel did you drill the gas port? How Big is the port? I have my ideas, but want to see if you'll confirm them. I hate math, but I did some calculations concerning the ratio of how much barrel you need past the gas port. Anyway, I'm still cross-eyed from that one. Again, CONGRATULATIONS!

That's Ron's secret and he is guarding it well, rightfully so... I have a pretty good feeling where and how big, having one laying here that was borderline... may have to take it out again and test it with factory ammo to see if it will work. |

I understand, I'm willing to share my figures with him on a private basis myself, just looking for the confirmation that my figures will "hold water". I'm a gunsmith and I know trade secrets are a premium for us, but with a project like this, two (or more) heads are better than one. How long has Oly been the only game in town!? I wanna put them back down a notch. I can't produce a thousand of these at a time (nor do I want to), but I (we) have been told for so long that DI in 45 won't work that I just want to see a bunch of boys eat some crow.

Well, we put some lead down range today! All I can say is it works
Only issues was with the WWB 45ACP 230HB. That stuff is weak & dirty. The Fed & PMC we ran was flawless but we had extraction issues with the WWB. I think the powder they use is more akin to "chacoal" then powder. I dont know if the video worked or not. We had issues with the camera but we figure if the tape dosent work we will head back out tues & do it again. I have to confess that it does seem like a good idea to use a light buffer. Things were a little more robust with a no weight buffer but considering the recoil impulse kept me looking to see if it was running was interesting. She ran with stock components but I like the little extra umph I got from the lighter buffer. For somthing that was not suposed to work, I cant complain!
