I built this in September of 2016 for EBR. I desided to post some of the picks I have for it.

Barrel was ordered in January of 2016. Took around 6 months to get. I then machined it to fit a pre 2013 spin loc condor frame. The old triggers are way better and with a super sear are fully adjustable.

Scope rails blanks were made by Tom. They were 1.25"x.850". I then had to put the center slot and ball mill to fit on the frame after cutting off the old rail. I used 4 10-32 allens to attach it to the nubs I left from the old rail.

Trigger guard is also .850" wide and was made from scratch. It covers the trigger group rail also.

In September of 2017 I made a monster shroud for it out of carbon fiber. Had to chuck up the barrel to and support the rear of the frame to turn threads on the OD of the frame.

Right now it is sitting on my bench apart. I sent it out for anodizing. Haven't had time to put it all back together.

This was September of 2017

So right now gun is setup at 3100 psi. Shoots a custom 165 gr bullet at 975 fps.

When I first built it it was set at 3400 psi and was shooting 995 fps. I did a little tweaking to get more out of it and lowered the pressure to get more shots. It gets around 16 shots within 10 fps.

So...what do you do for fun Doug?

Glad to see you posting this! Artistry in metal.

You should post some of the close-ups of the Picatinny rail n action modifications where it fits, same pics you sent me were fascinating, others would sure find it interesting too.

That regulator is so awesome, it's so 😎
Get ready for lots of pleading for you to start producing them.

Wow Doug, that’s a thing of beauty. Now I see the plenum arrangement , that makes more sense now that I see it . How much volume does that plenum have ?

Thanks everyone.

I couldn't find pics of making the scope rail for the 338.

When I built the 338 I built 3 new guns and converted my 308 to picatinny and large trigger guard. I built a new 257, 308 and 338. The new 308 has sense become a 375.

Here are the pics of when I did it for my Texan though. Same deal except there was room for 1 more screw.

Found the barrel pics.

First 2 steps are hard chromed. The hammer rides on the barrel with oil filled nylon 66. Stuff is hard. I found that the stainless is barrels are not as hard as the hammer forged chromoly TJ barrels.

Found a place that could hard chrome the wear areas. Asked me how much I wanted on. So I took the 2 machined pac nor barrels that I didnt care if they messed up. Came out perfect. Then I machined the .257 and 338 barrels and had them done.

Stuff is hard. I have 4 more barrels that need to be machined and chromed still. Some day when time permits.

Doug, your work never ceases to amaze me!! Beautiful guns!!

Beautiful work Doug.... You deserve every bit of success, the time you have put in developing the AirForce platform is amazing.... Very cool to see the finished plenum.... What was the final volume you decided on?....

Thanks Bob

The plenums are around 23 ci. I have made only 2 because of how hard they are to make. The only reason I have 2 is I couldn't finish the first one. I couldnt hold it to put in the reg hole. So I started over and had to do the reg hole step first. Then about a year later I found a way to finish the 1st one in the mill. I had some end millscustom ground.

I have a design that will work a lot better but it required to be done on CNC mill. Been trying to get it going for around 3 years but no luck.

Same setup works on my 50 and is making 740 fpe on 3100 psi.

I need to use water and get exact CC here some day.

As always a fantastic job!!! I noticed a texan style valve instead of one of your valves or is it a new mod?

rsterne · « **Reply #15 on:** August 02, 2019, 02:26:11 PM »

So that works out to about 377 cc, plenty big enough for 400 FPE, and will work to double that with about a 10% pressure increase.... Great design, too bad it's so hard to make....

I have a severe case of plenum envy!
