Its finally time... I leave in the am to go Michigan to spend the week with Brent at Extreme Big bores. We will be working on a few upgrades to my gun.... New breech, possible slide magazine, carbon fiber sleeve, muzzle brake and I have my master stock with me to meet with his stock guy to hopefully CNC a few stocks..... and a few more ideas that I hope we have time to build.... I will be posting pics and progress every day from Brents shop. Stay tunned, this should be alot of fun!!!!!!

I am jealous Mike. I've been there. Great guys and they do great work. Particularly interested in the carbon fiber sleave. Why not also go to a titanium air tube and cut a couple of pounds? Brent has done these before.

We got started today...... We cut the barrel off and re-threaded for the new muzzlebrake. We also installed the carbon fiber sleeve and got the breech roughed in... Had a few setbacks but we prevailed!!!! Brent is one talented man. I am very pleased with the results so far..

Brent had to put together some guns today so I Finished my master and we got the breech close to done. we will finish the breech and the magazine tomorrow, then off to Brents stock guy thursday. I may still put vent slots in the forearm of the stock.... Not sure yet..... Here are a few more pics......

Brent Got the breech and bolt done today..... I mounted the accessory rails and mounted the harris bipod reciever on the bottom of the forearm. Started working on manual indexing 3 shot slide magazine. Should finish that tomorrow.. The gun is really shaping up and I am super excited. At a later date I may fit it with a rotary mag but for now I am going with a three shot slide mag that I designed.

Geeeez Mike,

"Brent had to put together some guns today so I Finished my master" . . . boy, I hope one of those guns Brent is finishing is mine . . . you must be the reason my Extreme is taking so long to get built . . . grumble, grumble

Ron- the barrel is a tj liner with 1/32 twist and a custom carbon fiber sleeve from clearwater composites with a 1/8 wall thickness. The muzzelbrake I ordered from Accuracy Systems in Byers Colorado... They are super guys and highly recomend them based on my experience. The breech is made of steel... Brent felt it would be safer than aluminum due to the high pressures his gun uses. The stock is a master That I created. The picatinny is Magpul and the bipod reciever and bipod is made by harris bipods. I designed the RVA thanks to Bob Stern.... Great Idea Bob! Thanks. The bolt is Brents design And is altererd to accomodate the slide magazine.

Fred- we are picking up your stock today and all the other parts of your gun are made. You won't have long now!

Thanks for the replies guys! gotta get to work.....

Interesting project I admire the talent and skill required to bring that type of project to completion. I can't wait to see the finished rifle.

I'll definitely be watching

Interested to see how the stick mag works?

Rizen 1 · « **Reply #19 on:** May 07, 2015, 07:17:36 PM »

We worked on the slide mag today.. This is a manual 3 shot mag. My goal for this gun is to tune for 3 full power shots for hunting. The interesting thing about this mag is that Instead of using spring plungers and dentents to stop the mag slide at each bullet hole, I used magnets perfectly spaced to accomplish the stopping points. I am so picky about scope height and fit and feel of a gun that Brent and I have this gun squashed down as low as we could go...... You literally can not make this gun even 1/16" lower.... so I had tested my theory a few weeks ago and it worked with the magnets.... But you have to be spot on!... So.... How does the mag work? FLAWLESSLY! When you push it with your finger the magnets release and go to the next set of magnets and lock down... Even though I had tested this theory I was In awe of how well it works.... Goes to show ya... If you have an idea and people tell you you are crazy.... You just might be crazy... But it doesn't mean your idea won't work! LOL!!
