Jim Monica's Ultimate QB57!

Here's the absolute ultimate QB57 up-grade with nickel-plated barrel, gold-plated trigger and more! It's a real labor of love. Just look at the photos!!!!

This QB57 is the project of Jim Monica, who writes:

"I'm finished with my first project gun for the most part. It's a QB57 that I got from Archer. There are still things that I want to do to it, but that won't change the appearance of it that much so I decided to take the plunge and send you a few pics. This was my first project of this type. I was really using it as practice before I begin on the QB78 Deluxe that I got from you guys. I'm glad I waited too because I learned a lot working on this one.

Among the things still to do, I'm working on gathering the parts and pieces I need to install a laser, but I want to embed it into the front stock of the QB57 so all you see is a small hole in the front. I've worked out how I'm going to allow for adjusting it and switching it on/off, changing batteries, etc. I just need to put my plan into action and hope it works.

Here are the modifications I've made to date:

-Nickel/Cobalt plated and polished Barrel, receiver and internals. (Except the inside of the barrel!).

-Polished any metal to metal contacts inside the gun for smoother action.

-Stripped and re-finished the front and rear stocks using stain and lacquer to seal.

-Gold Plated trigger (14k - 24k was just a little too expensive!).

-Installed QF2 kit (From Archer) along with all seals and main spring.

-Filed down ends of main spring flat and installed Thrust washers for much smoother cocking action.

-Installed New hand grip. (Hogue Rubber Grip AK-47/AK-74 Rubber Grip with Finger Grooves. It's not the most comfortable grip, so I'm currently making a new one from wood to replace it with. The rubber one does seem to absorb some of the impact from the spring upon firing).

-Created, plated and polished trigger guard (I hate it and I'm working on a new one of these. I rushed the current one as I was running out of time)." Comment from Stephen Archer - well, it looks very good to me!

-Replaced all screws and nut(s) with polished stainless steel hardware.

-Installed Red/Green Dot sight.

-Threaded Barrel and Nickel/Cobalt Plated and tapped muzzle brake for screw-on attachment to barrel. I'm working on installing a set screw for extra hold. (Muzzle Brake is the one Archer sells for the QB78 Deluxe BTW!).

There are a few other small things but nothing too important."

Jim, thanks for sharing your project with us. It's beautiful. I can't wait to see what you're going to do to the QB78 Deluxe!
