Well it's about time I started this thread. Been working on this project for a while, but now there's actually something to show for it.

This is a complete re-think of the VSR, and airsoft sniper rifles in general, while still maintaining backwards compatibility with core VSR parts. I've basically redesigned everything from tip to butt (;)). Only standard parts left are the cylinder, bucking, inner barrel, and trigger (sort of). Will start with just showing some pics as I don't have all the hardware in yet to fully put things together. Not every part is shown here, just some of the cooler stuff for now.

Design, certainly, but (I think?) the parts were made by Mancraft.
I have a machine shop that I work with. Not Mancraft, and as far as I know they don’t do anything else airsoft related.

I think you might be thinking of the stock parts. The regulator I’m using is one that Mancraft makes.

So far so good. All those wacky ideas I had have worked out up to this point. I need to do some massaging in one area of the receiver, but otherwise it's fully functional! Was getting just 0.01J deviation in energy output with a thrown together cylinder. Really curious how it's going to do with HPA now.

Cool pic. Also, the rest of the stock parts should be here soon so I can maybe assemble the complete thing in a little bit. That being said, I'm reworking a bunch of the stock for strength so a lot of it will change anyway.

Essentially, works exactly like the buffer tube on an AR. That grey piece is just a big jam nut that pulls the barrel threads tight, and the ring of three screws just provide anti-rotation (they fit through holes in the outer barrel and don't actually press on the threads). Technically this works with all standard outer barrels too. So, if you wanted you could have whatever profile or look, but with the rigidity of a one-piece setup. That jam nut is made from 440 stainless steel, heat treated, and then black oxided. Probably overkill, but whatever.

The outer barrel is still threaded into the receiver, so you’d set the distance just like any other standard VSR. Although I have a cutout in my outer barrel that lets you see how close the front of the cylinder is from the hop up chamber. Also you can move my hop up chamber forward and back in smaller increments to take up any extra space that couldn’t be done with the outer barrel.

Once the anti rotation screws are in the outer barrel, it really can’t turn at all. But you can always match the flat on the top of the TDC to the flat of the rail for perfect alignment.

There's tons of bull-barrels on real rifles. And especially on shorter barrel guns, I prefer the look. The MLC stock is essentially perfect for a spring gun too. It's so comfy and sturdy and I think it looks awesome.

Also, I'm way past replicating real rifles. I've got plenty of those and don't need any more. This is all about squeezing every last bit out of an airsoft-only rifle. If that means leaving behind features that are on real guns, so be it. Replication doesn't make much sense once the replica is multiple-times more expensive than the real thing.

Going to take some time to highlight the barrel system I designed. Out of all the new stuff, this is probably the bit that will make the largest improvements to accuracy and consistency. To start, this is completely backwards compatible with standard VSR receivers, but there is obviously a benefit to using my receiver design. Essentially, the locking nut is used with my receiver, but not with a standard receiver. On a standard receiver, it would attach just like any other outer barrel.

What I did here was completely isolate the hopup chamber and mag block from the outer barrel and stock. Normally, you'd clamp the hop up chamber between the mag block and the outer barrel and then to the stock, but in doing so you almost always pull it off-center within the outer barrel (because the fit between the chamber and outer barrel always has some clearance). And when you pull it off center your nozzle is never going to line up correctly. You can normally try to correct this by wrapping your chamber in tape or using o-rings to help center it, but the screws will pretty much always be stronger and still pull it off center.

So to fix this, my chamber, mag block, and TDC are not being clamped across the outer barrel in any way. Instead, it is screwed directly into an intermediate cap which then screws into the outer barrel like your normal flash hider would. By using threads that are all facing the same direction, the hop up chamber naturally wants to sit directly in the center of the outer barrel. I then use a big spring to keep tension on those threads so that the chamber can't wobble with the looseness of the threads. Lastly, the TDC and mag block are directly connected to the chamber so that there is still no way for it to get pulled off-center. Perfect alignment, every time.

The design of the chamber itself isn't anything radical. Very similar to an AA design, except with the provisions for the TDC and mag block. Uses a similar arm design to my normal AA arm with the same primary geometries. Mag block is entirely self-contained, and uses Cyma guts currently. Didn't plan to fix all the issues with mag catches, but this does that too.

Lastly, the hop up chamber, intermediate cap, and flash hider all have inner barrel centering/locking provisions. The chamber and intermediate cap both use the same triple-sided brass locking collar, and the flash hider uses some x-rings to center the barrel. No need for any other barrel stabilizers.

TDC wheel is clicky too, obviously.


*the hop up arm in the pics is just a placeholder for now. Haven't made the new ones yet.
