Hi guys,

I've recently purchased a new internally stock VSR-10.
I'm planning on doing all the DIY mods I can to squeeze out as much as I can from it and one mod I was considering was shaving down the bucking moud.
I was wondering if shaving it down would affect the performance of the hop up? I've heard somewhere that it helps!

Thanks, Milo.

Shaving down the arm nub or the bucking mound?

bucking mound! Sorry, my mistake, I was tired and about to go to bed when I wrote this. I'll edit it.

Shaving down the mound would give you whatever shape mound the nub is when you turn up the hop. This is where an SCS nub is useful or an H nub. I wouldn't do it with the stock toothed nub because that would give you a weird mound shape. I personally wouldn't shave it down either way because I'm crap when it comes to that (found out how bad I was when I installed my r-hop and had to shave the mound). It takes a bit of skill to get it as smooth as you need to get it.

If you do it, get another bucking so you don't screw up your current one. Also remember the smaller the mound the more hopup you will have to apply to get the right backspin.

It'll help if your planning on fitting a new nub, like an SCS or H nub, into the hop arm.

Other than that, if you leave your arm stock, it will reduce the amount of hop pressure you will be able to apply, to the point of, even mid weight ammo will be hard to get to fly straight :doh:

Doing a TDC mod will help apply as much hop you need to correct that issue. Also no right hooking too.

I am doing the TDC adjuster and shimming the hop up chamber too. I guess that's all I'll do to the stock hop up. Thanks!
