So I have seen a lot of people asking about this before.
And I wanted to try a tight bore barrel and a short barrel on the VSR, so I figured out I might as well use the stock barrel the VSR came with.
now the specs on the barrel I got was. (Turns out they have a tendency to change the barrel on the different batches so yours might be different).
Bridged hop-up window.
So to make this work with the maple leaf rubber I need to remove the bridge.
And for this all you need is a fine grit flat file like this.
And then all you need is time. the barrel I got was made out of brass so it wasn’t to hard to file down. but it still took me some time. (Around 1 hour.)
So my tip to you is Netflix or music. I spent the time listening to a podcast.
Now after about 15 min I got this far. And at this point you just need to keep working untill you have about 1mm left.
You don’t need to pay too much attention to it until you have about 1 mm left. At this point you need to pay attention to make sure you get it straight.
The part in the middle that you can see will not be filled of so you just need to break it off.
When you get that off its time to make sure you don’t have any sharp edges touching the mound on the bucking. So grab the file again and file down the edges a bit.
You don’t have to worry about the part that was cut by the factory as they tend to be smoothed out, it’s just the part where the bridge was you need to worry about.
And that’s it. Now you can use the maple leaft monster and autobot buckings.
And you have something that looks as close to a stock open window barrel.
