Installing a LW 4.5mm barrel on RAW BM500

[aluisioalb]

Hi.
I need help to make the air passage hole in the barrel of a RAW BM500.
I bought a LW 4.5 barrel and to install it on RAW is necessary to make the hole in the barrel perpendicular to the air pass. The problem is that once made the hole, is burr on the inside of the barrel. Analyzing the pellet is possible to see the deformations caused by burrs and this is affecting the accuracy of the shot.
I need help-find a tool to remove these burrs caused by the hole.
Thank´s for your help.
Best Regards
Aluísio

A round file , riffler file, ...... Just to give you some idea of the tool you could use:

A decent gunsmithing catalog place or hardware should have them. Then polish no matter what eh?

Keep us posted,, Poly LW?

I use one like the 9th bit from the left in the below set. Put bit thru hole and then hold against side of hole while pulling with slight pressure. This will take the burr right off.

I got mine at Harbor Freight, but I'm thinkin you might not be in the USA? I would think any of the on line retailers like aliexpress or Amazon (if they deliver to where you are).

Just do a search for "Dremel Diamond Bit"
