To be honest I cannot even recall what size we used as it has been years and my machinist did the work.
That being said, as guys do the conversion with dremel tools I suspect any reasonable size bit should work. A quarter inch sounds reasonable.
Can't find it on your website
I have to ask if I install the AR adapter can I use the regular mags, not factory but the tapco ones??
I was just looking at my SKS thinking about that lol
Is it wrong to love the clack clack bang, but wanna run from a click tick lol
I lost the adapter for a spell, and tried to convert it, lost the original stock also haha, I put things down and they walk, got the stock gonna inlet it this weekend, and the adapter I have it now, but ones you mill it out the rounds won't angle I to the chamber
