r/Mk12Mod0

The Mod Holland is my favorite and I am not biased at all🙂‍↔️

Went from this setup to this setup. Mock12 to mk12

(Oddly enough the swan rail on top seems to slightly cant to the right like ever so slightly. Not sure why)

Got an odd build I’m doing, not an mk12 clone but I don’t think there’s a better sub when it comes to knowledge on the pri handguard.

I want to add a carbine length top rail to my 14” tube to add some rigidity and anti rotation without adding as much weight as doing the whole 14” top rail.
Sadly they don’t make a recce rail that works with the 14” hand guard.

I’ll have to drill some more holes in the top of the rail to attach the front of the rail as it won’t line up with the existing slots. What drill bit do you recommend? I saw somewhere that tile style carbide bits like the 3rd pic work best drilling into carbon fiber. Is that what you would suggest? Or would hard metal bits like in the 4th pic work fine?

Thank you for any input you have!
