Very cool T. Thank you. I'm thinking that a bullet in the bore where I plan to drill will help with burrs better than a wood dowel. Was also planning on reaming the ported area of barrel with another bullet and lapping compound to clean up

A bullet or metal rod would be better than a wooden dowel ,but unless your holes end up on the lands, and not the grooves ,you will still have burrs ,which could prove difficult to remove from the grooves.
Good luck with your project.

I'd be more concerned with mounting an optic over the dust cover, which is not known to hold zero very well. Have you done anything to tighten up fit and reduce the chance of the cover shifting? What good is a quick follow up shot if it's not on target.
Hey BB
Purchased a ncstar see thru dust cover with tri rail. Once fitted, I took it out and found the cheek weld WAY to high. Bought a side mount, again way too high as you have to leave room to remove bolt and dustcover. Disassembled the ncstar cover, cut off the steel square holding the tri-rail and then cut away the the 2 sides of the tri-rail. Found the centre line of the dustcover, taped the remaining pic rail to the top,and scribed the 2 screw holes.
Drilled out the 2 holes and threaded them with the screws it came with. Good Luck.. the screws were a perfect fit lenght wise and required no trimming as they weren't a hazard to the bolt. I then applied a fair bead of high temp automotive silicone to the underside of the pic rail and screwed it tight with a dose of red loctite on the retaining screws.
The ncstar d.c has 4 side flanges with scew and nut assemblies for tightening against the receiver. I scribed the 4 screw locations and removed a bit of metal, so the side screws could embed. I then ground down the protuberance o side screw and spot welded the nut and bolt together. Each one has it's assigned flange. I'm also using the polymer bolt and spring buffers that are available to help with vibration.
So far 300 rounds of surplus down the pipe and scope and mount are a happy solid unit. I have been slinging the rifle around by the short scope I have installed and it is in a really comfortable carry position just like a handle. I'm running a ncstar short 4x30re scope and it is good enough for my 200 yard requirements.I am grouping 2 1/2- 3" with no loss of zero after pull apart and cleaning. It hits what I am trying to hit or gets very close. Not the rifles fault, mine alone. I reload with strippers and am getting quite adept at it.
Next, I have a idea for eliminating barrel whip, or at least minimizing that condition. The goal is to build a $200 parts all-in1" moa, bubba beauty.
We'll see.
