Understood. I searched online for other people finding this kind of tool too tight. Not hardly any complaints though, which I find strange. Not a single negative product review either saying that it would not fit. Has me thinking, I don't imagine any of these tools working well then in a BCM Upper, with its interference fit on the barrel extension.
That technique I thought of, clamping a spikey pick tool in the vice to use as a pilot, and spinning the lapper with my drill actually works extremely well. It gives me a free hand to apply Emory cloth to the lapper as it spins. I've made a little bit of progress, but it's not quite fitting smoothly yet. And I have to run out to the HW store to buy more Fine and Super-fine/Polishing grade cloth to continue the job.
