So I ran into a small snag...
I trimmed off the stock pilot, and it came out great.
But... it also seems that my preliminary measurements were off and the Atlas pilot will need some tweaking to fit.
The curves of both pilots match perfectly at the rail side, but at the body side, the curves don't exactly match.
Therefore, I'll have to cut the anticlimber flat to match the pilot. Hopefully there's enough material back there so I don't have to fill. Fingers crossed.
And yes, the Atlas pilot curves are correct.
Thanks!
