That answers everything. Appreciate it.No worries.
I removed the bolt handle, firing pin assembly, plunger ejector, and extractor. I sent the bolt body only. Honesty just bc it was easier to package; he didn’t need it disassembled. I did the plunger & extractor bc I’m picky and didn’t want to find plier marks on them when it got back (not saying it would, I’ve only heard good things about Kinport Peak, but I’ve dealt with many gunsmiths and if I can do something myself I will).
As far as magazines, I specifically tested this a couple hundred times with each version using three different dummy rounds that had the bullet seated to various lengths. @Juan_ID had posted that they worked fine which was actually my tipping point for going ahead with the build. I was concerned that the extractor could bind up on the case rim, and if closing the bolt slowly it’s very slightly more perceptible than a standard 308 version, but otherwise it’s as though it was made by Tikka from the factory. Works flawlessly. The M magazine does feel like it feeds a touch smoother than the S magazines though. But again I didn’t have any hangups running the bolt slow to fast & in-between.
I imagine theoretically that the bolt face modification could cause headspace issues, but I have all three gauges and it was right where it needed to be for the one barrel I’ve tried thus far.
Hope that helps! I have zero regrets, Tikka should offer this as a factory option. I’d buy two or three immediately.
