Hey guys. really need some advice from someone smarter than me, people who know barrels, head clearance, 5.56 and maybe Type 97, so I thought I'd post here asking for opinions, advice and maybe help.
I don't actually know if I have a serious problem or I'm an idiot worrying over a non-issue.
Anyway, got a good deal on a Gen 2, all seemed well, until noticed the right side of the chamber had a chamfer in it that I don't think should be there. Decided to see how much it affected the chamber support, so I removed the striker, bolt and bolt carrier and inserted a dismantled casing (no powder or bullet in it) to check how much case was exposed.
The thing is, I don't know if I need to be worried about it or if this is an acceptable tolerance for 5.56 or for this rifle. The length of the visible part I am concerned about, from chamber to the first ridge where case body ends, is about 0.060"-0.065" (I believe the visible part is roughly half that on the other side, as the chamfer there seems smaller, but I'm guesstimating). I will try to include a picture for a better visual of what I am talking about. Fist shot regular, second a closeup that probably exaggerates the issue just because it's zoomed in so much, and last is me trying to scratch the casing for a rough visual of the amount what I can see on the right side.
If someone more knowledgeable about .223/5.56 round and the T97 platform can let me know if this is within tolerances for cartridge/platform or if I shouldn't shoot it and take it straight to a gunsmith, please let me know, I would be very appreciative, as I'm not sure if I should worry or not at this point. Thank you.
