M14 Bolt Lug Wear Points - Lapping req'd? *Pictures*

My first impression is to leave it be but make certain that the roller is lubed. Might just be me but it looks dry and the external radius is a bit coursened by the finish. how freely does it roll?

If you're still concerned, I'd certainly get 3-5 rounds through her and reinspect without being too critical.

Cool enough. Lube that rascal and fire it off a bit. I'd be surprised if you needed to address it though that does not mean it's necessarily a bad idea later.

Something to keep in mind are the variations of the working of the action by hand as opposed to actually firing it. Let the gun tell you what it wants after a couple-three magazines.

Nice. That and an unbinding release will get you going. Just to set your mind at further ease. When you're in a safe shooting environment, hand cycle a round through it and take a look at the case and not bolt lock-up when in battery.

I'm sure there's nothing to worry about but something caught your interest already so making a point of looking may pay dividends later.

In any case, these are tough and generally very reliable rifles.

Leave it alone. Especially if you don't know what the headspace is. The chinese ones run pretty long to begin with.

Use .mil cartridges which are designed for more generous chamber lengths and you should be OK.

Those ersatz rifles are turds. Get a Springfield Armory M1A if you want to shoot an M14 clone. A Garand M1 is also a good rifle.

I saw a Polytech that had stretched enough to create excess headspace. That was enough to convince me of the quality. No thanks.

In my opinion the USA issues/issued the best.They just needed a bit of slicking up and would be almost 100% reliable with a proper diet.In fact, after our slick job, never heard or saw one FTF or FTF or, FTE. But the "porting and polishing" should be an only if needed affair.You want the gun to "wear in" itself as best as it can.Lug wear and messing with that area can be tricky business.If your gun hasn't been fired much, I would suggest shooting it quite a bit before making any adjustments.
