So picked up my m305 from the post office today (I'd like to thank Al Simmon's gun shop for the speedy service) and as I type this, the gun has been separated into the major groups to clean all that preservative oil. I've been reading as much as I can on the net for the last few weeks and I've just got a few questions:

The indexing seems off, the gas assembly/barrel seems to be turned clockwise if looking at it from the front end, does this make the gun unsafe to fire at all?

Also, I assume the front sight is adjusted by backing off the set screw and just sliding it left/right?

As far as the bolt goes, I just sprayed carb cleaner down the firing pin hole to clean it out. Will that suffice? I don't have any special tools to dismantle it. I'm going to check the bolt lugs once the gun is back together again and report on what I find there.
 
your barrel appears to be slightly over-indexed(too tight).
it needs to be slacked off a bit.there is a setscrew on the oprod side of the receiver that needs to be removed.
then using a barrel vice/action wrench you reindex the barrel.it can be done @ home if you're handy with tools and willing to
get down and dirty.minimum tools required:
screwdriver slotted that perfectly fits that setscrew.apply lots of penetration oil and wait a day or 2.
try to unscrew setscrew.if it strips you need to use an "easy-out"(drill out center of screw,smack in easyout,remove)--careful drilling out center--
purchase 13/4 open ended wrench.
you need a strong and well secured vice--make up some hardwood blocks to secure barrel.
apply duct tape to receiver and barrel to avoid marrind.

easier way:
contact "hungry".he'll help i'm sure

Hmm that's what I suspected. In the stickied inspection FAQ thread it says:

2.) The barrel may be incorrectly indexed to the receiver . If the front sight leans to the left, and the rear sight is adjusted to the right to compensate, then the barrel has been over-tightened. To correct this, the barrel must be removed, and the barrel shoulder must be rolled back to remove the metal distorted by this over-tightening. Since proper alignment, torque, and fit of the barrel shoulder to the receiver is critical to accuracy, this is not a trivial fix.
Click to expand...

I'm cool with attempting to reindex myself, but the part about damage done from the over indexing is concerning. I don't have any experience with precision metal work. Is there a way to determine if the over indexing requires that extra work?


Edit: I've also sent a message off to hungry

the over tightening is not huge IMHO.
justs needs to be backed off a tad.i don't think there is any shoulder damage--but i'm not an expert.
just someone who's rebuilt a couple of m305's and garands...
 
Well it's more experience than I've got :)

The gas lock on this thing is super tight...just about the complete opposite of what I've heard about these guns :confused:
 
I see you are from Ontario , you could also contact Ellwood Epps for an estimate as they can fix that .
If the barrel was under indexed it is an easier fix (with the proper barrel vice).
 
Some pics of when Hungry showed me how to index my barrel at one of his clinics.
In my case this rifle was under indexed and I had to pull down on the wrench with ALOT of force to move it.

You attach indicators to the front sight base and at the rear of the receiver and move the receiver into the correct position (when the indicators line up with each other).

I've actually been waiting for confirmation on his Ottawa clinic. Didn't get a rifle in time for the Burlington shop. I sent him a message earlier though for another opinion on it. I won't be firing it for at least a couple more weeks anyway.
 
And I will be organizing another at CFB Petawawa this fall , it will be a 2 day clinic again like last year with shooting on a 600 yard range :dancingbanana::dancingbanana:
 
...and so begins my infection with the m305 bug. Might be a little while before I'm ready to fire anything close to 600 yards though :redface:
 
PM inbound. We are gonna sort this out. Easy Peasy.... just cost ya the return shipping. No worries, mate!

Just returned from the gym and brunch with a local CGNutter from 2VP on a "course" in PET....

I got yer backs! ;)

Cheers,
barney
 
Another example of why the Main battle rifle section on here is the best....Well done Barney !!
And you should try and make it to the Petawawa clinic....with Hungry,s help you will be getting hits on target at 600 yards .
Just get rid of the Norinco rear sights or put a good scope mount and scope on it.

Can't say I'm not impressed with this site for sure!

I'll have to see to it. I am interested in long range shooting. I'm planing on doing the standard accurizing stuff to it like unitizing and shimming, although the gas lock on this thing is super tight so I doubt I'll need the shims. Get myself a rail off of m14.ca and one day a boyd's stock whenever they're on sale and try out bedding the stock on my own. The possibilities for this platform seem endless :D
