My beloved M305 is not feeding properly from any of my 5 or 20 mags. I would rather let a pro sort it out. Can someone suggest a good M305 mechanic in the Kamloops or BC area in general?

Please be more specific. It could be anything other than a mag problem.
 
Mystic Player and Skullboy are in BC (resident M14 pros). If you post a more detailed explaination of the problem you'll find it will save you a trip to a smith 90% of the time.
 
At what point is the rifle misfeeding - not picking up a rd? stovepiping? not going fully into battery? etc? etc?

For the most part, the feeding and in some cases, extraction is directly controlled by the mag feed lips and its location in the action.

The m305 has proven to be a dead reliable action. There is always a chance of a dud but I would look at your mags and what you are feeding it.

FWIW, the base of the rounds are - for whatever the cause - not sliding up into the bolt face. The result is the round hanging up in the chamber half-out at too sharp and angle. I pull back the action a half inch or so and the tension gets relieved and the round will chamber. I've cleaned and polished everything and i see no cause for the fault. Same ammo (Port 7.62) and same batch as I was using.

This is a completely stock rifle and it is a toy. Not heavily invested in it, but it has be flawless until now. I have had to surrender my testicles in order to admit that I just screw up trying to fix things like this on my own. I have more piles of parts left over from my fix-it projects than I care to admit.
 
From your explanation, I am guessing that the bolt stops on the case beyond the rim? ie rim is in the mag but bolt stops part way up the case after moving it forward so bullet has entered the chamber.

When you pull back on the bolt, the case pops up and the bolt can now pick it up. If so...

Open the rear of the feed lips so that case rises higher in the mag.

Follower spring may also be weak so not pushing case up against the force of the bolt. Dirt in the mag may be holding up the follower. Does it occur with every rd or just the last one?

Simple solution, swap another mag.

Yup, exactly.


Happens with every mag and happens with basically every round. My first assumption was the mag(s). I tried different mags and I tried reducing the number of rounds in the mags too. Mags are all clean.
 
don't want to butt in, but summerland isn't all that far from kamloops - maybe you guys should have a face to face some weekend or something?
 
Try this. Hold the rear of the mag up and let the bolt fly forward. Does it pick up the rds then? If so, the rear hold point which is the mag release, is bit too low. You can try swapping a new part in. See if Marstar has any parts or swap in another trigger group to test.

Or, you can put a small spot weld under the rear mag tab and file to fit lifting the rear of the mag up.

Also, you can open the mag lips as mentioned before and see if that helps.

Also, try a mag from a rifle that is know to function. Most Norinco mags are excellent but there are lots of US aftermarket that are crap or at least don't fit all that well.

Good luck...

or if you bought it from a reputable dealer - return it with a description of the problem for repairs, send the mags also.

A no BS warranty is your best friend... they have been known to do charity work on firearms they didn't sell, just because they can...

All quirks aside - how can you beat that?

Apparently, the position and type of the op rod and the slot in the reciever can have a major effect on your mags and feeding. Don't know if this is going to help or not, but it is an intereseting read. Especially about those expensive Springfield Armouries recievers;)
