Hey team
Am getting some surface rust appearing in the bolt lug channels and recesses and I'm guessing the chamber itself as well.
Was wondering what others are doing to clean this area of the rifle? I haven't been using a bore guide for cleaning the the barrel and I wonder if it's a result of residual boretech eliminator?? Google search comes up with a Tipton kit for this exact job but the International shipping kills it. It's a Sako A7 7mm08 if that matters.
Cheers
well you cant just assume either that your chamber has surface rust
to clean the raceways and stuff i use a loop end jag with a big patch and some oil on it and rub it all up in that. You could probably have a look down the chamber with a torch or something, but you can buy white swabs which i think are for shotguns but work well for swabbing the chamber.
and um... dont use steel wool on a stainless steel rifle.
Don't leave boretech in the chamber and barrel. It leaves a red residue. I always flush it out with meths.
I only leave Hoppes or Battisol as a oil layer in the barrel/chamber.
Try Eezox

Cheers for the tips, have got it pretty clean but not perfect.
Use a chamber brush...

Get the crap out, then make sure you flush all the solvents etc. Lightly oil, and use a bore guide for future cleaning.
You can buy the Tipton chamber and lug cleaning kit here in NZ. I bought one from Reloaders Supplies a couple of years ago, who look like they may be out of stock at the moment. Not as nicely made as the aluminium Jones Custom Products set I owned many years ago but does the same job. Workshop Innovation has them in stock.
From what I've seen, most shooters don't seem to clean the bolt lug recesses and re-grease them. The Tipton set makes the job easy to do. You'll also need to use a light smear of some good quality grease for the bolt lugs. Talk to Julian at Workshop Innovation or the boys at Reloaders Supplies.

Yes i finally come across this yesterday. I had already placed an order with Midway USA using You Post for the same kit and a bore guide but now after searching the forum it seems You Post may let me down on this. Time will tell.
You've been a long time out of the game if you think machining is done with carbon HSS much anymore.Quote:

so... this topic is relevant enough for me to post here. My AR15 is having some ... odd issues. I tried taking it out tonight only to find the bcg became jammed at about 90% of the way closed. Had to leverage it open with the upper taken off. Seemed weird so I took it home and had a fiddle round and couldn't see any obvious issues. I took the bcg right out and tried putting a bullet into the chamber to see if the problem was there and behold... the bullet becomes jammed in the chamber when it's about 50% of the way in. The barrel has had ~20 rounds through it and isn't particularly dirty... it's like the bullets have grown or the barrel has shrunk! Any ideas? This just seems weird. Happens across two different brands of ammo both of which have worked fine in the past. Nothing has changed on the gun since I last fired it... has just been in the safe
This should help the situation.

So to confirm, gun worked fine previously, but only recently has the issue?Quote:

Anyway yep, last time I used it was about 1/1.5 months ago and I put a couple of mags through it with zero trouble. So far as I can tell the bore/chamber is clean but I'm wondering if there might be some sort of build up in there that I can't see? Seems weird... the tolerances must be extremely tight for such a small build up to cause bullets to become completely jammed in the chamber.
What ammo brands?
Is it a .223 Rem or 5.56x45 chamber?
I'm assuming its factory ammo and .223, rather than 5.56mm milsurp.
it's 300BLK. Ammo brand is Hornady... same problem when I tried some American eagle which had also previously worked fine
Ahhh... okay.
What make barrel?
I would try to colour a case with a vivid and try to chamber to see where it is causing the issue.
I suspect either the chamber is not to modern 300 BLK specs (I recall there were differences in earlier 300 specs), so the headspace (shoulder), case neck thickness or even the projectile is getting driven into the rifling early that is causing the problem.
Either way, it sounds like a trip to a gunsmith to check.
barrel is aero. I'll give it a good clean out tonight and see if that fixes it otherwise ill send it off
Did you get it from NZRAC? As John should be good to deal with if you are having issues.
nah bought it off here, was unused at the time. Not sure how old it was but I think it's fairly new.
After a good dose of strong solvents it seems to be closing up again... hopefully it's fixed. Out of curiosity, how tight in a chamber should a bullet actually be? I've never bothered to actually test it but always imagined that if inverted the bullet would slide out under gravity... seems like it's actually quite a tight fit in there?
There is a bit of a squeeze so the projectile bites into the rifling.
I doesn't sound right to me.Quote:

I suggest a trip to the gunsmith.

Took it out for a spin tonight and cycled like a dream.... guess it just had a fine layer of gunk messing with it. Weird but seems fine now
