M6 Light Primer Strikes


Recommended Posts

HI RRO,

 

Mine digests anything I feed it from 230 Ball to 200 LSWC. Nothing seems to stop it. I imagine you are running M6 magazines? Factory barrel & chamber? Not much else left other than the recoil spring.

 

Might try a de-primed case to see if it snaps easily under the extractor. If there is an overly aggressive extractor spring it might keep the round from aligning with the breach face as the bolt goes to battery.

 

Can't think of much else.

As far as I know everything looks original but who knows what has been done to it over the years. Barrel is finned. I have (1) one M6 mag, lol. Not much to go on to check in the way of magazines. I would like to figure out how to convert a Thompson mag. I wonder if that can be done without machining?

 

I removed the extractor and the spring was rusted and very stiff. Perhaps this may be part of the problem. I'm thinking there is enough blow back that the round may extract without the extractor?

No, the gun will be very unreliable without the extractor! What are you thinking?!? As I noted to you in an e-mail, the extractor slot needs to be fully cleaned of rust and debris, and the rusted spring replaced with a new spring. Of course, the extractor slot needs to be cleaned of rust and any accumulations that might keep the extractor from functioning properly. Check the lip of the extractor and see if it is broken or heavily rounded and needs replacement. A frozen or tight extractor can prevent rounds from properly entering the boltface recess resulting in light strikes.

Replacement extractors are available if needed.

FWIW

if you need spare parts i know someone who has some...he only gives parts that are needed...not to collect...if your gun wont run he may be able to provide the parts for you....

 

none of it matters...you shouldnt be fixing the gun....Ruben sold you the gun and he is not a cheap dealer...he charges a premium on his guns for his great service....ship it back..let his repair guy replace the spring and extractor...shouldnt come out of your pocket....luckily the springs are available....you missed the mags by 15 days...you could have bought as many as you wanted...

that is awesome....and as it should be...congrats

 

how many rounds do you have through it so far?

 

i just refinished the wood on mine and learned about dissembling the lower...mine should be out of jail in 3-4 months

huggytree, I need a sight elevation piece if your friend that has spares has one.

 

timkel, here is the assessment from Bob Naess who fixed it:

 

The barrel appears to be a replacement to me, but it might be original. The gun has an early serial number, 344, and it is possible that early guns had composite barrels in the fashion in which yours was done. The breech ring, which is numbered to the gun, is a separate part, bored out, threaded and a barrel threaded into the ring and cosspinned. Bore is excellent.
All the M6s, both police and commercial guns, that I have worked on have been higher serial numbers and all have had numbered, one piece barrels, so this one is unique in my experience.
The bolt in your gun is a composite also. The body of the bolt is one piece and the smaller OD section with the firing pin, extractor and ejector groove is a second piece. You might recall what it looks like. The body is half-section for part of the way and the second piece is inserted into a centered hole about in the middle of the body and crosspinned with the smaller OD part extending forward.
The bolt impacts the breech face. Since the headspace was too long, I chucked up the bolt to skim the part of the bolt that impacts the breech face. Unfortunately, the smaller OD part is no longer perfectly concentric with the bolt body interfering with working the face of the bolt that impacts the breech face. I removed the cross pin holding the smaller OD section in the body, but could not remove the smaller OD part. I was able to skim some metal but the eccentric smaller OD section interfered and not enough was removed to close up the headspace.
I removed the barrel, skimmed the breech face and tested the headspace several times to allow the small OD section of the bolt to close up the headspace sufficiently to correct it.
The extractor was pretty well worn and would not reliably extract so it has been replaced.
On removal of the barrel, I also disassembled the foregrip from the barrel. The foregrip was cracked through along the woodgrain at the thinner crossection. The mounting bar for the grip is screwed into a channel on the top of the grip which was holding it together. I glued the grip back together with an epoxy glue. Other police M6s that I've had also had cracked grips due to the way the grips are made with the diagonal woodgrain. The angle of the grain makes the grip vulnerable to cracking when the grip is pressed forward or backward in use.
The elevator for the rear sight is missing, which you might already know about. I don't know where to find one of these, but there are sight specialists who will have the parts since it is a standard KING sporting sight from that era.
I have tested the gun with several full mags and it functions as it should. Mag works fine.

PM sent...maybe you will get lucky and he will have what you want...he reads this forum, so he knows your situation already

 

 

what composite is your barrel and bolt made from? what is meant by that?

 

the finish on your gun is so even im surprised it could have a barrel replacement

Very detailed report. It adds a lot to the knowledge base of the Ingram M6. You made a good choice in sending it to Bob Naess.

I believe he's referring to composite as in assembled from multiple pieces as opposed to a single piece.

Hi All,

 

I have access to several earlier M6 examples. I'll look them over carefully when my eyes are better (in the morning). I'm pretty sure the barrels are of 1 piece. I don't recall seeing the S/N at the base of the barrel but I don't spend as much time as I should with the Ingrams.

 

Just guessing as I've not seen the one with the composite barrel; could the barrel have been damaged and to repair it, a new blank was machined and attached it to the factory "stub" made by boring the breach end of the factory barrel?

 

Only a guess. I've been surprised at the variations in the Police Models that I've seen to date. Could just as easily been another factory variation that I'm not aware of.

 

Still learning,
