Fitting usgi bolt in norinco

Just curious how extensive it is to fit a USGI bolt from fulton armory into a norinco ? thanks


From the M14 FAQ at the top of the forum..........;)

Bolt Replacement & Fitting.

This is for those who wish to swap in a USGI bolt.

NOTE: Use the proper Headspace Gauges to check headspacing throughout this procedure.

First, make sure it is a USGI bolt, and not a Springfield Inc. bolt.(A run of commercial S.A> bolts were recalled)

You might be lucky enough to not have to lap the bolt.Swap out the old bolt and install the new one without the op rod attached.Move the bolt back and forth in the reciever and see how it fits and locks up.If everything looks good, then put the rifle back together.Just to see the difference, replace the original bolt, and slide it back and forth, and see how it locks up.Odds are that the USGI bolt has a tighter fit.

Once the rifle is back together, cycle the action a few times to see if there is any binding,roughness, or sticking of the bolt.If there is, you will want to lap the lugs.When I did my bolt swap, if I let the op rod fly home, it took a good deal of effort to open the action.If this occurs, you will have to lap the bolt lugs.

To lap the bolt lugs, you will need 400 to 800 grit valve lapping compound(available at your local auto parts store).

You will also need a Full length sized case and a rod (or pin punch) that will fit into the extractor hole.

NOTE: The bolt MUST be stripped in order to properly lag the lugs!!!!

Remove the op rod, op rod guide & spring. Install the stripped bolt in the reciever .Dab a little of the valve grinding compound on the rear of the lugs that bear against the receiver locking cutouts.

JUST a little.Don't over do it with the compound.

Now place the sized empty case in the action and slide the bolt closed. The case will keep the bolt centered with the bore when lapping the lugs. Insert the rod/punch into the extractor hole and rotate the bolt open and closed. You just lift the lugs up & down.

Do this approximately 25 or so times. Stop and check frequently by cleaning off the lapping compound and working the bolt. The bolt should fully lock up without any binding or roughness. Repeat lapping as neccessary until the bolt opens and closes smoothly without any binding or sticking. You should be able to cycle the action easily.

If you reload, I would make up a few Dummy rounds and cycle them through the action via the magazine and see how it functions.If everything seems good, go shoot the sucker.


When I swapped bolts, I went from 1.642", to 1.628". Minimum SAAMI spec for a .308Win. Chamber is 1.630". Now my chamber is at two thou crush, which is exactly what my old TRW M14 was at. Now, if you reload, you will have to readjust your sizing die accordingly. Also, no more shooting cheap surplus ammo.You will now have a nice tight match chamber!!!

After you are all done, MAKE SURE YOU CLEAN OFF ALL TRACES OF THE VALVE LAPPING COMPOUND.


I don't know exactly where you are located in Ontario, but if you are close to Hungry, I'm sure he wouldn't mind giving you a hand. It's a bit of a long drive for me.

It is actually pretty easy to fit the bolt, and it feels good knowing that you did it yourself.

SKBY.

Thanks.. I had no problems getting one imported into Canada

By your buddy in the USA no doubt and not legally.

Question: Can you ship __________ to ____________ (Canada, France, Italy, Germany, US Military APO addresses, Japan, etc.)?

ANSWER: Fulton Armory is permitted (by the US Department of State) to ship to USA addresses only.
 
Walking usgi parts across the border is like russian roulette. Please understand that if either you or your american friend get caught, one of you WILL do time in a us federal institution. weigh the risks and consider carefully before risking everything for a $300 part.

I'd like to hear of the last time someone was actually sentenced to time for trying to import one M1A bolt.....really? I would think more of a fine and prohibition of entering the US for a bit, but jail time? I don't think so. I just don't see how its worth their time...maybe if you were caught with 100 of them, but one?

I have heard plenty of border horror stories from members here about being stopped with restricted goods while trying to leave the U.S.

You could face having your goods and vehicle seized, and do jail time.............whether the decide it is "worth their time" to jail, is up to them, but do you really want to take the chance?????

Lets keep things legal here........;)

The law applies equally. Thank George W. for that. Apparently the US is concerned terrorists might build Sage EBR's or something.

It doesn't have to make sense to land you @ss in jail.
 
I would be very interested to know which company is exporting Fulton Armory parts. For the recosd, FA does NOT have a State Dept. issued export license and has no interest in getting one. Their designated parts (receiver, bolt, barrel, etc.) are ITAR controlled and are not legally exportable by ANY company.

AFAIK, the only aftermarket M14 parts suppliers who make bolts who can legally export at this time are 762mmfirearms and SAI. Though tht might change as other companies start making bolts.

I am all for keeping things legal, especially when crossing the border as that can be very problematic to say the least, however, to say that if your 'caught' with one bolt you'll do hard time, I think is overstating things a tad.
 
what people do is what people do...... if they want to advertise on the internet..... who cares, thier problem. Why do we care so much about whether this fellows bolt was legally or illegally obtained.... as far as i'm concerned it's none of our business how he aquired it.
good thread and pics though.
A word of caution though...... not every usgi/fulton/sai or 7.62 firearms bolt can just be lapped in to a chinese barrelled action. There is a limit to how much lapping can be done to achieve correct headspace/lug bearing.

and for those worried about illegal importations...... has anyone checked whether 7.62 firearms has a valid export permit....... I'm thinkin they don't, but it hasn't stopped many folks from here ordering thier parts now has it ;)
hey pot...... the kettle is calling ;)
 
762mmfirearms isn't making USGI parts ;)

And what limit are you referring to wrt how much lapping can be done? Do you mean in terms of breaking through surface hardnesses?
 
Oh, and PS, nobody is busting the OP's b@lls over his bolt - the point is, some ppl will read this thread and try to import one in ignorance of the consequences. If the OP got away with it - good for him. I wouldn't want ppl to try this without knowing what can (and often will) happen to them ;)
 
WHEN IT COME TO CROSS BORDER SHOPPING FOR GUN PARTS,
BUYER BEWARE!!!

YPMMV,
however,
if you look back far enough,
you will see one of my posts detailing what CAN happen at the US border if you try to bring [ totally legal on both sides of the border ] US gun parts into Canada .... without the proper paper work.

The border agencies PROCESSES on both sides of the border are much like a toilet .... intensely retentive about paper.

Their motto,
just like your toilet training in kindergarten,,
seems to be,
"No throughput unless the paperwork is done .... properly."

My story [ ALL TRUE ] involved a GIANT balaclava masked Ninja with an M16 and a Glock, stopping my vehicle on the US side of the border, and a subsequent Kafka Like episode lasting several hours. It involved, a tiny little cinder crete block room with only one door, THREE big border agents, and my trying to convince them that I wasn't actually Osama Bin Larry.

Even though I had broken no actual laws, US or CANADIAN, I was apparently [ ?? no one on duty at the time was actually sure?? ] in contravention of some obscure and little known REGULATIONS.

Regulations not well understood by the US border agents TASKED WITH ENFORCING THEM,
NOR by the CANADIAN BORDER AGENTS ....
WHO GAVE ME SPECIFIC ADVICE ON IMPORTING GUN PARTS BEFORE I LEFT CANADA FOR MY SHOPPING TRIP.

Eventually I succeeded in getting across the border, but the US Govt kept the gun parts, and put my name on their Homeland Insecurity SH!T List ....
which made things quite interesting my next trip down to the ?Land of the Free?

You really can see the changes in the border agent's demeanor when the sh!t list comes up on their computer screen ...
and it's off to the Slow line, or the little room we go.

Interestingly,
within a year,
my name seemed to have slipped off the sh!t list, and things were back to normal. In addition, being in the Border Patrol "bad boys club", didn't seem to affect my US CCW, which came in the mail a few weeks after the incident.

So, there you have it ....
shopping advice on US gun parts from one who has BTDT,
and seen the" little room " a few too many times already.

PS: when it comes to fitting GI bolts to NORC receivers, a NEW GI bolt with a NEW NORC receiver most often laps in to FULL lug bearing within a few minutes. If fitting a USED GI bolt into a USED NORC receiver, it often takes longer. But if you are lapping for more than 15 minutes, be aware that the HARD outer skin of both the bolt lugs and the receiver is only a few thou thick.
Also,
be aware that full lug bearing on BOTH sides does not = proper headspace.

READ THE STICKIES POSTED ABOUT THIS TOPIC... that is why they are there.

And,
if you are more than .002" thou below .308 GO,
try another bolt or barrel,
rather than trying to increase head space by lapping, and Lapping, AND MORE LAPPING.

Once again,
YPMMV,
but I've BTDT,
lapping in GI bolts a few time myself,
and this is what my experience has taught me.
 
what people do is what people do...... if they want to advertise on the internet..... who cares, thier problem. Why do we care so much about whether this fellows bolt was legally or illegally obtained.... as far as i'm concerned it's none of our business how he aquired it.
good thread and pics though.

It matters because this site is monitored by Canadian and U.S. agencies.........If people are posting about illegally obtaining items, or about ways to circumvent the regulations, then that is a violation of CGN rules................and will be dealt with.................so it is our business when things that are posted seem suspicious...........

Plus people ignoring the export regulations are part of the reason regulations get tightened up...........we can be our own worst enemy at times......

So let's keep this thread on track about bolt fitting.............The OP is getting the benefit of a doubt here, and can consider this a warning not to post about any "grey area" imports from the U.S.

If this thread keeps going the way that it is, it will get locked.

Thank You.

my point exactly Skullboy. I was not advocating cross border shopping...... just seemed like the thread went from an excellent excercise in bolt lapping.... to a shame on you.... you have an illigal bolt thread.

I have met several norinco receiver/barrel combinations that will NOT accept a usgi bolt period...... and lapping in to fit would ruin both receiver and bolt...... and yes this would be due to lapping thru the hardness layers..... known for a usgi NEW bolt and unknow for the most part on a chinese receiver.

also, many of the early chinese rifles have too much barrel protrusion into the receiver and "require" a barrel change in order to fit up a usgi bolt.
for the most part, the chinese rifles of the last few years have had no issues with usgi bolt compatability, other than the obvious lapping for headspace and even lug bearing.


as an aside and totally off topic...... today i met an unfired 2009 norinco, plastic stock variety..... amazing trigger parts, excellent and bang on flash hider, indexed perfectly..... and headspace of 1.634........ .0005 under 7.62 nato match with perfectly even lug bearing....... right outta the box ;) No usgi bolt swap needed on this one ;)
