Here is the issues. A kind gentleman sent me a original flash suppressor and a inch pattern magazine. It is not feeding properly. After the first round is fired it fails to strip off another round and feed it into the chamber. And I do not know how to fix this? The bolt seems to go back far enough to chamber another round. So I am bit baffled!? Second of all one of you mentioned how to fix the problem where the bolt doesn't stay open after the last round?

I really wish to make this a working rifle. I love this firearm and have a real desire to get it going.

Any help is and would be deeply appreciated .

Thank you

Oh and please no Century arms suck comments. Haha!

Close the gas regulator completely, load a round, while holding upward pressure on the bolt hold open, point the muzzle down range and fire the round. Does the bolt lock to the rear?

I will try in the morning and get back to you.

Or, close completely, load two rounds, fire. Open gas one or two clicks and repeat until the second round is not picked up by the bolt, then close gas two clicks. Same as HBR suggested, only different :)

Test with full mag to see if an extra click is necessary to over come the drag of a fully compressed mag spring.

L1A1 was changed so bolt will not stay open after last shot.

Check to see if pin is missing. That was standard procedure.

Good luck

True enough, but it doesn't have doodly to do with feeding a round from a full mag :confused:

This is not a "problem" but is actually intentional in the L1A1. The Brits decided the SLR bolt should remain closed for cleanliness and eliminated the pin in the BHO that is grabbed by the mag follower in the FAL.

Like you, I prefer the bolt to lock back on the empty mag and have modified my SLRs accordingly. You can replace the SLR BHO with a metric one or you can install a pin in your existing BHO (the hole should be there).

As noted above, this is not related to your feeding/cycling issue in any way.

OP asked about bolt hold open.

Not feeding could be bad mag, out of spec receiver, rounded bolt.

Also not enough gas to chamber round. Gas plug in grenade position?

It's fun getting them to work!:p

If You've never looked at the springs in the buttstock it may pay to pull them out, clean the tube, measure the springs, lightly grease and replace. I doubt this is the issue but crap, gummed grease and sand won't help.

ETA there is a tool for that and wear eye pro as those springs will bite you if you Fail to control them.

I'd also clean the magazine. I got some surplus ones filled with Bahamian sand before. They worked better without the interior sand castle kit.

I know you said the bolt is Moving rearward in cycling but for humouring me, make sure
The front isn't on the grenade setting. (That turns off all the gas despite the regulator setting). BTDT grin.

Got so focused on the feed issue I read right over the holdopen part - my bad !!!:(

The make and model of you receiver has a direct bearing on how to fix your problem. Whether that is a sucky Century or a not so sucky Century.

Since you probably don't know how to tell the different models of receivers it would be best to post a pic of both sides of the upper receiver.

I recall reading that FAC made some of the century receivers.

Is there any truth to that rumor?

OP's L1A1 appears to have a century receiver in another thread he started.

Also have heard getting them to work reliably is . . . challenging.

I believe 4markk started a thread on making his century run.

Wishing him the best!

Yes it stayed open. I did a few shots and it stayed open every single time. No gas setting how ever would work.every shot had the same results.

I believe many are correct in saying this rifle is not designed to lock the bolt back on the finale round no matter what magazine is in it.

Next I will provide pictures of the reciever.

The purpose of this exercise was to establish that the gas system is functioning and that the bolt is coming back far enough to extract the spent casing and pick up the next round.
Now we need to find out if the magazine is being locked in and held firmly against the feed rails.
Remove the firing pin to prevent a negligent discharge. Load a mag with a few rounds and insert it into the magwell. Now cycle the action by hand and see if it feeds the rounds.
From your comments, I suspect that the gas system needs attention. But it is working so it can wait until we discover the feeding problem

I suspect the gas system as well. I have made sure the gas tube (what ever it's called) is good and tight to make sure I am not unknowingly venting gas off. Next so you know what I am firing through the rifle..

As you can see two of the mags are very good condition but metric mags so followers and springs are in top condition. The 3rd is a inch pattern which was donated to me from the very kind JonnyP. All 3 mags are clean and lightly oiled.

The gas tube btw is clean and the piston is super clean. There is no pitting or corrosion on either.

I have purchased several Century builds over the years. Some metric and commonwealth adopted and mistreated children who needed serious therapy. Some not so bad (cough) assemblies that ran but like most American women very temperamental.

This one however seems to be well assembled and (wait for it!) The last owner had no issues.

I will get this one running because I like it and wish to hold onto it for life.

So I deeply appreciate the help!

Thank you

.Mags are clean. No sand castle which is disappointing because I would find that nifty.Gas plug is correct. Buffer spring is clean and I do have the tool and have kept all 3 of my eyes safe. ;-)

May 27, 2017, 02:14
Oh forgot to add. Gas setting on 5 was about as close to success I have had. It does not always seem to cycle back far enough to snag another round. Is it possible that the buffer spring is too stiff or the rounds don't have enough powder to create the blowback needed?

I recently had a Fal that would fire one shot and that was it. 3 top members on here (Flypaper, HKShooter, & G3isme) walked me through turning the gas tube back a quarter turn and pinning it. It was screwed in tight and therefore gas was escaping.

If yours looks like the above, then you will screw it in, turn back a quarter turn until it lines up, then pin it.

As said above, the bolt hold open in your rifle is an SLR version as I see no pin to catch the mag follower. So you are correct, it will never lock open on an empty mag. Not a flaw, just the "inch" way of doing it. To restore the feature you'd need to add the pin to the BHO or replace it with an intact metric piece.

If holding the BHO up while firing causes it to catch the bolt then there's enough gas/travel in the bolt group to catch and strip the next round. The problem most likely lays in the mag, mag catch, or eblock location, or possibly the bolt itself. Are the front lower corners of the bolt sharp and square or are they rounded off? They don't look bad in the pic but the angle isn't ideal.

I have a hard time believing the last owner had no problems with it.

I see no excessive wear on the bolt.
