View Full Version : Century "POS" G1, FTF
April 28, 2004, 22:35
Trying to get a buddies G1 on an older Century reciever to run and I'm stuck on a FTF problem. At first I thought it was a mag or mag catch problem, but I've tested through 20 mags and 4 mag catches with no luck. This thing will fire 3 or 4 shots and them jam up with the bolt trying to over-ride the bullet in the mag and jamming it against the back of the barrel. It dosent jam against the feed ramp, but the back flat of the barrel, almost like the feed ramp was cut too low when the reciever was made. There's about .100" space of barrel flat between the top of the feed ramp and the start of the chamber lead-in bevel on the back of the barrel and this flat is where it jambs. I'm afraid to increase the chamber lead-in that much and loose all that case support. This is the only Century reciever I've seen, but none of my others (Imbel, DSA) fit or look like this. Anyone seen this before ?? Thoughts, comments ??
Thanks, YOOO VINNY

I had the same problem on a Century unibrow receiver. I will tell you how I corrected it, but I DO NOT RECOMMEND this method to anybody. *ok, now that my butt is covered* The problem is that the feed ramps are too low. They don't push the bullet high enough to clear that flat area. I took the barrel off and welded the feed ramps up with a mig welder. I then used a pneumatic die grinder ( very similar to a dremel) and reshaped the feed ramps. I made sure that the feed ramps were higher than original and then polished them.
My remedy has worked very well for over 1000 rds through this rifle.
If you don't want to weld on the feed ramps or do not have access to a mig welder (DO NOT USE AN ACETELYNE TORCH FOR THIS), then you can take the barrel off and smooth the flat area to make it more round. So long as you don't get into the chamber area, it will not take away from the case support.

That's the conclusion I've come to myself, there seems to just be a lack of material on the feed ramp. This is a design and manufacture problem, how can anyone get these Century recievers to work as made ????? I've been known to dremmel and polish a feed ramp or two in my time, but it's hard to do when there's already a lack of material there :uhoh:
Of course, I'm doing this as a favor for a buddy. No good deed goes unpunished
:cry: this thing has just been problem after problem. This is the same damn rifle I'm working on that I traded with you, to get a new bolt for. The original bolt, they dremmeled the back down to make it head space !! The angry beavers have nothing on the dumb ass that put this one together and the reciever is JUNK.

I have a Century receiver that has never been on a build and never will because of the extent of the screw ups. I saw a Century L1 in a pawn shop with your problem, someone dremmeled the barrel face to allow the rounds to chamber. Don't do that!!!

Try using a coarse Craytex wheel in your Dremel. That is the rubbery grinding/polishing wheels. That way you can round over the edges but not take a lot a material off in one shot. Allows for finer control of material removal.

Had a century receiver with the same problem. Just for kicks I built up the feed ramps with liquid steel & then shaped with my dremal. Sounds kind of funkey but it works. Colt88 :uhoh:

Well, I beveled it out a little and polished the hell out of it. It's not the best, or the way it should be, but it's somewhat better. I ran through 2 mags without a problem but it stoped twice on the third and fourth with the same jam :rolleyes: I did'nt get into the case/chamber support and the fired cases look fine. I'll let him shoot it awhile and decide if he can live with it or not. While I might weld it up and re-mill it, if it was mine, I'd rather not do it on someone elses unless theres no other options. I'd really rather have him buy a good reciever, it's his first FAL and should be right, not a century patch job. Thanks to everyone for the input.
