Dreaded Unibrow feed ramp

[dpoe]

So I have the dreaded Unibrow feed ramp on my FAL. I was just wondering if any of you guys have heard of remedies for this or know of one yourselves.

thanks, David

sorry, had to do it
i'm just bored of packing stuff up..







by the way, a little more info is that david's L1A1 seems to be feeding a lot better with my inch mag than my metric mags, we had about 3 stovepipes on the left side of the mag while feeding when we used a metric mag. it wasn't hard clearing since all you had to do was rack the charging handle harder


with the inch mag, i rmember we loaded 10 and all 10 shot fine
we tried 2 metric mags i believe.

david can confirm this

Have you tried it yet? Some fuctioned alright, though many did not. The Izzy's used them succesfully on their FAL's I believe, but Century screwed up the design.

One guy I remember on Falfiles welded up the ramp, then cut dual feed ramps with a dremel.

Another if I recall too, sucessfully modified his mags by carefully bending the feedlips out in the front, as to raise the bullet so it never came into contact with the ramp. If I had uni and were having problems, I'd try this first, assuming replacing the receiver wasn't an option.

On the Izzy designed unibrow, I believe the mag well orientation was higher, thus the bullets never actually made contact with the ramp most of the time. This is where Century screwed up the design.

I got lucky with my Century L1A1 as it has the dual scaloped feedramps (Hesse receiver :eek:). Functions great now after a little tweaking...polishing the feed rails, replacing the mag catch, all the springs and sealing the gas system.:thumbup:

Likewise - always modify the cheapest part first :thumbup:

I assume that the rifle is having some problems as is. If the rifle functions well, forget about the unibrow feed ramp. Are you having jams as the bullet tip hits the feed ramp or lower edge of the barrel? Commonly this can occur more with rounds feeding from one side of the mag than the other. Right side jams are common, for example, but I do not know why. A standard remedy is to file or polish the feed rails so that they do not extend beyond the feed lips of mags. If the feed lips already extend past the rails and are visible in the receiver, there is no need to do this. But some polishing of the undersides and edges of the rails might help. Another possible solution is to polish or round off the front edge of the feed ramp and the lower edge of the barrel, to stop rounds from getting stuck at those points. Don't take off too much metal--it is hard to put back. Yes, you can modify mag lips so that the round is released sooner and does not jam below the chamber. If you can get one mag to work--or already have one such mag--you can use it as a model to make others function. You bend the front of the feed lips up slightly with a pair of pliers. But if you raise this area too much, this forces the rear of the round too low to be picked up by the bolt and loaded into the chamber. The bolt will override the round and cause a jam. If you raise the feed lips too much, rounds will not stay in the mag and/or the mag will not lock into the receiver. Hand cycling live ammo with the firing pin removed from the bolt and the rifle aimed in a safe direction might help. Pull the charging handle back and let the bolt slam forward. If you can get a mag to hand cycle consistently at home without jams, you may have good luck with it at the range. Watch out for jammed rounds in which the bullet has been mauled or pushed into the case. You will have to polish the bullet tips or discard the round. This mag solution to jamming takes lots of time and can be frustrating, but it is cheap and does no harm to your rifle. Mags are much cheaper than receivers.

Good luck,
