L1A1 Unmarked Imbel Receiver Question

A question for the board members.

I thought that I remembered a listing of upper receiver serial number range for unmarked IMBEL receiver used on Century L1A1's but I have been unable to locate it.

I have the opportunity to purchase a Century L1A1 thumb hole stock rifle. Sellers says that it was an IMBEL upper receiver. Just wanted some confirmation.

The serial number is on the magazine well and is 109XXX.

Appreciate any info on the receiver and on the rifle in general.

Probably had the dot matrix sanded off, which is legit.

I just recut one in the same general range.

You just need to check if its a FAL or L1A1 mag well, as they did both. Different people value "correct L1A1 mag" and " cheaper fal mag" differently

Thanks for the information.

From the information provided, it is an IMBEL.

So were the receivers IMBEL marked and then the markings removed? Any thoughts as to the reason why?

Because there is no federal law prohibiting it and some people find CAI on their receiver to be offensive. The dot matrix is shallow enough that it can be removed without damaging anything else. That's why I sought out those receviers form my conversions. Could not do it on a gear logo.

Is there a preferred method for removing this offensive mark?

I use a disc sander and 80-100#, followed by a coarse (brown) scotchbrite. Be careful to stay away from the edges to avoid rounding.

if you are not skilled with a disc sander and you could draw file it that way you have less chance of making a mess of it

draw-filing is an art in itself. I will never again do an octagon barrel!
