I found multiple variants After i looked. Some had been marked M-16A1, and some were being marked M16A1. Some experienced SERIAL basically stamped on there ahead of the serial quantity, and Other folks didn't.

I've seen superior effects with electroetching. It does consider some apply to have the depth uniform. I believe the stencils are just one time use so you may want to order several and observe over a scrap piece of aluminum just before looking to etch an eighty%.

I've appeared by way of two piles of old copies of Equipment Gun Information and previous Firepower Publications, I'll retain seeking or I will simply call LMO and see if I am unable to discover the write-up, It experienced photos and everything.

We can easily Establish off of it. Open up to other ideas likewise. It would be pleasant to find the timeline for the mess which have been the 601 barrel markings. I’ll in all probability include excess shots as examples of some things.

I think the one which went for $801 is as it had the rear fifty percent as well which makes me Believe whoever bought it will attempt to splice the two alongside one another which is a giant no, no.  Another just one went for $904 mainly because of the uniqueness of having the raised “+” about the partial fence and being in the five hundred,000 serial variety assortment, you Under no circumstances see them.

Damn, I haven't got a router. Merely a drill press. I could chuck an conclude mill into my drill push although. I like utilizing the matter being an ersatz mill.

By the point I pay out myself again for your instruments, purchase Each individual blank, stamp them, wreck some along how, spend to ship it to my CNC male and fork out him to laser/Reduce over a variance, ship it back, log it, hand polish/debur and QC, ship to the most effective anodizer in the US for gray and pay out him, ship it back yada yada yada $five hundred would seem low cost.
