I don't have the upper yet but it seems like unless I get something completely NY ban friendly whatever I order will be coming with a bayonet lug attached. I am assuming the process is self explanatory but I was just wondering how you all go about refinishing the exposed steel afterwards, I am aware that you could just blue it but has anyone stumbled across anything more durable than cold bluing?

Cold bluing should be enough with a few coats unless you use your rifle as a shovel.

I cold blue after milling the whole piece off on the Bridgeport. Several coats darkens it nicely.  I have seen permanent black marker used as well

Aluminum black

Looks like I found a good reason to break out the dremel.

I guess thats true, I could always go over the blueing with a permanent marker if the color bothers me too much.

 

I sure hope thats what you meant and that people arent just using the marker alone to resist corrosion.

Degrease, heat the metal (like with a hair dryer) several coats of cold blue and flush with Very hot water to neutralize.

 

Oil well and you'll be fine.

I keep seeing mixed feelings on it, but Birchwood Casey has a felt tipped marker for this kinda thing. I actually picked one up for the exact same reason you're stating here, I cut the bayo lug off a new upper to make it NJ compliant, then used the marker to cover the exposed steel. Came out pretty good. A lot of people say that it comes off easy (obviously much easier than cold bluing) but because of where it's located, I've never had a problem so far...

 

Currently on Amazon, Birchwood Casey Super Black Pen goes for about $9 + shipping.

I did the same dremel the bayo lug then black sharpie the spot I oil it never had a problem

 

A Dremel and a Birchwood Casey "pen" was all I used to exorcise the evil demon from below the barrel. 

 

Now granted this is not  a high end AR and I wasnt too overly concerned about the finish but I cared enough. I put this together with some of the least expensive parts I could find simply for the experience and the fun of it. I think it came out pretty good, the black looks nice and dark and covers easily. 

 

... to exorcise the evil demon from below the barrel. 

Good way to put it.

Did the same exact thing

You guys are lopping off the whole lug! Why? Isn't shaving the ears sufficient?

I've heard that however I don't feel like having that conversation with any LEO regarding the details of my bayo lug having ears or not. If the dremel is out and I'm rendering it inoperable then might as well go all the way. I may actually pull the block off and remove even more if I have the time.

I wasn't 100% sure about what I needed to cut exactly... better off for me to do the whole thing.  Was only 1 single cut anyway... and smoothing out the large flat surface was easier.

Since the statute does not define "bayonet lug" and one without ears cannot lock a bayonet onto the rifle, it can still be secured to the ear-less lug with a piece of duct tape.

 

Do yourself a favor and take the entire lug off, just like the compliant models come from the factory.

How about railed gas blocks? A pistol bayonet can be mounted on one of those.

That's perfectly fine... and legal.... it just doesn't have an evil metal piece protruding called a lug!

There is no law that says you cannot have a Bayonet on your semi auto rifle. It just says your Bayonet lug is an evil feature.

How many people you know are going to give up the pistol grip on their AR for a bayo lug?

I wouldn't. But if you shaved the lug off the barrel and mounted a Bayonet on a rail somehow it wouldn't be an evil feature.

What if a bayonet was mounted on the lug, then it was tac-welded in place. Does this not make the lug just part of the barrel, not unlike welding on a muzzle device or pinning a stock. Hmmmm

Then you'd want 12 of us on your jury.

Otherwise, don't forget to grab the jar of Vaseline on your way to court.

If you try it and it doesn't work out, I'll deposit some money in your comasary for soup packets, soap-on-a-rope, & smokes lol...

Kev, did you happen to check mine out on Sunday?
