Got a few small nicks.  Anyone know what might be helpful to cover it?  Made me a little sick.

thanks

Sharpie. Or, if I had ever done that, ignore it.

It's what engravers use when they do NFA engravings.

Throw it down the driveway a couple of times. You’ll never notice them.
It’s a damn tool, not a beauty queen.

Put some painters tape on the area next time.

I know.  I guess being this is the first lower I goofed up, it kind of sucks.  But I bought the upper in 21 and it's unified. It has beauty marks all over it.

I'll get some of that.  Thanks!


anyway, I'm happy with it.  The only non larue part is an a2 grip I threw on it.  I'll order a smooth larue for it.  The upper is the march upper that I bought in 21.  I'm excited to shoot this rifle soon.  I'll see how accurate it fires.

Or don't use a hammer.  Nothing on an AR15 needs a hammer to be put together.

Toss it down the driveway a few times, sand the sharp edges, rattle can

I did my first AR with a hammer.  Back then all I had fit in a small tool box.

Now I have a garage with many tools.  I use flat-faced parallel pliers, a vise, and a 2T arbor press to assemble.

OP: sorry about the nicks. I used Sharpie but it wore off quickly.  Try that aluma-stuff.  I should probably try it too!

This. Also, you can use a couple layers of Gorilla tape on the side of the receiver to avoid this in the future.

I think electrical tape takes a little more abuse.

Also, that pin can be pressed in using channel lock type pliers with tape on the grooves to protect the finish.

Have used both and agree 3M electrical is tougher. That said, I've done multiple layers of painter's tape and it typically worked fine. But I have slipped with the punch and/or hammer and torn through the painter's...

While I get it, they're tools, I try to keep them nice.

Sharpie looks kinda purpleish when it dries. I’d leave it if it were mine, but as said aluma black, Krylon or aluma-hyde II from Brownells would all work. Or get it all cerekoted whatever color you want.

If you throw it down the driveway a couple of times, it’s like stolen valor.  

I try to keep my tools in the best shape I can as well.   A well cared for tool is a safe tool.

Yeah I’m in the press with channel locks camp. I bought some smooth jaw ones for this purpose. I also use electrical tape to avoid marring.

Channel locks with some tape on the jaws. Gently Squeeze it right in

I bought a special punch for the bolt catch pin, it's milled flat on one side to help not make contact while allows you to keep it straight/square on the roll/spring pin.

Works good. Haven't mastered the pliers method. I chewed up the lower, even with tape on the jaws.

Shoot it a lot and add more matching scratches.
If you don't have a plan, you can't change it.

Oh man, it's been years since building a lower.  That's how I've done them years ago.  I completely spaced on that.

It’s my only way to assert dominance

Plus after putting together or switching out bolt catches for phase5 levers on LaRue Heavy lowers, punch is second nature now.
