AR assembly problem......

You can touch up any marks on your receiver with Alumablack.

Any tips on a good file? I bought some punches from OSH to put it together, since when does a high carbon punch bend when driving a roll pin in?

It's aluminum, so it's not going to rust.

Untreated aluminum does corrode - that is why it is commonly Alodyned.

When you hear a suction pop when you pull out.
There's no such thing as too tight.

CLP?

Cleaner, Lubricant, Preservative

You can take the tip (not the ink cartridge tip) off a clicker ballpoint pen to align the pin in the hole then you can use a larger size punch that fits in the pen tip and just smartly push the pin in the hole to start it without a hammer, or you can do it the harder way and use a needle nose vise grip and gently tap it in with a plastic head hammer. These 2 ways you wont damage the finish. Don,t put duct tape on a steel hammer head it does not work. Tape up that whole side of the lower around that hole and you should not have a problem.

Have you checked the parts for flashing/burrs?

Bolt catches are all molded. It could be a little oversize if the mold was'nt clamped up all the way when it was shot. OR the cutter was dull when the slot was machined making it undersize. File on the bolt catch before filing the anodizing off the lower. You can touch up the finish on the bolt catch with some cold blue or reparkerize it if you have the skills!

Where does one gain these skills?

Practice makes perfect right?

Filing is time consuming...I had a tight bolt catch also...just brought out the dremel tool and used a rough sandpaper disk to thin down my bolt catch. It went relatively easy and quick. All I have to do is get to my buddy's house this weekend to use his bluing solution to cover the shiny metal.

I misread it as bluing or parkerizing the lower.

file on the catch only.

[Olav]

I had the same problem.

I just replaced the bolt catch with another bolt catch from another LPK I had sitting around.

Bobula, I know I'm a little late here, but if you need an appropriate file, I have several jewelers files on hand and even more to choose from at work. You're welcome to use whatever you need any time.
