How the hell do you get the front sight pins our from factory stag upper?

[Paulinski]

I tried hammering them out and they won't even bulge. Yes I was trying to hammer them out from the right direction too. Nothing nada they won't come out. My punches were bending but the pins are stubborn. My wilson barrel only required two solid taps to get the pins moving?

Cheers

No, not from the right direction... the left!

Stag, CMT, Colt and LMT use milspec Taper pins put in with a machine press.

The best method of removal is to use a custom front sight removal block (A piece of wood routered to fit the front sight gas block and with holes for the pins to be pounded out thru. -- credit to Dave Lutz VP MIL OPS for KAC and ret USMC LCol for that one).

To start the taper pins use a stout pouch, and not a punch you would normally use on an AR.

front pins

Ya a proper front sight block would be nice ........, but I found a lead block and a carpenters punch(tip recessed) works good too. Use a decent size hammer ie 2lb+ for a good solid hit, 1/2" poly makes a good spacer for under the sight.

Thanks for the info. I'll guess its wood working time.

I am in the process of doing 15 Bushmasters that were the tightest I have ever seen. I have done many before and never had a problem. I am not a novice at it.

Anyway, the only way to get them out was to set them up in a milling machine, face off the head and drill the centres out just under 1/8". this relieves the pressure and then the hollow pin was able to be tapped out.

It was a pain but it worked.

So Wilson Barrels are not milspec?

I think Kevin was referring to the taper pins used by those companies as being milspec (dimensionally) - has nothing to do with the make of the barrel...

hsld.

Duh.... Now that I compared both taper pins I see what he meant.
