I've used liquid wrench penetrating oil on my Bushmaster XM15-E2S and used a titanium punch with a 3 lb. hammer and can't get the taper pins to budge for $#!+

I have a Larue Tactical 7" rail I need to mount, and these pins and orange block are pissing me off!!!

@3mealsaday

Can u please tell me ur secret to get my pins out?

@moik145 Need more shock to the pin. Get a steel slate (1-2 inch thick, heavy). A 8-10mm socket. 16oz ball-peen. Punch bigger then the pins you're driving out. Grab a buddy to hold the barrel or reciever. Place the socket underneath the pin your driving out. Socket rests on the steel slate. Place punch, smack it with a good hit from the hammer. This is what I had to resort to when the bench block wasn't enough, only I ain't got a buddy. Imagine trying to hold all that at one time.

I've got a BCM upper and can not beat those f"ING pins out!!!! Don't want to take it to a gunsmith but may. Grrrr

Pins don't come out that easy!!!!!. Darn YouTube magic!!@ they make it look so easy!!!

Just spent 2hrs beating on those pins, still didn't come out!!

@mhcurlee I built a DPMS and the pins came out easily. I'm building a Bushmaster now and they feel like they are welded in there. Different brands have varying levels of difficulty. I definately need the block for the Bushmaster.

First, determine whether the pins are installed from left to right, rt to left, or are straight. I've seen all three. You'll need: 1-2lb sledge hammer, Brownells bench block, large nail set which fits over the round head of the taper pins. Fit sight tower into bench block, supporting breech end of barrel. Place nail set over taper pin. Strike once. Make sure nail set is centered on taper pin, hit again. Repeat. f surrounding areas with masking tape.

Place nail set over taper pin. Strike once. Make sure nail set is centered on taper pin, hit again. Repeat. f surrounding areas with masking tape so as not to damage the finish.

@3mealsaday I'd love to know how to line up the gas port. I am replacing my front sight with a gas block and I want to know how to do things for myself. Thanks

@weirwolfe I'd like to know how to get the pins out. Mine is a Stag lefty and the pins look like they go from right to left. It's a little hard to tell. The gas tube roll pin came out easy but now for hard part. I'm putting a gas block on so I don't have to worry about getting it back on. Thanks

I beat the crap out of my pins and front sight until 3 AM last night. F' it!

I sent it back to Bushmaster and told them to exchange my barrel and welded on FSB for one that is truly "serviceable." With the right tools it shouldn't be such a PITA for gun owners.

I hope they get me hooked up by this weekend, as I have a match Sunday. We'll see!
