Period correct AR 15

unforgiven · February 11, 2017

I changed hanguards on one of my 15's and had to remove my A2 front sight. Backed it up with a 2x4 and hit the Small end of the pin and it came out. Just got to get a bigger hammer brother. Cut off the sight and ground it down to make a low pro gas bloc out of it. Put the cut of wheel to delta ring and spring washer to remove. Easy peasy. Just what I did. Your direction is different. A2 sight pins is the same.

I have a round delta.

That pin isn't budging.

Don't try to press it out - put a punch (that's larger than the small end of the pin) on it, and smack the hell out of it! You're not going to hurt anything,so let that fear go. Hit that thing like Ali, man - you HAVE to...

I'm going to make a jig today and try abs use the vice to press them out. Got a little work done last night. Still waiting for the buffer tube so I had to stop there.

Thats not a round one on that Barrel , its a Tapered A2, are you changing it ? The A1 is a flat round one , not tapered .

Could have Rock set on the Pins ?

Did this also! Twice! Not a good gut feeling until it works again..

yep me too I have removed them and they have to be well struck they are a press fit but will come out due to taper I also have cut off the sights and made a low profile gas block on my dissipator.....

BIGBREW · February 14, 2017

Is this pinned in the wrong direction?

unforgiven · February 14, 2017

Bro there is a big end and small end hit the small end.

BIGBREW · February 14, 2017

I understand that, but the small side of the pin is supposed to be opposite the ejection port side.

survivalshop · February 14, 2017

Unless you have a non-milspec set of Pins . (Remove -left , out to right , install -right , in to left ( ejection port side ) ) It may look like the small side is not where it should be , because there really isn't much of a Taper in the Pins , its hard to tell when they are installed . Use a med. size Hammer & use the proper size of punch to move them all the way out

I just did a Colt Factory Rifle a month or so ago & it took a really good wack to release them , just make sure the Sight is well supported , have a helper if you need to steady the Barrel assembly .

I'm just trying to confirm with FAXON which way they install their pins before I beat on it any more. It appears that they could be installed in the wrong direction.

I'll probably try adding some heat before I pound them out. FAXON said they may have applied red lock tight on the pins when installed. I just haven't had time to work on it and when I do my little guy is usually asleep and I don't want to wake him up banging in the basement once he finally falls asleep.

If they used rocksett then soaking in water overnight would help.

BIGBREW · February 14, 2017

They install their pins from left to right. The size of the pin on the left is definitely larger than the right (ejection side) look at the pictures and tell me if I'm crazy.

Like the man said get a bigger hammer Clamp the front sight on top of a short piece of 2"x 6"with a 1/2" hole, pin big end down. It may help to soak the pins with PG Blaster and let it soak for a couple of hours. I don't think you should apply any heat, just a strong punch and a big hammer, you can peck away with a light weight punch and regular hammer all day and only make a mess. One really good wack with a big hammer can be productive. I would hold the punch in a pair of Vise-Grips.

WTF ? I guess I've been installing them wrong all these years , I'm beginning to wonder about some of these Barrel makers .

98 posted this on the link on the first page, here is a photo of which way a Milspec & every other A2 type sight I have ever worked on .

BIGBREW · February 15, 2017

I told you please tell me I'm not crazy.

survivalshop · February 15, 2017

Your not Crazy , the Barrel maker is & have you tried to remove them opposite of normal as they have told you ? If they are wrong , its not going to help your Sight removal .

This doesn't help your 'Period Correct " rifle :lmao:

BIGBREW · February 15, 2017

Thanks Survival. I don't know if I want to even mess with this any more but FAXON has not offered much help.

Military rifles will all be assembled the same way. FNs and Colts. "Mil-Spec" doesn't necessarily mean that other manufacturers will still go in from the same side,every single time, with those pins. Just that they use taper pins to secure the front sight tower.

Find the small side of those pins, and hit the shiit out of them. Hard.

Have any names of Companies or barrel manufacturers besides Faxon that install them this way ? This is a first for me :lmao:

98Z5V · February 15, 2017

Who knows? There are tons of companies that offer front sight bases... I probably can't even name them all, after hours of searching company names... I doubt they all train the people that assemble the barrels, though, about a specific direction for installing front sight base taper pins - just ream the holes with the tapered reamer, and smack the pins in... I can guarantee you that the only two companies that will do it exactly to the M16/M4 TDP, every single time, will be Colt and FN... :thumbup:
