I am looking for advice on how to install the roll pin. I have a spikes lower and dd lpk. It seems like the hole on the lower is a tiny bit smaller than the roll pin and i dont want to damage or scratch the lower trying to hammer it in. Dont know if this is normal so i would like to hear how everyone else is getting this done. Any tips are appreciated. Thanks in advance.

figure out what size roll pin you have and do search to find out what size hole it needs and clean it out.

Its just the anodizing in the hole.

It is a tight fit but should go it with a little encouragement. If it is too difficult then I would suggest a new pin.

If you can't get it in PM me, I might have a pin for you.

The dd lpk is good. Wouod not worry, you need a punch and hammer to get it in. Great videos on YouTube.

Chemfer(bevel) one end of the pin till it is shaller than the hole & just tap in.

Thankyou so far for all the tips. I guess im a bit nervous especially after reading how many people have broken off there lowers ears while trying do do this. Im going to try and bevel the roll pin and but some lube on it and hopefully it will work its way in there. Its just fustrating as i though this would be the easy part.

Put a block of wood or something under the ears before you start pounding on the pin.

 

If you're impatient, skip to about 2:30

Just went to try it with a bit of lube on in and it went right in. Dont know why but this time it seemed to actually fit in the hole. Thanks everyone for your input.

If you really don't feel comfortable and you have a drill set, a small set may not have enough drills around that size to properly measure the hole but if you have a larger set try pulling the drills out and use the butt end of the drill and see if you can get the exact size of the hole. After you do that, measure the roll-pin, and then call the manufacture and see if they can tell you size or clearance tolerances for hole and roll-pin.

 

I doubt you have the wrong parts but it can happen so if it's really that bad find out first or see if someone who had done this before can take a look at it for you.
