 Just wanted to get that in the record. |

I would also like to go on record as a roll pin hater! yep... I'm a hater... Oddly the bolt catch does not bother me, but I HATE the trigger guard pin... I hear you can squeeze the daylights out of them with a pliers and then they start easier... I'm planning to do 3 or 4 lowers tomorrow, so I'm gonna try it! |
|
I also hate roll pins. I have built up two lowers, and have yet to find a reliable technique for not messing up the bolt catch pin.  The trigger guard pin has been okay though. I have found that black electrical tape is quite useful. It sticks fairly well even to oily surfaces. Wrap that puppy up everywhere you suspect you might hit it with a wayward hammer or punch. |
|
I put a couple layers of duct tape on the side of my lower and then have a helper hold the pin and the lower while I tap the roll pin with a small hammer and a long punch that allows me to tap the punch without getting anywhere close to the lower with the hammer. if you put a bit of CLP on the lower before you duct tape it, it comes off pretty cleanly. |
|
I've done 10 lowers in the last 3 months - all the same way - not one scratch. Wrap lower with thick plastic bag, secure with rubber bands, hold roll pin & small roll pin punch (from set - part number 85245520 at MSC Industrial Supply Inc.) together with two fingers and tap lightly with brass hammer to start. The roll pin punch has a small protrusion that settles into the hole to prevent slipping during the drive. Use the correct tool & never have any regrets. |
|
The ease of driving the roll pin also depends on the lower and pin combination. I had to pound the Stag/CMT roll pin into my NoDak lower the entire way. It never got any easier. I took a long time to do since I was trying to be careful. That sucker is not coming out any time soon. Also, I got scratches on my lower from the roll pin punch (yes, I bought the specific tool) slipping off the roll pin. That little bump on the end of it peened my finish a bit. |
| You guys hate roll pins. I can't stand cotter pins. And im not talking about the one that keeps the firing pin secured. I can do that by hand. If you had to do the finger gymnastics I do everyday with cotter pins you'd smile at roll pins no matter how rusty or small. |
