The first roll pin punch I bend is one for the gas tube. The ones in the generic kits are much longer than they need be. Here's one made for AR gas tubes. The pin part is only a tad wider than the sight base, so you get all the pressure wher eyou need it. Of course, it has the knub in the center for centering the roll pin. Made of hardened tool steel and parkerized.
The bolt catch pin, is the hardest to get to. Here's a punch milled flat on the bottom, so it lines up perfect from either side. Also made from hardened tool steel with the knub for centering the roll pin.
Hade from non-marring high density plastic, this tool is strong enough to install and remove trigger pins easily. With the wide top end, you get plenty of leverage to just pop them right out. The large end also works wonders when installing.
pop out the pivot and take down pin - piece of cake with one of these.
to put them together...
A simple 8oz., brass hammer that fits in your range bag with everything else.
