Any person who has built an AR-15 lower knows the frustrating aspects that can make or break an AR build. Some frustrating elements include the starting of roll pins for the bolt release, trigger guard and the windage drum on a carry handle, let alone the countless other roll pins a firearms owner can encounter over a lifetime.
To alleviate these frustrations, Brownells introduced its Roll Pin Holders Set. This set of five roll pin holders is all builders need to start every roll pin found in a typical AR-15 build. The set includes holders that accommodate the following roll pin sizes: 1/8 inch, 3.5 mm, 3/32 inch, 5/64 inch and 1/16 inch.
The 1/16-inch roll pin holder features a machined notch that allows builders to clear the windage drum when setting a windage drum roll pin. The 3.5 mm roll pin holder is designed to assist in holding the pin found on the breech block of SIG Sauer handguns.
To use a roll pin holder, simply place the roll pin in the end of the holder. Start the exposed end of the roll pin into its designated hole, and gently tap the opposite end of the holder. Once the roll pin is started, remove the roll pin holder and then use a roll pin punch to seat the pin the rest of the way. Brownells warns against using the roll pin holder to fully seat a roll pin. The tool will mar the surface of the firearm if driven in too far.
The complete set of roll pin holders from Brownells is available at a suggested price of $49.99.
