| Gathering up all the tools I will need to put a Larue handguard on my Bushmaster. Just wondering if you need the roll pin punches or if a regular punch will work. Also how about the roll pin holders. |
Roll pin punches and holders are the way to go. The roll pin holder helps you get the roll pin started, this is especially helpful with the small roll pins. The roll pin punch, keeps the punch centered and prevents slippage of the punch off of the roll pin, preventing marring the surface of what your working on.The roll pin punch can also help you straighten up an off kilter pin if done correctly. Once you use them, you will not willing go back to a plain punch. I bought mine from Brownell's and they have proved to be worth thier weight in gold ( the punches and Brownell's). Brownell's is an excellent company to do business with and offers many products you can't find anywhere else. Excellent CS and cheap fast shipping. Get the roll pin punches and holders (they work for all types of guns), you'll be glad you did.

Roll pin punches should only be used to insert roll pins. The difference between rollpin punches and standard pin punches is that the rollpin punch has a raised center to prevent the punch from sliding off the pin during installation. Some typical rollpin useage on the AR would be: - Bolt catch - Trigger guard - Forward Assist - Windage Knob |
| For all my roll pin needs I use something call Robogrips. The are like visegrips but automatically adjust for the job. I wrap the teeth in electrical or duct tape first and have not had a problem with a roll pin on a weapon build yet. Not only does it work, but it has never marred the finish or had me sweating bullets with a mallet thinking one bad hit will mess up my beautiful build. Just a thought, and while I prefer the visegrip method I have done builds using regular punches and specialty punches and could not justify the cost unless you are building a lot (as I build quite a few, I still feel the visegrip method is not only sufficient but actually superior to the punch method). |
| Are all roll pin punches created equal? I'm starting my first build, as soon as my LPK arrives. I have a gift certificate from Home Depot. Do you think I can find a set there that I can use? What size punches will I need for the LPK and Lower Receiver? Any brand suggestions? Also want to buy a good hammer for the build. Size? Rubber head? Brass? Thanks guys. |
www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=5551&title=ROLL%20PIN%20PUNCHES #1 through #4 is all you need. These seem pretty tough. But you shouldn't have to hit them to hard anyways. Use oil on the pins and take your time. About the hammer. I guess a brass one will do. I have been using a small ball pein hammer I've had for years. I just use masking tape on the side of the receiver when installing the bolt catch pin. |
