Using the jig from BRD Engineering is the easiest way to pin a gas block. <a href="http://s300.photobucket.com/user/rccox/media/Guns/Burnt%20Bronze%20Noveske/B8948FA8-96FA-41A7-A763-6245FF878390.jpg.html" target="_blank">http://i300.photobucket.com/albums/nn38/rccox/Guns/Burnt%20Bronze%20Noveske/B8948FA8-96FA-41A7-A763-6245FF878390.jpg</a> <a href="http://s300.photobucket.com/user/rccox/media/Guns/Burnt%20Bronze%20Noveske/D70878E7-6C71-4436-91AB-B375DC35E963.jpg.html" target="_blank">http://i300.photobucket.com/albums/nn38/rccox/Guns/Burnt%20Bronze%20Noveske/D70878E7-6C71-4436-91AB-B375DC35E963.jpg</a> <a href="http://s300.photobucket.com/user/rccox/media/Guns/Burnt%20Bronze%20Noveske/68FEB2AD-6A34-42CA-9A3E-A8CF05456EA3.jpg.html" target="_blank">http://i300.photobucket.com/albums/nn38/rccox/Guns/Burnt%20Bronze%20Noveske/68FEB2AD-6A34-42CA-9A3E-A8CF05456EA3.jpg</a> Where do you get the pins and what size do I need? |

There are a few company's that sell gas blocks that have a dimple in them and you just drill them out through the barrel.
One company offers there's with a pin that has grooves cut into it so that it essentially does the same thing as a taper pin but in a straight hole. Pinblock The other requires you to buy a reamer once it's drilled out. You can get them on ebay for a couple dollars. Micropin Gas Block |

I bought a bag of .5" long 2/0 stainless taper pins off of eBay. The taper pins that everyone sells for ARs are too long for low profile gas blocks and more expensive.

Can you just knock the drill bit through and cut it off using the shank as the pin?

What works better a tapered pin or straight? The blocks ive seen smiths do looked all straight pinned.

I use the BRT MicroPin block (which has the locating dimple for drilling). Drill it with a 1/8 carbide bit, then pound in a grooved type A steel dowel pin (.125"). The dowel pin is the same as 87 Industries uses. There is no need for reaming/taper pins when there are "crush to fit) type A steel dowel pins out there. The only disadvantage to the type A dowel pin is you shouldn't reuse them. But since you can get them for like 10c a piece, who cares.
And the type A grooved steel dowel pins: http://www.amazon.com/gp/product/B006MKN3ME/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1 |

After bending one of them on my 87 Ind. block I reamed out the hole and used a taper pin. |
