    Which pinning jig do you recommend? Most I've seen, like the BRD's, are kind of pricey if you are just doing one.

    I like the Geissele Automatics - Carbon Steel Gas Block sold by ALG Defense, it is normally $39.00, on sale today for $33.15. Geissele doesn't sell it on the Geissele Automatics website, just his wife's. https://algdefense.com/carbon-steel-gas-block.html

    The reason I go with this gas block is the fact that it is set up to pin with a drill press. I dimple the barrel for both set screws, lock it down, place it in my drill press vise, and using the McMaster Carr drill bit Geissele suggests, drill and pin. A simple operation that doesn't require much in the way of equipment. I'd be willing to give it a shot with a hand drill in a machinist's/drill press vise.

    Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee

    Ive used the BRD devices with great success. I also build quite a few rifles a year so the cost is amortized over the course of time.

    Slr rifleworks also makes a dimpling jig that is way more affordable.
    You are a genuine toolbag if you have your EDC "loadout" in your signature line...

    if your building from scratch or buying new, i say go pinned or go home. daniel defense and alot of others seem to think its superior and only put pinned blocks on thier barrels. id like to agree to that without ever really pushing a rifle so hard to tell a difference...which i dont think is possible though... on the other hand, bcm, sionics and others swear by dimple+set screw with some red loc-tight. lots of master armorers and master "companies" will have difference in opinion here. this is why i miss will larsen (iraqgunz). he would have ate this thread for breakfast in a grumpy in your face blunt force trauma style lol. he hailed that dimple+set screw were supperior. bless his heart. miss that guy
