Trying to replace a rail gas block on my stag arms model 3 with a A2 Front sight gas block. Only issue I am having with this is that the ones I find online are not predrilled and doesn't come with a pins, spring or plunger. Does anyone know where I could fine a A2 front sight gas block that is pre-drilled and comes with all the parts necessary?
Also this is my first time doing this so I dont know what diameter front sight I need... .625" or .750" Any advice would be greatly appreciated! |

Front sight bases are rarely the same from rifle to rifle. They are drilled for the taper pins while installed into the barrel, so finding a predrilled one likely won't happen. What you'll have to do is send it off to get it done, esp if you've never done it before.
The size you need depends on the barrel you have. Most are .750 and lightweight barrels are usually .625. Your best bet is to sell the barrel you have and replace it with a new one. That's the easiest and fastest way to change it. |
| Consider buying a clamp-on FSB if you don't have the jig to drill the taper pin holes straight and you aren't willing to pay someone else to do it. A clamp-on can be installed and adjusted by the average DIY tinkerer with relative ease. It will be slightly more expensive to purchase, but significantly cheaper in the long run if you factor in the cost of buying the correct tools or paying someone else to do the work. |
