| I currently host my RDIAS in a Bushmaster lower with a Colt stock, upper, BCG, etc. I would like to host it in a Colt lower, but I am not sure the best lower to use, as it appears all of them will require some modification to work. First, it looks like I will have to use someone like M60 Joe to drill out the fire control parts to the larger Colt pin spec. Then the question is do I want to have the aluminum "fence" in current lowers milled out or get an older gun with a sear block and have that milled out. After I consider all this work, I still won't have selector stops. I have thought about trying to get a deal on a cosmetically flawed Colt lower, then try to find some who can weld up and re-drill the pins, add selectors, etc. and refinish. But considering the cost of that work, I could buy a pile of Bushmaster lowers. Right now I think the best route is to get a current production receiver, have the "fence" milled, drill the fire control group, and live with the compromise. If someone has a better path, please let me know. I have heard stories about Colt lowers with mil-spec pin holes, but haven't ever seen one and I think finding one could be quite a task. But then again, maybe I will take my calipers to the next gunshow and start looking... |
With the large hole and lack of a mag fence I think green label is a second choice after modifying a current receiver. Apparenly there are "white box" rifles that have the right features, but since they were only made for a year, I am thinking it is going to be pretty hard to find one. |
You sound confused. Why would you need to drill out FCG pin to the large size? Modifying an aluminum receiver is a hack job and should only be done as a last resort. Selector stops do absolutely nothing and aren't necessary. |
I am a bit confused, but appreciate the help. Are the .170 full auto parts from Norrell better/different than other vendors who offer the service (like M60 Joe)? Interesting to hear the selector stops don't do anything, I always wondered whey they were there since they didn't seem to make a big difference in function, but they do seem common on the F/A guns. |
