I am in the process of buying a Colt M16A1/M4A3 sear gun. Does anyone know if we will have access to the full auto picto 416 lowers like the way we can get G36 and UMP lowers?
Does my question make sense? If we can't than there is no way to utilize the sear in it. I am new to full auto M16/AR15 type weapons so I am not sure about the specifics of moving it to a 416/417 whenever they come out
Thanks
As in an M16 registered receiver? Or an RDIAS? Depending on what you're purchasing, it could go either way. If it's a registered receiver (I'd hesitate call it a sear gun as almost all AR lowers are RDIAS compatible), the receiver is what is registered and has the tax stamp, not the auto sear inside. It'll also have an extra hole in the receiver for the standard auto sear. The sear itself is not the registered item.
On the other hand, if you're buying an RDIAS (Registered Drop-In Auto Sear) then you're actually getting a registered sear that fits in any standard mil-spec lower. It's a block that imitates the auto sear in a F/A receiver, and there is no hole in the receiver for the auto sear. This is the same concept as a Flemming sear in an HK.
If you're purchasing the receiver, short of having a Class II overweld and remark the indicators with pictograms, you can't do anything about the lower. Since the receiver itself is the registered component you're stuck with it. You can put any upper on it that you want, but you'll never be able to have a F/A HK416 as it'll be a Colt lower.
If you're purchasing an RDIAS, you can put it in any mil-spec lower that will accommodate it. In this way, you could have a F/A 416. It won't be the same as a real factory F/A as it won't have an auto sear in the trigger components and no hole in the receiver for such. It'll still be F/A and still an HK F/A, just not manufactured from HK as F/A. It's kinda like putting a sear in a 94. Sure it's a F/A HK, buuuuuuuuuut.........
