| I'm thinking of trading my SP-1 conversion for a genuine colt factory M16. Is there ANY differance in quality, dependability..etc.. because my SP-1 runs flawlessly with any upper I throw on using an H2 buffer at all times. Or should I just keep it and be thankful it's so reliable. I guess what I'm asking is, would a factory gun be more dependable in the long run? |
| A quality conversion from an SP-1 is mechanically identical to the M16. The receivers are both Colt, just one is drilled at the factory, and one was drilled by a Class 2 manufacturer after it left the factory. If you were comparing an after-market converted lower to a Colt M16, there might be a difference in quality. If it works, I'd keep it. |

If you really want to have a factory gun (and some people do), then go for the M16.
But otherwise, as long as your SP1 conversion is running perfectly, keep it and spend the money on ammo. It will be neither more or less reliable in the short- or long-term. Routine maintenance, quality of parts and ammo, and how the gun is used and treated are by far the most important factors in reliability and longterm durability of M16s. Treat your '16 right, and it'll treat you right.

I personally found the big front pin a PITA. Having a standard push pin is much better in my opinion. My question for you is how do you normally shoot? For me I would bring a bunch of different uppers and mags, usually of different calibers when I go shooting. I do love a Beta or drum dump. My rule is dump a Beta C or three mags and set the upper aside until I can hold the barrel with my bare hand. So having the front PP made it very easy to change uppers. If you normally go shooting with one upper and a couple of mags, I wouldn't bother.
Has your SP1 been reanodized? I've seen some SP1 conversions that are still "in the white". I would think it would be important to have the anodize surface inside the sear pin holes. Even though the anodized coating is only a couple of thousands thick, it is much harder than the bare aluminum. If your lower wasn't reanodized and is still "in the white", I would look into getting that done. Scott |
