Please.
Back in the last few years of the awb i bought this oly arms 40 was one of the very first ar15s I ever bought, i got the complete gun and a bushmaster 5.56 upper(post ban config) in the deal for $750. I bought a preban gun shortly after and well the pistol cal upper kinda got put to the side since mags were expensive and not easy to find and it's a fixed carry handle upper blah blah blah. But most importantly at some point along the way the lower got one of those pretty little special stamps and full time rifle upper and was 40 upper got neglected for something like 10+years only occasionally taking a trip to the indoor range.
Now after what feels like a lifetime I want to do something with the upper.
It was always in the back of my head to chop the barrel to 8 inches. Thats about the only thing I'm full decided on. And the only thing that worries me. This gun is pretty damn accurate as is at 25 yards and Its not something that's intended for anything more then around 50 or so but I still worry something might happen in the process to fuck the accuracy of this thing.
anyway to more important things.
Its fixed carry handle and i plan to keep it that way. Fsb will have to come off, not sure if I want to keep the factory one and just slide it back or put one on the rail since the hg has to come off too but I like the standard fsb for some reason so this is still a toss up.
Yes at some point it's getting a can. It's more then likely going to inherit the aimpoint off another upper since my eyes are going to shit and its probably time to update the rifle optic from a compM anyway. Have not decided on a light or laser but both are mandatory items imo but thats for further down the road.
My main concern and biggest question is magazines.
My gun came with the old converted 41ae Uzi mag with the block welded to it to fit the Magwell. I've seen that you can send the old uppers to oly to have them redone to fit the new style magazines. Not sure I want to go that route as it doesn't look like I save any money on magazine costs. They are hard to find but when I see them the old style mag goes for about the same money. The only draw back to the old style mag that I ever really noticed was that fully loaded it was difficult to seat on a closed bolt. Would love to know if anyone has any experience with the re work and going from the old mags to the new ones. Was it worth it? Would you recommend a different route?
