View Full Version : 5.45 uppers help

03-06-2012, 8:12 AM
I'm loving my poly bushmaster upper but will probably upgrade to a metal/aluminum upper for the sake of durability (although it sounds like these bushmasters take a beating?).

I'm hoping for a 5.45 upper but am trying to figure out if its worth it to go piston or DI for a 5.45 upper and how hard is it to find mags for it? I figured the ASC mags (I believe thats the brand) are rated as the highest but may be hard to find pinned mags. Spikes has a upper thats coated in melonite that may help with corrosion with corrosive ammo, anyone tried it?

Oh and the budget is 600 tops.

Your best bet when it's back in stock.

regular .223 pmag work fine for my 5.45 upper, i have the smith and wesson and works perfectly.

I've heard the ASC mags work best but I have used just about any mag I had on hand with my S&W upper with great luck. You have to download the mag some but they work fine.

I'd skip the extra cost of a piston system and put it towards ammo. You'll need to break the gun down for a deep clean everytime you fire it. The piston just adds more parts to clean and from what I have seen, doesn't keep it that much cleaner. I simply flush mine with hot soapy water afterwards, dry, and oil. No rust/corrosion yet and it doesn't take long to do.

Yea I'm leaning toward smith or bushmaster. Both look nice and sounds like some pmags and asc mags work well.
