    Built both on my own. This thread your speaking of is going to get kind of silly really quick, but I'll play ball.

    The DI is a proven design in the ar. It works. The piston is "fairly new" to the ar? There are highly polarized veiws on each. Hence, the resulting silliness.

    I'll paraphrase myself again. Both work for me. Pistons not the holy grail and it's not the anti-Christ. Its a rifle.

    I'll take some salt with that. In any case, it is far beyond the average life in any case. It also doesn't do anything to bolster the case for getting a piston.

    Gummed up quicker and more due to excessive blow by experienced when shooting steel cased ammo. Cheap build, as well. I'm highly surprised that it went 15,000 rounds without issue, if that is true. Bravo Company's Filthy 14 made it to only 13,010 before having an extractor spring replaced. Not saying thats not incredibly impressive... Just surprised that a Bushy/RRA-level build went 2,000 rounds more on its spring.

    Exactly right. I remember the time when they broke the news that the Marine Corps was going with the 45 G.A.P.

    Likewise, the Firearmblog spends way too much time discussing boogereater guns (like Variants of the Taurus Judge), parrotting things it read on messageboards, and printing articles by guest writers with questionable knowledge--I checked on their today and the guest writer is bragging about the .357 magnum being rated at ". Using Federal 125 grain JHP it’s a formidable gun. This load is rated at a 97% one-shot stop if you do your part.": http://www.thefirearmblog.com/blog/2...fect-revolver/

    Another reason to not want a Judge. So I won't be a boogereater!

    Alright. I'd like to see an objective, closed sticky entitled "Piston vs. DI" or something along those lines that contained only information, not any opinion. But. Whatever. Oh well. We'll get by without it.

    As a noob to the site not a noob to the AR15/M16, I think it would be good to have an informational sticky listing/comparing the different manufacturers. I have 2 of each and I think both systems have merit.

    When I have been asked about piston uppers or rifles and I always suggest they buy a quality DI upper and a AA kit that way if they don't like it they can convert it back easily.

    Getting the AA op rod bushing out of the gas tube port in an upper is damned near impossible. In fact, I think it just might be impossible. I had to buy a new upper when I wanted to switch back to DI from my AA kit. Not very expensive, just a bitch to have to move the barrel, forward assist and dust cover... When I could have saved $90, not done any work and had a better gun by just sticking to DI.

    I don't think it's a bad idea, I just think it's a bit of a pipe dream. Ultimately it won't stop people from starting new "should I get a piston or a DI" threads weekly, but it would provide an easy place to link them to before locking the thread.

    I haven't done a "member survey" hardware thread lately, maybe I should do one on operating systems.

    If someone wants to do it, knock yourself out. There are quite a few different designs and no standards when it comes to the piston.

    You are right about some being a pain, some you have to beat into place and others like my colt you have to use loctite on or they will fall out. I have removed 2 from BCM uppers easily but my stag would take alot of force.
