    We need a piston v. DI sticky thread, and just lock all the other ones.

    :|

    This is getting really... not so smart... these DI v. GP threads are better left to TOS.

    I still regret arguing for the pistons in 87GN's thread, as I am wholeheartedly a DI believer now.

    The problem with stickies and that NO ONE reads them. The SEARCH feature is hardly used as well.

    Thanks for all the replies gentlemen. The feedback was definitely useful. I'm a LEO out here in California. So besides the department AR's we never really get to play with them, or customize them that often. So forums like this help me out greatly. I'm just happy to finally be able to get my hands on my own AR. It amazing how many things they make for it.

    So far for my M&P15-T I've bought Eotech 553, Vickers Blue Force Sling, and some other minor sling mounts. For duty use. Does anyone suggest any other upgrades? I was thinking about another stock, and charging handle. Like I said, there are so many options.

    Buy ammo and shoot the hell out of it. You will only then know what you want.

    Forget this silly nonsense about piston conversions.

    Right.

    The creators did a dis-service by calling it the "direct impingement" operating system.

    They should have called it "integrated piston" or "inline piston" or something like that.

    As a piston owner...don't bother. Not that there is anything wrong with my piston gun (LMT), but because you won't really get any benefit from the $350. Unless you get in a firefight so long you shoot the gun dry (which isn't likely in LE, and .mil guns are still DI anyway), the piston can't really help.

    Spend the $350 on ammo or towards training. BCM Gunfighter charging handles sure are handy tho...and only $44.

    I would say throw in a BCM Gunfighter.

    If you do spend money on ammo, the CH will break eventually if you run it kind of violently. Standard GI handle is kind of flimsy.

Does NOT limit you to a 'clamp-on' gas block depending on manufacturer.

    There are other issues though like carrier tilt. Some say they have remedied it. I do agree that there is currently no standardization amongst the manufacturers.
    Less cleaning my eye. You now get to clean not only your receiver and bcg, butalso your handguard or rail and front sight and whatever other crap is hanging up front. Still have a bolt and carrier to clean. Still have crap in the upper. The 'so much easier to clean!' nonsense is just that.

    Types of steel. Who uses what? Is somebody using 8620 or 158 in their carriers or bolts? Could yougivean example of a piston manufacturer using the same or better quality as a gi counterpart? Fair enough on the clamp gas block comment, however a popular piston system does rely on it.

    I just don't see why some view this idea as an 'upgrade'. It's a step backwards in my opinion.

    Oh!

    Wasnt even aware they had kits that offered method conversions. I would be impressed if it wasnt for just buying a piston system off the bat. I wouldnt feel too secure about changing out my stock operating system. Not on a reliable weapon i routinely use/rely on anyways. Maybe on one i dont care much for (wheres that little Red Ryder BB gun)
