    The piston uppers are neat, but the price is what sucks. If the piston manufacturers could put out a standard piston upper that was about the same price as a DI upper, it would be a good deal, but I wouldn't and won't spend that kind of money for something that isn't broken. I'd rather use the money for ammo and training.

    On the 6.8SPC issue. I seriously doubt it will ever get adopted in any serious way by the Military other than what it is aleady used for. That is unfortunate because this round is a big step up over the 5.56. Unfortunately politics always gets in the way of things. If more LE agencies started adopting it, it would help it out tremendously since it is an ideal LE round.

    I could only find one post. He mentioned ONE LWRC that was jamming in one of his classes I think.

    Vickers seem to think it's okay and I think maybe Paul Howe too I think...

    Pushed hard =???

    Like 500 rounds in 2-3 hours?

    Just curious, because I just bought one and want to make sure it runs.

My observation is that it extracted too early in the firing cycle so that the chamber actually got dirty faster and started causing fte's at a much lower round count than an equivalent direct impingement gun. The crud in a D.I. gun comes from the gas tube, whereas the crud in my LWRC came straight back from the bore, which was still under pressure when the bolt unlocked, especially when using a suppressor.

    So the bolt/carrier looked cleaner, but the gun was more prone to and sensitive to a dirty chamber.

    But, I admit I was only around 3 or 4 of them for any length of time and only owned one. The 10.5" chrome-lined LWRC guns seemed to be much less prone to fte's than longer barrels and/or stainless chambers.
    maybe I shoot my DI Stag too and compare how fouled their chambers get.

    I suck at searching the net or forums. Should I search for piston rifles or for Pat Rogers?

    The problem with learning about ARs right now, is that there is a lot of "stuff" out there, that is chaff. Pistons aren't necessarily better than DI, and the 5.56 isn't that bad of a round. How can a person tell what is good information and what is junk information. I am trying to learn, but there are so many ARs and opinions and reviews. All I want is a good rifle that I can use for HD, range shooting and some time in the future competition.

    Question for you: I see you've discovered the 6.8 SPC round. I think it's kind of nifty, myself, but what do you know about reloading? Nothing. Unless you want to chunk down .50 to $1 a round, I don't think it's a good round for anyone except for an experienced reloader.

    And then, there are 6.8 SPC rounds out there that will be incompatible with whatever gun you choose. Do you know how to tell the difference? Of course not.

    Again, I understand your tentativeness on this subject, but a basic 16" carbine is what you really need, imho.
    Thanks for your input. I have actually talked to someone about building me a DI rifle, but I want to make sure I am getting the most for my money.

I shoot alot of drills with mine. I get it very hot, and dirty. Mag changes, movement drills, in the rain, had dirt and sand on the piston, I have yet to hurt it. A lot of people didn't like the idea of a new style of rifle when it first came out, bashed it, and said how much of a piece of junk it was, the M16. How'd that work out. I think the future of US fighting weapons will go 6.8mmSPC, and Piston, in the M16 platform. I've been hearing from folk who know {not who have friends who heard something} that 6.8mmSPC is about to go big. My next AR will be a piston 6.8mm. I think people need to get away from the idea that piston guns are around so you don't have to clean or lube it as much. May or may not be true. The facts I like about them is that the bolt doesn't get hot, so there are no drastic heating and cooling inside the weapon, less to no carbon in the action, less muzzle rise. The one LWRC I have is in 16in, the other is a 8in Personal Defense Weapon. The LWRC PDW 8in is usually in 6.8mm, mine is in 556. Not gonna be my first choice of fighting weapon, but should be fun. For a fighting weapon I'd go with a 16in.

    But as asked, a 10.5 or 12in suppressed 6.8mm piston gun would be the ticket and one of my first choices for CQB. YMMV
    Thanks for your input to the question. It is nice to hear from someone who actually own and use one of the piston rifles. I dont konw if I have the money to buy one yet, but some time in the near future when I learn more about ARs in general and piston rifles in particular I will take the dive. I have to start at the bottom and work my way up in AR knowledge.

I'm sure that Piston AR's run fine for their main purpose but you could get a very good DI AR plus a decent optics for the same price. If you were dead set on spending that much money though you could get a semi custom or custom AR for the same price or probably less.

    When you think about that you would pay $2000 or so for a Piston AR and about $1000 for a LMT (or about $1200 for a Colt) then it's not as good of a deal as it seems. Also if this is your first AR you need to think about getting extra magazines, ammo, a light if it's a defense weapon, optics if that's how you want to run it, and a training class wouldn't be a bad idea as well. That can diminish the price difference quickly but you have a fully functioning weapon, accessories that will last your for a good while depending on your shooting habits, and good training that can possibly save your life.

    It's just an idea to throw out there but something to think about nonetheless.
    Thanks for taking the time to add those ideas to the forum. I some times get caught up int he hype of what I am learning and forget that the basics are the foundation and that is where I need to start. Any suggetions on what is a good, upgradeable in the future, DI AR for a new shooter?

    Let me know what you think of your LWRC and how it functions over time. I would just like to know what someone who actually owns one thinks of the rifle.

    I think the main advantage is that it's easier to wipe down the carrier when you clean the rifle.

    If that's worth an extra thousand or so, then go for it.

    Here is a quote from Pat that pretty much sums it up.

    Yeah, I think I am going to get a good quality DI AR and go from there.

    An XCR is not a LWRC upper and has little in common with it.

    The only info applicable to the LWRC product is info on the LWRC product.
