    Alright guys I've been reading every thread I can find on this subject. I am either going to buy a AR already complete or try to put it together my self. Problem is I'm a complete newb to the AR platform. So bear with me please.

    I was wondering if anybody has a piston driven riffle AR and are they happy with it? Any problems? Any regrets?

    I going to use this gun or guns to try to protect my family and property if the SHTF. My concern is what if gun oil becomes hard to find, it's my understanding the standard AR needs to be ran wet and cleaned often. I don't know if you have to oil it before each use if you have not fired it after a period of time in a vault.

    Any one that want to straighten me out please do so. I just am a little worried about accessibility of supplies if I run out.

    Thanks in advance guys.

    If gun oil gets hard to find for your DI, pull a dipstick out of your engine and use the oil on the end to coat your bcg.

    I'd only recommend a piston if
    1) you anticipate storming the beaches of Normandie.
    2) you like doing 100+ rounds mag dumps...often.
    3) you don't mind waiting if you ever need replacement parts.

    4) you don't mind carrying fewer supplies in exchange for the extra weight of your AR
    5) you have some inside track to obtain proprietary parts for your piston gun.

    I own an LWRC and it's great but it's heavier and parts would be harder to find in the scenario you supplied.

    I see you point on parts seeing that piston AR are not common place.
    What is the cleaning schedule of the DI AR. Is it really that bad on having to run wet and just how dirty does it have to get to be a problem to cause a jam or misfeed. I do not plan on any mag dumps.

    Thanks for the info.

    Agent and MJ pretty much covered it. And the dipstick trick has been used at least 100 years so don't worry about gun oil! Anyway we used gasoline and engine oil in Nam to clean and lube since you always had that.


    I'll add another to the list:

    6) You don't mind that your proprietary piston design became an orphan after the great piston shakeout of 2012 (or whatever year). Remember Beta vs. VHS? Windows ME, BOB, Laserdisc? SACD, HD DVD? DLP?

    It's not just pistons, it's the proprietary designs of piston ARs. Some will be successful and many will end up orphans as their designers discontinue support due to flagging sales.

    There is no set cleaning schedule to the DI AR other than when necessary. Same with lube, keep it lubed properly, read the manual, figure it out like everyone else. It's not rocket science it's common sense.

    Google filthy 14 for just how long a DI AR can go without much cleaning. Note I said cleaning, not lubrication.

    Alright that made my mind up for me. I be sticking to DI. I was worried that you have to clean it every time you shot 500 rounds through it or it would start to jam.

    Let me ask you gentlemen's opinion on the cost of buying one out right vs. building one. Can a fellow save some money building one or is it a wash either way?

    I'm no expert by any means but I'd say its a wash check out some of these prices.

    Thats gonna take some homework on your part. It all depends on the configuration you're after. However, there are great benefits from building your own lower receiver at least. Being familiar with all the small parts in an AR's lower will come in handy if you ever have a problem. check this out http://www.firearmstalk.com/entries/A-First-Time-Buyers-Guide-to-the-AR15.html

    I own an ArmaLite AR10 DI, and an LWRCI M6A2 piston. Both systems are outstanding, and I like them both equally...but for different reasons. Many of those reasons have been stated already in this thread.

    If you buy or build a quality gun, it's my opinion that you will get a lifetime of enjoyment from either type.

    Just my opinion, and the concerns raised above re: the piston system are all certainly valid. That said, the reason I even own a piston gun is this...

    I'm kind of a clean freak, and tearing down that ArmaLite is a NASTY endeavor. The piston rifle is MUCH cleaner where the bolt carrier group is concerned. And the first time I saw a BCG taken with bare hands out of a "just fired, still smokin'" piston rifle...well let's just say I was sold.

    But I have the luxury of owning both. Otherwise, I'd prob just have a DI.

    I hear you on that, I will have to make a parts list I guess and do the math.

    Let me run this by everyone for quality brands. This is what I've come up with as name brands. Stag, Bravo, Colt, Palmetto, RRA, and LMT. So after all my time reading threads, if I stick with these brands, I should have a quality gun right?

    I've been looking at guns and was at a gun show in Dallas and come across a brand called SOG armory. Now like I said I'm a newb to AR platform but these looked like nice guns. Has anyone heard of this brand or is this one I should forget and stick with the names I mentioned earlier.

    Okie,

    Let us put your mind to rest regarding cleaning supplies.
    We have spoke about an excellent AR Lubricant here on the FTF in the past. I will give you the formula that I use and we have used at the State Academy for the AR Patrol Rifle Instructor Certification Course for the past 10+ years. You may chuckle, but it is simple and some of the best AR and M-16 Lube you could ever want.
    First go to Wal-Mart or an RC Airplane/Car Shop and get one of the red plastic containers you put RC Fuel in or a 2 Cycle Gas container at Wal-Mart. All it needs to hold is a quart and a half!
    Here is the formula:

    1 Quart of Mobile One Synthetic 15W50 Motor Oil
    1/2 Quart of Mobile One Synthetic Transmission Fluid

    Put them both in the container and shake it up! You now have a whole Quart and a Half of the best lubricant you could ever buy for the AR Rifle! It will not cook of as well as protects the parts and the Trans Fluid has just enough detergent in it to keep the carbon down when using the rifle! And compared to what it would cost you for a quart and a half of regular gun lube it is very, very inexpensive! :D

    That's what I was thinking when I heard about the piston AR. I was was under the impression that the DI guns would gunk up and cause problems after 500 rounds or so. Really wasn't wanting a gun I was going to have to tear down every time I shot it. Thanks for the info, I am planning on getting 2 guns I know I going DI but I might try and get a piston driven on down the road.

    Thanks sniper03, that sounds like it would work and will give it a go.

    You know I don't have any ideal what a SHTF will actually be and I hope it don't happen. I'm just trying to be prepared, I can see with my own eyes things are changing and it is not looking good. Just want to get this done before they outlaw firearms altogether.
