    i want to pick the brains of the ar guys.i don't want to turn the post into a bashing of brands,i want to make what i have better not buy a whole new rifle.1st issue my target (bench gun) is an Olympic (shoots great) i re-staked the gas key (as seen in the pic) did i do a good enough job? 2nd issue the Olympic bolt carrier is not chrome lined.should i buy a new carrier?or just not worry about it being its a bench gun.3rd issue on my 16 gun i bought an single point sling attachment plate(as pictured)i've seen several different types some have a long slot some have a round sling like mine my question is since mine is the round hole type is there a certain type sling i should buy?4th and final issue my 16 inch guns barrel is not chrome lined and i am wondering will it hold up in a shtf situation? if not would a chrome lined Daniel Defense barrel be a good replacement? thanks in advance[​IMG] guys![​IMG]

    Don't let the sling mounts on your gun determine the sling you are going to get. You can change that stuff out if you want. You have to get what works for you, the AR15 is so easy to change and swap out everything, why not?

    I would recommend a 2-Point Quick Adjust.

    hard to tell from the pics, but the rear screw looks well-staked; the front, not so much

    for the bench gun, i wouldn't waste a lot of money trying to make it more reliable as you'll likely be cleaning it often and can inspect if something is amiss. if i were spending money on it, it would be to accurize it, like putting in a krieger barrel or better glass or trigger, etc.

    for your 16" one, yeah, get the BCM or DD BCG and swap them out. save your oly for a backup.

    By "not chrome-lined" do you mean that the entire bolt-carrier is not chrome lined or that the interior recess where the bolt sits in the bolt-carrier is not chrome-lined?

    The first is no big deal and true of even the M16/M4 BCG. The second is a problem that needs to be corrected with a new bolt carrier group.

    2. I agree with Taliv's assessment of the staking job.

    3. I would buy whatever sling I want and then change the sling plate to match the sling; but it looks like that will work fine with snaphooks.

    4. Barrel lifespan is determined by a lot of different factors, so it is hard to say. How fast do you shoot? How much accuracy do you need? How many rounds do you expect to put downrange through a single barrel? Suppressed use?

    The second issue is extraction. A chrome-lined chamber should aid in extraction in a hot or dirty rifle. More importantly, budget, unlined AR barrels often have tight .223 chambers that can be a problem on their own, even before you consider the chrome lining.

    If I were in your shoes, I would probably do one of two things.

    1. If money is tight, hit the barrel with a 5.56mm chamber reamer and repolish the chamber to insure reliable function.

    2. Sell the old barrel and use it to finance a new, better barrel from someone like BCM, Noveske, etc.

    However, before I did any of those things, the first thing I would ask myself is "Have I shot any of these enough to break them?" If the answer is no, my next question would be "Do I plan to do any kind of shooting in the future that is significantly above my current levels of shooting (training classes, zombie-killing expeditions, 3-gun, etc.)?" If the answer to both questions is no, then I wouldn't worry about it too much.

    Olympic uses their own hardening process instead of chrome lining the bolt carrier. My K3b has a few thousand rounds through it and it is working fine with no visible wear. It is also my smoothest working AR. I would not worry about it.

    thanks allot for the input guys,this is what i've decided to do:i'm going to leave the bench gun alone(oylmpic) my 16inch gun is going to get a bcm barrel and bolt or daniel defense (depends on sales and what not when i get ready to buy)the reason i'm just going to leave the olympic alone is when i go to the range it might get 20 rds through it. but my m4gery might get 150rds each range trip + its my shtf gun so i think it needs to be upgraded

    I think that is a smart choice.

    If you want to improve the bolt carrier, you might want to consider micro slick from Amelon Coatings.

    Chroming is milspec for full auto corrosion prevention only. It's a heat thing. Unless your dumping multiple magazines at the rate of 2-3000 rounds a week, keep what you have and shoot it. When it does become a problem, then upgrade.

    There are a lot of posters on forums concerned with absolute reliability in SHTF situations, a reliable firearm is important should such a rare and singular occasion arise. BUT most of these are well documented in police reports, usually involve handguns, and less than three shots are fired.

    OMG full auto the zombies are coming, no. Not even during Katrina, and that was definitely a SHTF situation.
