OK, so I'm originally an AK man. I lived to shoot them (among others) for years. I love to break them down, modify, accessorize and just make improvements in general to them that makes the more effective. The hardest thing to improve was (is) the accuracy. As we all know it is simply the Achillies heel of the AK-47 and there isn't much (outside of major modifications i.e. re-barreling) we can do to improve that. Now then. . . I'm thinking the same thing about the AR-15 in regards to reliability. I've had quite a bit of luck with them overall, however failures DO happen every time I go to the range. They are all easy fixes, but nevertheless it is something I'm not used to. Just as I was not used to being able to hit a 10" steel plate at 200 yds over and over with a 1x magnification optic. So I ask. . . What (if any) are some modifications and/or improvements that are available or you have used to improve the reliability of this rifle. Mags and Ammo are a Give In and Don't count here!!! I ordered a bolt enhancement kit from Bushmaster (only for my basic model BCGs) and know that the Bolt/carrier group is the heart of the AR and a good one is necessary for reliable function. So which one do you use? Do you see an advantage to using a chrome bolt in a standard carrier? Is the nickel boron the answer? Lets Talk!
