AR questions

sell33 · 02-18-2008, 09:48 PM

Ok, i am very interested in getting ahold of an AR. I would like to get something bigger than the 223 so it is a little more versatile even if a little more to shoot. I have been looking at the DPMS 260, and also some 308s. I would kind of like to build my own if possible, and it will probably not be for a little while seeing as my budget is small at the moment. i know you can buy all different brands of uppers and lowers, stripped, full, etc. Honestly i dont know enough to know what would be a good combo. I love the platform though and know that i will own one eventually, hopefully soon. If i want to hunt mostly varmint, but possible throw in deer if (when) i get the chance, what caliber would u suggest? i would rather not have HUGE exit wounds on varmints. Also, are all uppers and lowers interchangeable? If not...which are? thanks for all the help!!

The 6.8spc is getting popular. I'm looking for a upper in 6.8 now.

Congratulations on choosing an AR shooting platform>I am not highly experienced in AR,s but know a little about bullets and treir effect on varmints.To keep from blowing big holes in varmints you have two choices,a very fast light bullet that expands very rapidly,expending all of its energy inside the animal without exiting,or a larger,lower velocity bullet that can pass through with no upset,thus leaving a small wound channel with little hydrostatic effect.The first is easy to achive by using high velocity small caliber bullets that virtually disentigrate on contact with minimal contact with the slightest resistance.This works with coyote size animals but when you get to fox size animals you need to go to heavy slow bullets with low energy that will pass through without expanding.It will be hard to ubderstand but a 100gr bullet in 6mm will do minimal damage to pelts due to minimum energy release.Heavy big game bullets in larger caliber are the same way.If you are going for larger caliber bullets,you will have to put up with low velocity and poor trajectory.This usually means shorter ranges.The whole problem is a thin skinned animal like rabbits and such just blow apart very easily from hydrostatic effect.The way to go is a small diameter,light bullet at high velocity that blows up before it can penetrate very deep. sam.

Thanks sam, i understand the concept for the most part im just wondering how to go about beginning the setup, can i get any standard AR lower or are they not all compatible?

Others are way more qualified to answer that than I,and I have confidence they will.Good luck. sam.

You may want to check out Stag Arms while you're at it. They have 6.8 and .223 in left hand and right hand. They have a bull barrel varminter too. Good luck with your decision.
