I'm in the market for an AR-10 (.308/7.62x51) type of friend. I've decided on the DPMS LR-308 series. This will be mostly for fun, SD/SHTF, and very, very occasional hunting (if I'm forced to use this for hunting, otherwise I'll get a .30-06 for hunting). I'm really liking the LR-308C (classic A2/A3 styling, iron sights) but I'm hesitating due to the barrel length and weight (11lbs). Knowing what its use is going to be for I'm looking for opinoins on the 20" vs 16" models, advantages/disadvantages. I know the 16" will be about 3lbs lighter and a little easier to swing (won't be used in the house, I have another friend for that...) but I've also read you lose some accuracy with the 16" length (at best I might take a 300yd shot). I believe most testing is done with the 20" length but I could be wrong. Just wondering what everyone thinks on this. While I appreciate all input please save some time and don't discuss the 5.56 (.223) option - it's not. I want a larger round; more punch downrange, etc, etc. I figure if I have to put lead downrange I want something that will make a little bit of a statement. I hope to God I never have to, but if I do.... I'm also considering 150g FMJ and soft point rounds - thoughts on the 150g? Too small? Just right? (Remember, not hunting if I can avoid it - punching holes in paper and zombies) Thanks for any input!
