Got nothing to do with hate for them. Its just practicality. 2500-2800$ for an ar15 is a little outrageous.
I would suggest the op go find one and see how he likes the feel. I find them clunky and unbalanced with all the controls slightly off.
Despite interweb myths the military still has not adopted them. A while back the military may have acquired a few and put them in the handsof soldiers for evaluation but thats always been part of the testing the military does with lots of gear. See how durable it is in the hands of soldiers capable of breaking anvils.
I think there are better more durable more reliable more accurate rifles that do the same thing for less.
You can swap out every part on a ar15 with a torque wrench or a punch to suit your needs. Dont like the stock or fore grip on the scar after you buy it?? sorry your stuck with it. Dont like the non reciprocating charging system after all sorry your stuck with it.
About all the adaptability the scar has is changing the color with spray paint.
If you want one go for it. Sounds to me you already made your decision before you posted. When you get one give us some feed back
everyone has different tastes and opinions thats what makes forums fun.
