Recently inherited an unfired preban colt match hbar A2. Was considering doing some tactical upgrades. From what I've been reading people are more into the newer design with no or a removable handle, i'm sure its much better for optics. My question, has the A2 become obsolete? Would i be better of looking for a newer design with the 16" barrel,no handle, and extendable stock if i am looking to add optics, foregrip, and other accesories or should i stick with the A2? New to the world of the AR so any help, advice, or links are greatly appreciated.
