Howdy, A friend tried to sell me a stag arms 5.56. I passed as the accuracy wasn't what I would want and the 5.56 round is fine for groundhogs. but not a caliber I'm interested in. But I was very taken with the AR platform, and seeing how I already reload and shoot .308 I started looking at .308 AR's. AM leaning towards a DPMS AP4, with a couple of questions. 1.Should I order the removable hanguard or the free float tube? I din't plan to hang any rails on it. 2. Will I be happy with the 16" barrel, I intend the rifle to be for defense, huntiing deer out to 300yds. 3. Will I see the front site with a 3x9 scope, or would I be better off ordering a model without the site. 4. Do I really need the foward assist and dust cover and shell deflector, or should I just go with the sportical for about $150 less. 5. Has DPMS solved any Mag issues they have, or should I buy mags from other vendors. Thanks for the help, looking foward ti buying this rifle.
