No problems at all with my Sport, 2000 reloads so far. Not sure why people refer to this as a 'starter AR', couldn't ask for anything more than it offers.
Well this what really should be the question. Chris I am not ragging on you or the Sportline... I have sold a bunch of them and recommended them to certain people.
It really comes down to what your personal needs are for the rifle, are you a causal weekend warrior that wants to enjoy the AR platform and plink around with friends and family? Or are you looking to have a nice SD/HD rifle, and plan on taking some carbine courses, or perhaps carbine competitions and 3gunning?
Those are just two examples of 1000's. You have to narrow it down by what your going to do with it, how often or how little you will fire it, and with mostly what type of ammo.
I get a discount on ammo... but somedays I still say screw it and fire off some cheap dirty steel cased ammo. Personally I want to know my AR will be able to eat it up ok. I often have range sessions that can reach 1k-2k rounds with my AR. I also use mine as a primary HD gun because I live in the country where the police response times are +/- 30 minutes.
I will say the Sportline is a solid entry AR, that will cover about 90% of the people looking for an AR. If you want to get into it hot and heavy, I would look at spending a little extra. Stag is a great entry level AR... but Colt, BCM, Spikes are probably better routes. With a little know how, and some youtube videos, you can grab a BCM upper, a stripped lower or your choice, and a lower parts kit and have a GREAT AR for about the price you would spend on the Stag.
