So, while browsing for what I thought would be a new 9mm carbine range toy, I ended up purchasing an ATI Omni Maxx Ar-15 pistol instead. With the price south of $400, I couldn't resist and before I knew it it was in my virtual cart and then ordered.....So, rather than the well thought out and pre-pondered purchases I usually make, I totally bought this on a whim....Did I make a mistake? Reviews all seem pretty good from what Ive seen. Anything I should know about in general about AR pistols? Plans are to basically leave it alone after addding a shockwave brace and a Bushnell TRS-25. Should have the gun and all components by next weekend.
