I bought this rifle because the price point was right for me and I don't need a "race" nor "combat" AR15 with lots of rails, lights ect.
First off the fit & finish of the rifle is first rate. No play between the upper & lower receiver and the included hard case, sling, 30 round magazine and empty chamber plug were a bonus.
I mounted a Vortex Strikefire red-dot on the rail, no BUIS, and off to the range.
Off a sandbag rest at 50 Yd.'s to zero in and the first 10 shots were all over the place? 6"X6".
I forget to KEEP BOTH EYES OPEN, D'oah, as this was my first time shooting a red-dot sight.
The next 10 shots put me in the 9 ring and the next 10, adjusted further, resulted in a 3" group center mass, the best I can shoot.
Note: I was shooting .223 ammo not 5.56mm and the slight difference in chamber dimensions will make a difference in accuracy.
Importent note: Although the rifle comes well lubricated out of the box and following the pre-firing cleaning as required by the owners manual, I experenced a failure of the bolt to hold open after the last round was fired on 2 different magazines (50 rounds).
I was told by Windham tech support that one needs to "generously" coat the bolt carrier with gun grease, not gun oil, during the break-in as this part takes the most stress during the firing cycle.
Overall, if your looking for an entry level AR rifle this is, in my opinion, one of the best options out there.
