Our Olympic AR had a very good trigger, but we felt the rest of the gun was average and overpriced.

Granted, the pistol grip on our Olympic Arms AR-15 was the same component used on the Smith & Wesson, but in this case the seams were left rough and unfinished. But we still like the swing away trigger guard for increased access when wearing gloves, for example. If you are wondering how a gloved hand is supposed to compress a spring- loaded detent pin, use the tip of a bullet.
We thought the gas block/front sight unit with hinged sling loop was out of place on a $1250 AR- 15. Testers said they thought the components had a surplus feel.
The removable carry handle offered two apertures adjustable for windage and elevation. You could put a scope mount in the handle recess. We’d prefer a smaller rear sight unit that left enough room to place a dot scope on the receiver between the front and rear sights.
