I've had this sucker in for a while and finished up my review; here are my thoughts....

Pros:
-100% reliable to date
-solid trigger for a military rifle
-decent accuracy with various loads (seen in video)
-CHF, CL pencil profile barrel
-takes all AR mags that I know of
-standard and 'adverse conditions' gas setting
-aftermarket parts are becoming available
-fit and finish are VERY nice

Cons:
-front heavy
-charging handle location may cause you to bang your hand up when charging it
-no bolt release
-Cost
