Question: will this work on a 16 inch barrel or do I have to order the M4 model
Document: Worth the money. You get what you pay for. This is a top of the line optic.If its good enough for the Marine Corps, then it will work just fine a for a weekend shooter.
the only thing not to like about these optics are the price, but you absolutly get what you pay for. with in 5 shots i was shooting a three inch group at 100 yards dialed it in with 10 more shots and now i almost hit the same hole every time. VERY VERY clear feild of view and works great with both eyes open style shooting. if you are thinkin about this sight and havent decided yet, just get it it really is that good.
with the factory mount, it sits low on the flat-top. i would suggest to get a larue quick-detach acog mount and the 5/8 inch riser to get the optic up to a good shooting level. i bought the larue RCO mount and with the riser, the acog sits just where it needs to be to clear my rear iron sight and allow me to have proper head and cheek alignment to get the full field-of-view through the optic.
i have one of these mounted on my stag model 8.  overall, the best optic i have ever used. the BAC (bindon aiming concept) takes a little getting used to. basically, it is a "both eyes open" shooting concept in which at close distances, you do not notice the magnification of the optic and the reticle is seen on the close range targets.
at close range, with-in 50 yards, the aimpoint comp m3 sight is faster but at distance over 50 yards, the acog cannot be beat. the optic is callibrated to the 5.56 cartridge and the reticle has bullet drop compensators out to 800 meters. in order to properly use this feature, you must do a proper 100 meter "zero".
I choose the 4 star rating because the scope is well designed, manufactured, and does what it is intended to do.
I haven't used the scope but I have tested it off the rifle. Product is as described and appears to be of excellent quality.
One of the best optics I have ever used. Lives up to all other reviews. Would highly recommend - case closed.
I have been wanting one for a long time.Better price than I could find in a brick and mortar store.
I have have wanted an agog for the past 5 years and it is well worth the wait. My son is in the Army and helped my to pick it out and I love it.
