Rear sights: A1 vs A2

[scottryan]

Diemaco has the side wheel too... just from trying to set things up from those two photos, I'm not a fan but it's one of the defining pieces of a C7 or C8. This gun needs at least a Vortex Spitfire for combat use if not an Aimpoint PRO, I would NOT want to fight it with only these irons. That "BUIS in FRONT of optic" thing doesn't help either...

But, the girlfriend wants to learn 'the old fashioned way,' so... we'll let her have a go at it, then I'll smack on my plinker Bushnell TRS25 for getting started.

The Canadian plastic A1 rear sight mounts at the front of the upper in its storage position in front of a Elcan. It is not intended to be shot in this position.

Upon failure of the Elcan, the Elcan is removed from the gun, the plastic A1 rear sight is to be moved to the rear of the upper and used like any other standard open sight.

Thanks for adding that, Scott. Yet one more "WTF was Ottawa smoking?!" item... when tenths and hundredths count, back in the fight is seconds away, a forward optic and pop-up BUIS like most other countries woulda made more sense.

I've seen pics of Marines running M16A4s with ACOGs, with the detachable carry handles mounted upside down at the six-o'clock position on the handguard rails. I presumed this was so they were readily available to be mounted to the receiver as back up sights in the event the ACOG was rendered suddenly unusable in the field. I dunno how well they retain zero when removed and put back on but from what I've seen they seem to stay close enough to be at least usable in a jam. (I always re-zero mine after removing and re-mounting them regardless of whether they appear to need it or not though, but Im also obsessive compulsive about my zeroes)
Although maybe the Marines sticking the carry handles on their handguards was more due to some official policy that the carry handles had to be retained with the weapon vs an actual utilitarian purpose, I'm not sure.

If you put the carry handle back on with consistent thumb screw tension, it'll retain zero pretty well. Military shooting teams do this with carry handles on the regular. I've done it myself and kept zero fairly well at 400 yards and in.
