Had a shot a week ago with the new P7 on my SR556, glass is nice and clear reticule is even clearer. No issue with canted reticule that I got on the Vortex, just fitted it, torqued it up and it was perfectly set on the rail and was aligned with the target.
The eye relief acquired a focused reticule with fast target acquisition . This model is way better than the HD7, is just more versatile. For $799 from NZAR15.COM it was well worth the extra $100, it would compete with the Aimpoint models at the same price.
The red dot in the Aimpoint was too bright for me on the lowest setting, the P7's dot is really clear, the auto light sensor is really helpful so you don't have to fiddle with the brightness.
I will get some images up ASAP

Does it lock the bolt back when the mag is empty?
If so, then its getting enough gas, if not then it needs more.

Is the buffer spring got a bit of grease or oil on it, not to much but not as dry as a nun's nasty...

And what type of mag, a lot of the 5 round mag's are problematic in the way their springs are coiled and apply to much pressure on the cartridges, and that then causes similar issues you are facing...
A 10 round mag, with something limiting follower travel to 7 rnds is best for A-cat...

Just food for thought.

Yes bolt locks back on empty mag. The mags are one nylon 7 round of unknown origan and three of the latest generation spear 7 shot mags. Problaem seems to happen more on first shot than last shot which supports your theory.

Thanks for the input, any thoughts on how to fix the issue if it is mag related?

Try put an enhance magpul follower in them if they can fit, not sure if you can with the spear mags ones.

Any idea where I get one from? How will that change the spring pressure in the mag?

"Have I restricted the gas flow too much and it's short stroking" strikes me as this yes. My assumption is the bolt isnt going back far enough to get enough compression on the spring to get the energy to close, id give it a wee bit more gas?

My AR gets slower as it gets dirty and starts to get more suseptable to this issue after a few hundred rounds, a quick lube of the bcg and its fine again.

With the plastic spear mag I have I once was a bit to enthusiastic and managed to make it go in a bit far, gun sulked, never happens on a steel mag, so I wont buy another one.

I'm interested in this also..have you had a look through and ACOG before, how does it compare if you have?

Cheers

Are you sure the spring pressure is an issue? I've fixed many people's mag issues with these followers.

Finally fitted the A1 style black walnut front guard.

Very nice. Did you make that yourself Steven?

No its from the USA ironwood design I think it was. I am making a CNC so I'd like to be able to do stuff like this...
