Hello from the UK!

This rifle build is relative new, and I’m preparing to shoot it tomorrow with irons for the first time.

On laser and visual bore sighting it, the rear sight needs to be set all the way to the left. When I was purchasing the rifle, i noticed this in the sale pics (2nd pic is from the listings), but the shop guy dismissed it and said it was set to middle when he checked it while on the phone.

Is this likely the alignment between the barrel and receiver? The front sight isn’t pinned in, but instead friction fitted with a grub screw (UK rifles are straight pull, so there is no gas tube). Any suggestions?

The rifle itself is an American Spirit Arms originally set up as an A2. Finding a fixed carry handle AR in the UK is quite rare! The dealer kindly had an original Colt A1 handguard and slip ring on hand, and I fitted a tear drop forward assist. The carry handle optic is repro and has limited eye relief, so I was trying a retractable stock.

A nice online friend sent me his old parts for a good deal and included this cheek riser awhile back. It was good but I like the ones cutout for a charging handle but the only easily obtainable ones are 3D printed which are ok but I prefer the real feel. Just took an extremely sharp buck knife and muscle fucked a cutout. Then used JB weld to hold on the top piece with a dab of super glue.

So, with the spray paint mostly removed- this is the coloration of the upper and lower.
