Peter, I concede to your superior knowledge of the SA80 A2 as my limited experience was with the original model back in the '80's (although I still struggle with the concept of tension springs in firearms!). Yes, I regret not being able to catch up with you at Warminster. Colonel K waxes lyrical about his trips there with you!
Bruce, the AMT was another of the rifles that saw service in the' deer wars' and I made up scope mounts for a few of them, but strictly functional with no thought given to retaining originality. The chopper boys were only interested in getting job done solidly and quickly so they could get back into the money!
MrClark, I have attached some photos of my L1A1 I took this morning.
