It is a shame Airgunaid didn't make more of the completely new guts fitted to the SP5. As far as I remember, it came out and everyone assumed it was 'just' a G80 with a lube job and a .20 barrel fitted. Rod Lynton's article didn't seem to mention the extensive internal work and when we saw the power at 10.5 everyone lost interest. It HAD to be 11.9 in those days for a 'top gun'.
Look forward to the article.
