So I ordered my SSG24 on Feb 17th and it arrived Mid May.    It has the M140 spring installed which is advertised as 490fps.    Brand new, never been skirmished or had a B.B. chambered or magazine loaded.   this is the current model and the same one being shipped at the moment.    Located in Tamworth so the midlands and I’d rather cash/collection but postage could be arranged at buyers cost.    Think ive included everything, if you have any quest
