Fully understand the reluctance re stripping a new gun that's under warranty.
Try a wanted ad in the wanted section. Keep an eye on the sales section. It might also be worth ringing around shops that are within easy striking distance and asking them to let you know of any incoming part exchanges so you might grab one before it goes on general display. Occasionally in the past I have managed to buy "display" or "demonstrator" rifles that seem unused / barely used and unmarked at a decent saving from new. It might be worth asking for those, too.
