I have a like new (less than one tin) .25 700mm STX barrel that I bought for shooting the 33.95gr, but I think I prefer length of the 600 and the velocity 25gr... I am interested in trading your .25 (low mileage) 600mm STX barrel and 100$ (negotiable) gets you my 700mm barrel... no probe, no mag, and no ldc, just the barrel and shroud, we each pay shipping costs PayPal F&F or add 3%
