Not exactly a swap, more like just getting it to someone who can use it. I have a new in package Roy Rhodes extended, non ported, 12 gauge .650" choke tube for standard Browning Invector, win-choke, Mossberg 500 and 9200, H&R, weatherby and SKB systems (off the packaging). Choke has a knurled end, so no wrench required. Choke is available for the cost of shipping, $7.75, using a small flat rate usps priority box.
