We are not out to gouge people, gun prices in this country have risen enough and since we control the costs on stuff like this we like tp help you guys where we can. The increase in price will only be the difference in price it costs us to get them from the distributor compared to a standard 870 Express. Otherwise all the same process to turn them into our 8.5" & 10" guns is the same as we already do now so there will be no extra charge. I have ordered 5 from the distributor to build as samples. They tell me the ETA will be Jan/18 sometime. On a side note, we have actually changed a few things on out 870 barrels as well to update them a bit. I think you guys will be happy with them, updates to come as we get the process going and make a new batch of them.
