SOLD Remington 870 Express Synthetic 7-Round 20 ga Shotgun LNIB 18-1/2' barrel $400 WAYNO. Oregon City. These 20 ga hi-capacity, short barreled Remingtons are pretty tough to find thru normal retail sources. This gun is a bargain but remains unsold. In a home situation, or for recoil sensitive shooters, the 20 ga makes a lot of sense. And 20 ga ammo is far cheaper and much more available than .410.
