over price, for nothing. I love my 220f and would put it up to a custom made Tar-Hunt. As far as a 870 Tar-Hunt, friend did just that with his 870 spent a good coin for the work, it was sighted in with Lightfields, at the time I used a 1187 rifled/cantilever barrel with the same ammo no upgrades I would out shoot him everytime....He wasted his money
