My brother, whose household was previously a gun-free zone as "the world is a kind and loving place," as they'd tell their son to believe, has purchased his first firearm to defend his home in these trying times.
He got a stock standard Remington 870 DM with wood furniture after a bit of steering from me, though I wasn't there physically at the time of purchase. Supposedly they had a magpul version with the pic rail and post sights but he didn't see the value added in the cost. Whilst I'm sure he'd be fine with the bead sight I'd like to get him pic rail and red dot for his upcoming birthday [around Mother's Day].
Is the top of the DM already drilled and tapped? Or would the side-saddled mount work or work better? Also would a SIG Romeo5 be about the cheapest I can go for shake awake and/or 5-digit battery hour life?
