I bought an 870 about 4 years ago. It's been a fine shotgun. But since then, I've bought 3 new Marlins (which is now owned by Remington). All 3 have had problems and the service from Marlin has been terrible. Their idea of service is to tell me I'm asking for "free parts" and they don't give those out. So much for their warranty. I did get a call back from a supervisor telling me they would replace my parts. They have so far replaced one out of two. It took them nearly 5 months to get it to me. I don't know if I'll ever get the other part. It's coming up on 5 months too.
The first I shot was my fathers 1960's era 12ga wingmaster
(after that the only 870 for me was a wingmaster)
the next was my Grandfathers Model 10 12ga, it was ok but seemd to kick pretty good (?too much comb drop?)
then grandpas model 721 in 30-06 (I scoped it) very accurate.
Actual Remingtons I bought Myself.
A Model 700 BDL.............in 17 Rem!! what fun!! (traded it off but dont regret it)
Remington model 78 Sportsman in .223Rem (gave to my Dad as gift, He loves it!)
A box of parts that after $150 turned into a Remington Nylon 66 (wonderfully accurate) traded off because it was boring.(traded it off and now regret it)
after some trading I ended up with a model 572 .22 pump (very accurate) almost boring to shoot.(traded it off and now regret it)
Bought a early 80's era 870 wingmaster with after market 26" ribbed barrel with choke tubes.
I am now working on another project gun, nickel & dimeing together a model 552 semiauto that'd been left in a porch for years and forgotten about .(needs new wood) already bought used barrel, need useable trigger group (on salty sea coast).
Remingtons are, in my humble opinion, just as good as any other factory rifle out there. I bought one of the SPS Varmints in .308 a few years back and the thing was a good shooter out of the box. Adding a Bell&Carlson Medalist stock, lapping the lugs and adjusting the trigger made it a very good shooter, easily under .5", that is if I do my part.
