cant say much about the bar, like them and have though of getting one in the next few years though, I recently purchased a remington 7400 carbine in .30-06 wood stocks, keep in mind the carbine, if you do buy it, will not be the glossy stocks that the full version can come in. The remington is more of a hunting rifle in my opinion, you can get 10rd clips pretty easily and have heard of people with large military clips from 'nam snipers but not to sure if youd be able to get one of these.. The 7400 and assumably the 750 as its almost identical to the first(they just made the 7400 only synthetic and 750 the wood version) works almost the same as the 7600, it has two bars that cycle rounds, gas driven half way up the barrel on the 7400. Im sure youll hear a million comments about constant jaming, i never have had this once, the older models had wear problems but thats after thousands of rounds and like i said the older versions, obviously, being a gas driven gun, it should be cleaned so residue does not clock the mechanism, the front end stock enclosing the diver rods is accesable by removing one flathead screw and slinding the stock of along the barrel, very simple and fast(cant mess it up). If properly cleaned there should be no reason to ever get jams. The gun itself is not to badly priced, i got mine completely new for $500 at a local gun store, if you cant get one that cheap print the price from wally world and ask around if anyone will meet that price(what i did ;P, i know im cheap) the gun comes with a 4 rnd magazine cleaning brush .. think that was it, extra factory magazines are everywhere for 20-25$ but if you go online you can find aftermarket ones for less... i own a rem 760 carbine from 40 or more years ago and you should know the wood wont stay as beautiful as it comes, i also own a 760 in gloss from 1976, that wood does look almost the same as when it came from the factory,
anyways that might be alot but just my thoughts...i could have gone on lol
the main difference in my opinion(not knowing if bars are reliable,sure they are) is price
the BAR might run 700-1000+
the 7400/750 will run you 500-575
Also the remington has the smother profile withought that 45 angle, you might like that, thats your opinion
if youre rich go with a BAR, if youre poor like me get a 7400 and save up a bit more money and get a rem 700 for longer range
thats what im doing
