I have owned two 7400 firearms, a full size .308 and the presently owned .30-06 Carbine Synthetic. Both have plastic dust covers by the bolt that cracked within the first box of ammo. Neither was replaced and both guns function fine. Both were surprisingly accurate with scopes attached. Neither had factory sights that wanted to stay on the rifle; this being of no significance as these rifles do not work at all for me with iron sights. Something in the stock configuration results in my having to crawl and hunt around the stock to get a good peep or open sight picture. Yet, with a scope, the rifles point quickly and accurately for me. The following comments apply to the Synthetic Carbine after having it for a year and shooting it on the range (about 250 rounds or so) as well as using it this year for deer hunting.
The bad:
1] The bluing or whatever finish Remington applied rusts with very little provocation in rainy weather. It is not a deep rust and after two days I rubbed the rust off with an eraser and applied gun oil, and where there was rust the gun is now wearing a regular shiny, smooth blued finish. This is especially evident on the barrel.
2] Reloads have to be tried to make sure the cases will function properly in the rifle. Even then, on occasion, one that functioned in a manual cycling test acts peculiarly during live firing. No problem with any Remington (only factory brand I've used) factory loads in the rifle.
3] I cannot dissemble my rifle as the forend screw as installed by the factory has resisted any attempts to remove it. I have a screw driver that is ground to fit this exactly and no amount of force releases the screw from its hole.
4] The trigger mechanism housing is plastic and fits loosely in the receiver.
The good:
1] This rifle is very accurate (around 1 MOA), even with its lousy trigger pull.
2] The rifle has functioned flawlessly with factory ammo.
3] The rifle points like a shotgun for me when it is scoped.
4] The rifle has pretty decent carrying properties for still hunting. I never sling a rifle in the woods, always carrying it while afield; and this rifle is balanced fairly well, has nice dimensions with the scope attached and is not too heavy. This results in it not being burdensome to carry and coming to shoulder quickly.
5] It cost $310 + tax new from the retailer.
The ugly:
This is one ugly rifle. No pride of ownership here.
Summary
a] The above good points allowed me to snap shoot a leaping doe in mid-jump at 30 feet with no problem.
b] I would not take this rifle on any hunt that was remote where an expensive hunt could get ruined by a malfunction. I simply do not see that kind of quality in the rifle that results in confidence of field service without malfunction required for such a hunt.
c] This rifle is great for the LOCAL (1 1/2 hrs from my front door) short range, heavy brush cover hunting I used it for with a 2 1/2x shotgun scope attached via Weaver rings and bases.
