My only complaint with the gun is the trigger.
I had the trigger cleaned up and now it's about 4 pounds with no creep or grit to it. Why would you pull apart a brand new rifle before even shooting it? I've shot nothing but handloads thru my 750 308carbine since I bought it and it has done nothing but go bang. Too bad, they used to be the industry standard. I will be very cautious about Remington in the future. It also soured me on Remington in general, that gun should have never left the factory in that condition, much less left it four times for repair and still didn't function properly. I really wanted to like that rifle, but I won't have an unreliable gun. On the fourth trip there the factory said there was nothing wrong with the gun, it must be something that I was doing.I have a friend who owns a gunshop and we spent an afternoon trying different magazine latches and different magazines in it, and finally came up with a combo where it would shoot reliably. It was absolutely the worst customer service I have ever seen. Long story short, the gun went back to the Remington factory four times over the next year, and was never repaired correctly. It acted as though the magazine was too high up into the reciever. Basically this was the problem-with 4 rounds loaded in the magazine and one in the chamber, first shot-good,second shot-good,-third shot, the bolt has slammed into the side of the cartridge,denting it. If I remember right I had 5 different factory 150-165-and 180 loads. Before I ever shot it I disassembled the major components, degreased everything, and lightly lubed it all with g-96, and reassembled. I lived the looks and feel of the rifle, it pointed naturally and came to the shoulder quick. That year I settled on the 750 carbine-thats where the trouble started.
I usually only buy one new rifle a year, so a lot of research and thought goes into it. 308 and it was the single worst experience buying a firearm in my life. They didn't really change all that much.About three years ago I bought a 750 carbine in. We lowered the drop at the comb so that you can use the rifle sights easily. Since the gas system is greatly improved, we can now use the R3 pad, and not have to worry about functionality. This allows the bolt to move and cam into place more freely. We have added a nickel/Teflon coating to the bolt head. This, again, translates into better reliability. By casting, we can better control internal geometries, and eliminate machining burrs. The barrel extension is now made as a cast part instead of a machined part. This will greatly increase reliability by giving more consistent bolt velocities, as well as allow us to offer carbine models in calibers not possible in the 7400. Moving the gas hole back we can capture the gases sooner, and under greater pressure. The gasblock on the barrel has been moved rearward and therefore the gas orifice hole has been moved rearward. The copper shavings in the gas port of the 7400 would build up over time, and cause the gun to not cycle reliably.
This does 2 things it eliminates the 90 degree turn at the gas port, and it eliminates shaving off copper in the bore from the projectile. In the 750, the gas orifice hole is drilled at a 45 degree angle, instead of a 90 degree like the 740/742/7400. "What are the differences between the 750 and the 7400?
