I've never been a big fan of the 742, but I have a friend who absolutely loves them, and owns several. Even he will say that reliability can be problematic if meticulous care is not taken. I am spoiled by the reliability of military-grade semiautos, and while the Remington is not a bad design it cannot come close to that level of reliability. They seem particularly sensitive to any magazine flaw.

Check the disconnector for wear. When the rifle will load a round into the chamber but not fire the disconnector is worn out. That part is no longer made by Remington. A disconnector for a 7400 Part NO F91431 can be cut and filed to fit the Rem 742 carbine semi auto rifle. But it takes a lot of fitting to fit it to the action bar which will also be worn. The Rem 742 must be kept clean and lubed. The new Rem 7400 rifle is a better rifle.

I shot about 150 rounds of 7.62 NATO (UK) through my 742. Occasional jamming occurred if I shot more than 30 rounds between routine chamber cleaning. But when I did my part, the Remington worked properly.

I sold it to my nephew in 2005 and he still hunts with it, trouble-free. I showed him how to use a bent toothbrush (with candle) to clean the chamber.

Remington's 742 is a KEEPER!

I know a buy who worked for Remington engineering and he told me about 1984 they were stopping production of it because of the problems and there would be no more parts. That made me sick because I had a 30.06 Carbine that shot 1 1/4" with handloads.

He also told me the projected life of them was 500 rounds and I now know why.

If you turn it over and watch the action of the bolt lugs as it opens you will see the only thing that stops the bolt from rotating further is that one set of locking lugs bangs on the rail. After awhile the banging will wear off that thin rail and bolt will rotate further around and jam city.

Buddy of mine had a chance on one for 50.00 and said it wasn't acting right. I showed him what the problem was and he said no problem. He TIG welded it and rebuilt the worn section and got it going! ! !! Then again how many have access to such a person.

Now the 760 is a different thing and although it cycles identically it holds up for years and years of hard shooting. I have seen them with the the rifling shot away for three inches down bore ! ! ! !

I have a 7615 and like it alot. Really accurate little gun with handloads I can put it in 3" at 300 yards.

Needs to have a trigger job on these, creep and heavy pull is standard. I reworked mine to a two stage trigger that is quite nice and sears up every time. If you compare a old 760/870/742 you will see the sear surfaces are completely different so basically I just made my 7615 look like the old one.

Never had any problem with factory mags but after market mags tend to be problematic. The steel one that Brownell's sells I understand is good.

On 742 you need to pull off forearm and clean the gas system. coat it with Mobil 1 oil 0W20-5W20 is what I use. It will keep the carbon soft and easy to clean. Best to clean it just as soon as it is fired as the carbon gets hard.

I had a Rem 742 in .30-06 as well. There was a recall on the ejection mechanism for some and mine was one of those. It'd load a round fine but it'd stovepipe the brass fairly often. It was fairly simple to fix, though. Other than that, I didn't have a problem with it, really. I treated it as a single shot until the recall came in and even got a few deer with a stovepiped brass after the shot, kind of like it was smoking a cigar afterwards

My uncle has had one in .308 that he's used for about 30 years now with zero problems at all. It's a good rifle.

I assume they replaced the ejector spring with a stronger one. Had not heard of that one. Come to think of it I never heard of a problem with 742 except the after market mags. I had one of the Colyer 8 shot mags and never got off 8 shots without a malfunction.

Using it as a single shot brings back a memory of a deer hunting club in Pennsylvania (I think it was) and their rules were they could only take one round to the woods with them so they knew they had to make it good. As I remember the article they had more kills and any other club around.

Last year I heard the figures was when I lived in PA and they said during deer week they killed 28,000 deer and 34,000 were killed on the roads that year. Just imagine how much good brass is laying about in the woods in PA never to be found ! ! ! ! haha.

It was a long time ago, but it was either the ejector or the extractor or something down in that area that had a problem. The thing was that not only was the occassional brass stovepiped but you could see some scratches/gouges down around the rim where it was like it couldn't get a good grip on the rim to pull it out of the barrel correctly. Anyway, it was something that was evidently pretty easy to fix. If you get a 742, I'd just recommend examining brasses to make sure they're in good shape after firing, particularly the rim to see if there are any scratches on it.

740 and 742 rifles can be converted to pump action and you’ll get many more years of use.

Welding and remachining the rails is an option but it has to be done carefully so that there’s no heat damage done. It would probably cost less to find a used 7400 and the problem will just recur on the 742.

Chamber pitting was a big problem with the Remingtons as they weren’t chrome lined. A pitted chamber will lead to extraction problems and worn extractors. Keep the chamber clean and corrosion free. A lightly pitted chamber can be polished out but not very often or it will become oversized.

The extractor is weak for a semi-auto but they’re easy to replace and inexpensive.

Do you have a link or web page that describes just how this is done.

While my '06 742 is accurate and reliable, I'd sure like to read the how to's.

It requires some machine work and replacement of some parts with 760 parts.

http://www.ahlmans.com/index.html

This is the outfit I used to send them to. They still list the service. I didn't bother doing it myself as the 742s always seemed to end up in my shop just before deer season when I was swamped. I haven't seen any descriptions of the process on the web.

I've had one since the early 70's and have shot it quite a bit. It has some battering of the bolt and receiver but it still functions. Never had a jam or problem. Now the negatives in my opinion: No Gunsmiths will work on them. Harder to clean and you have to clean the barrel from the muzzle. Parts may or may not be available. Low resale value because of all info that's been posted. Like in the post from a previous date given, check the receiver where the bolt stops at the back for battering. The receiver will have battering marks from the bolt. If it's obvious or excessive, don't buy at all. The headspace on the Rem or other semi-autos is most often near maximum and it will be harder on brass than a tighter headspaced bolt action.
I'd think about getting a good bolt action but again I've had good luck with mine and it shoots more accurately than often said about semi-auto's.

I bought a 742 in .308 cal in 1973 and used it for hunting deer for many years and it always shot perfectly.The groups were always between 1 to 1 1/2 inches with federal factory ammo.
Never any complaints.
I sold it to one of my best friends when I started to purchase my Ruger #1s.
He still uses it and swears by its performance.

I found the most common cause of inaccuracy in 742s was a loose barrel takedown nut. Tightening the nut usually took care of it. Sub 2 inch groups at 100 yards with good factory ammo were usual.

Here is the answer to cleaning from the muzzle to protect the crown. I have these on every cleaning rod I own.
http://www.superiorbarrels.com/Bore%...e%20Guides.htm

Use Mobil 1 synthetic oil on the gas system. Keeps the carbon soft.

The impact on back of receiver is not the problem that will shut you down. Look and feel where the bolt impacts on the rails right after it opens. That is what will shut you down as the bolt will turn and jam city is what you got.

I know this is an old thread but I have a question about the 742. I replaced the bolt in my 742. When firing afterward, the primer came out of the shell casing and stuck in the action. A friend says that I need to set the head spacing. How is this done on the 742?

The very first Remington model 742 rifles were excellent in operation. Then something went South with production (several problems happened) and those rifles were not worth their weight in salt.

I purchased a new one back in the early 70's and it had a bad barrel, wrong iron sights installed at the factory. Remington Rep stood me up once and then I just traded the rifle off on a Belgium Browning and never looked back.

In my area the gun dealers will NOT take one in on a trade even!!!

Most of them won't shoot very well, I have never seen one that shot well and I have shot a lot of them for folks..I am sure a few will, but so far nada!

On the other hand, and to my surprise, the pump versions that came out about the same time shoot like a house afire, fully the equal to bolt actions...They also rattle like a bb in a box car...The CIA purchased a number of them for assination rifles after doing some exhusting tests, and found them super accurate out of the box...Funny since they are not allowed to assinate, more of your tax dollars wasted.
