Sorry if I sound a little uninformed but could someone explain the j lock I've seen discussed on remingtons.

What does it do ?
Does it affect the function or reliability of the fire arm ?
Is it good bad or ugly

Thanks
 
The beancounters at Remington had Remington engineers design a new integral safety lock for the entire Remington line using a cheap, sheet metal "key" that was shaped like the letter "J". On the Remington 700 line, this new "safety device' was installed in the bolt shroud. In the shotgun lines it was installed in the trigger guards where the old push button safety went. The problem was the hole left for the key allowed all kinds of foreign matter to enter the firearm. It was possible for the "safety" to be partially engaged by foreign objects while beating through the woods and if you ever lost/forgot the "key" you were basically left with an inoperable firearm until you could obtain a replacement. While a life-long fan of Remington, I refused to purchase another Remington product while they were actively plugging this new "advance."

Complaints, letters of protest and drops in sales across the board finally forced the powers that be that maybe Lawyers weren't the best guys to be designing "safety" devices for their firearms. The "J"-Lock was abandoned a couple of years ago and good riddance! Aftermarket safety buttons and bolt shrouds can be purchased to replace the necessary parts on any firearms blighted with that abortion we now know as the J-Lock.
 
Do they still have the j lock on the Remingtons? I picked up an 870 express a month ago from SIR and it had no j lock. Never mind, what he said ^^^^^^^

I posted a pic of a firingpin assembly I just exchanged from a j lock to a normal one. The j lock bolt shroud is longer and the spring is coiled up. The whole thing is heavier and the spring being slinky like that apparently has a negative effect as to how consistant your firing pin strikes. The thread was moved to the Off Topic forum and the picture is under "Brownells service".
 
Curious about the J lock on shotguns. As stated the device is behind the trigger. Does this thing have any negative affects o the function of an 870 for instance ?

Can one just turn it to allow the gun to function and leave it alone or do you have to mess with it every time ?
 
I only ever used it once, left it on when I locked up my guns before going on vacation. You never need to touch it, but if it got gunk in it, I could see it could be problematic. Hasn't happened to me, but I've only had it out a few times.
 
Never heard of it before but I can just imagine the number of pissed off people that this created and how many customers they lost.

As was stated - Lawyers are not the ones that should be designing guns!!!
 
I bought an 870 express magnum a couple years ago, and it has the j-lock. Basically you just stick the j-shaped metal into the lock until it clicks into place, and you can turn the safety a quarter turn or so. When locked, it locks the safety in the safe position, and it cannot be moved to 'fire' without first turning the safety with the j-key. Once unlocked, the firearm operates exactly the same as any with a cross-bolt style safety. For me, it was a novelty when I first got the gun, but I have since stopped using it. I have the j-key handy in my ammo can, but that's about it.

The SPS varmint I just bought didn't have this abomination attached to it, and I thank the lucky stars for that. On the shotgun, it's rather unobtrusive, and doesn't really bother me by it's presence. On the bolt rifles, it's right in your face however, and I never did like the look of having it stuck on the bolt like that. And seeing Tod's pic of that stainless rifle ruined by that black 'pimple'... :puke:

What a shame...

I did that also; bought a new bolt shroud and firing assembly from Brownells. You get rid of the J-Lock but the new firing pin is a lot better also, because it it bigger diameter and the spring fits way better on it, then the stock Remington spring.
