Hairline Crack - Cause of Concern?

Hi Folks,

Just noticed two hairline cracks on Remington 1100 (inertia semi-auto). One is in the receiver and the other is on the action bar sleeve. Are these a cause for concern?

Any and all opinions are appreciated.

That one in the receiver would be a truly bizarre crack path. Starting and stopping remote from any edge, geometry change or stress riser, zig-zagging back and forth without branching. No crack I've ever looked at has had a morphology like this. I'm guessing it's nothing more than a shallow scratch.

If I'm looking at the right thing, it's that 2mm zig-zag right in the corner of the machined slot? Unless it's bigger than what I can see it could probably last a long time. It looks like the material behind it just gets wider, so the stress probably spreads out and growth in that direction becomes unlikely. If it's small and you are concerned about growth you could probably blend it out with a round file and try to leave the corner smoothly radiused, but honestly I would be tempted to leave it alone.

The crack in the receiver looks (to me) like a cold shut, I dunno if Remington forges or casts receivers (or machines from stock) but that looks improperly forged or cast/contaminated during the process.
If it is a cold shut - it will become a crack... You can "feel" it with a dental pick (or something sharp)? Post it in a knife makers forum and see what they have to say.

Though just googled "Remington 1100 cracked receiver" - seems a common enough issue and also that it is a cast & machined receiver.

If it were me, I would not be shooting that gun.
 
Rem 1100 receivers are machined from a block of steel but a cracked receiver and action bar are not all that uncommon . Most likely magnum loads and a weak recoil spring or a magnum barrel on a 2 3/4 receiver with mag lead loads caused the problem over time. The 1100 is a gas operated action not inertia system as OP stated. If it is cracked it is toast IMHO.

I would replace the recoil spring and would be unconcerned otherwise. The receiver "crack" is a non-issue.
 
The only 1100 receivers I have seen with a crack, the crack has been at the end of the slot where the operating handle moves to on recoil...

I don't see anything in these pictures that would stop me from shooting this gun. Shoot away and keep watch... it's not like it is going to suddenly disintegrate. The breech bolt locks up within the barrel and that is where the pressure is...

That reminds me when someone would come into my auto repair shop with a fuel leak or a rusted leaky brake line and ask me if it was safe to drive I would say no but their reply always was but I will drive slow and take it easy.

I owned an early 1970 production 20gauge lightweight that cracked over the top of the frame. Remington made a change with LW20 with the frame and barrel. They replaced the gun under warranty.

You probably have more experience than Guntech and I with Remington 1100's. They were pretty uncommon on the prairies. ;)
