I've been practicing bump firing lately. Has anyone on this forum ever experenced a slam fire??? If so what happened. And is it common. Thanks, any help would be great.

I guess thats good if nobody replies to this question. maybe slam fires are rare.

Slam fire is bad in an AR-15, if this is a normal occurancefor you, you should check your parts out!  This could be percieved as a MG if this can be done repeatably!

Silentweapon338, I have not had a slam fire. just wondering if it is possible or if the AR15 is pretty reliable for bump firing. which it sounds like it is. Thanks

Since there is no spring to hold back the firing pin, it is possible to slam-fire an AR.  However, this is pretty rare.  Keep the pin clean and use ammunition with decent primers, and you won't have any problems.

Lame duck....the bolt face hits home while the locking lugs are not engaged, and the carrier must complete it's rotation of the bolt as it makes the journey into battery. Only then can the firing pin reach the primer. The AR-15 is quite "soft" closing for a battle rifle, it would be quite a task to get it to slam fire.

Bumpfire is no good for an AR also. And yes...slamfire is next to impossible for a properly working AR-15.

Yes, it can and does happen.  I have never seen it happen when the rounds were fed through the magazine, nor have I seen it with rifle primers.  But I have seen it happen when using pistol primers and dropping the bolt home with a loaded round already chambered in the barrel.  Of course the locking lugs are fully engaged, so your gun is not going to come apart on you.

I have seen discussions and pictures of a slight dimple on the primer of a chambered round in an AR.
Presumably, if you repeatedly chambered the same round, you might make the primer more sensitive.  Or you might just damage the primer compound, so it won't fire at all.
Don't worry about it unless it starts to happen.
