Is it ok to dry fire an AR with the upper on? Just got me upper in and it seems as though the hammer would be always cocked unless fired. Have always been taught to not leave a fiearm in this position. So is is safe to dry fire or would the constant pressure on the hammer spring have any adverse effects on it?
Thanks

Dry firing will not hurt your rifle as long as you have a upper receiver attached.

when i was in the corps we spent hours and hours "snapping in". this was an eternity of dry firing the weapon with a dime resting on the front sight post, the idea was to be able to squeeze the trigger slow and steady w/o making the dime fall. the military seems to think it's o.k to dry fire
just my .02 worth

...WITH A BOLT CARRIER.

IF you don't have a bolt carrier in said upper, you will still ding up the front of the fire control pocket. Nothing major, but looks like hell.

And yes, if you have a complete rifle, dry fire away.

And Leaving the hammer cocked will do NO harm to the spring. actually, dropping the hammer every time you put it away will wear the spring out.

Quality springs do not have memory, i.e. if you leave them compressed will not tend for them to stay compressed. The only thing that will wear a spring out is cycling it from compressed to uncompressed. Basically normal use.

with complete upper is fine.

And what about this? http://www.fulton-armory.com/DryFireDevice.htm
Not only would this absorb any shock, it negates the need to fully charge the weapon each time. I would put $5.00 down for one at a gun show, no doubt.

dry firing an ar has never given me an issue that i could see, just the same i use a snap cap often. i do dry fire or use the caps when going into storage, but i use them just as often for practice. pretty handy unit and they cost a few bucks.

I keep snap caps on hand for dry firing and to check for feeding and ejection problems. I've never seen that little Dry Fire Device before though. Pretty clever little item.
