Does anyone know where I can get a dry fire cartridge for my AR?

If you're just interested in dry firing you don't need anything at all. The rifle can be safely dry fired all day long.

Here or here.

These are the two places I could find quickly.  I am sure there are a lot more.  You may want to try your local gun stores as well.

I was afraid it would damage the firing pin......

Dry fire in AR=OK.

isn't it the bolt catch that gets damaged? never had that problem, but have seen it posted and responded to several times...Magpul has the best deal if you can find them in stock - 5 for $5, i think - everyone else sells the snap caps, 2 for $11 or something.  A poster said he made his own - brass case with a bullet loaded, no charge, though.  That would be less expensive, but you might want to paint it a different color.

The bolt catch issue is only if you're dry firing without the upper attached.

Damage can occur to the bolt catch, only if the hammer is released with the upper and lower separated.

Dry firing an assembled weapon is fine.

That's if you dry fired a lower with no upper attached.  The hammer flies forward unrestrained and can hit the catch.  If you have an upper on with a BCG, the hammer doesn't get that far forward.

Like someone once posted here years back....

Yes!  Dry firing is bad for your AR, but live firing is even worse.

The Marine Corps puts it's recruits through a snapping in session lasting an entire week before hitting the KD rifle range.  10 hour days of constant dry firing and the rifle functioned fine.
