That’s the variation I really want.  Or should I just get an AR kit?  Anyone know of any inbound?

Have you checked with Numrichs? They had some in stock not long ago.

A lot of the kits advertised as AR are actually ARM. At least the last two that I bought were.

That's good to know, where did you obtain them?  I am assuming no bipods but they had the provisions for them?

This my experience as well!

You're looking for ATI #ATIRKTGALARP.
They are around, not as abundant as the SAR kits right now.

If you get a SAR kit, you just need a different gas block, gas tube, hand guard, and hand guard retainer to get a AR/ARM kit.
Personally I like the SAR handguard & retainer way better than the AR/ARM (especially if you're not going to do the bipod).

Everything else is the same as the SAR kit, except the flash hider style (and again, the SAR flash hiders I like better anyways).
