PAPOOSE! there is no equal which has the combonation of low weight, accuracy, reliability, compact takedown, high rate of fire, and overall quality that the papoose offers.
the carry case is also handy in that it gives you a place to store other stuff like a cleaning kit and bullets. the buttplate can also be easily modified to house extra magazines. and while in the case the whole lot floats.
I'm waiting for a good used one to pop up in the EE that isn't $450. Someday i'll break down and get one new, but honestly im in no rush, my mod 60 is my survival gun as i personally have no real need for a takedown feature. Im of the mindset that it's no good to me folded up in my pack. but then again i drive a pickup, not a motorbike.
