NEF Pardner Pump choke system?

[Tail Feathers]

I'm considering an H&R (NEF) Pardner 20 gauge pump for my grandson to hunt with this spring.
My search here showed it uses the Winchoke system?  But somewhere else I read it used Mossberg chokes. 
What chokes DO they use and does anyone here have a good setup to recommend?

They use thewinchoke system

 BROWNING, WIN, MOSS 500/9200, H&R, WEATHERBY, SKB
are the same in 20 gauge.

My mother recently gave me my stepfather's Winchester 1400 20ga auto,it uses the winchoke choke tube system,same as the Mossbergs.
I bought 2 choke tubes made by Carlson in the winchoke system,they are very good choke tubes.

Thanks guys.  Went to the gun shop to look and I may be buying a CVA 20 gauge single shot pretty soon.  That puppy was pretty sweet and I like the single shot for the boy.
