What is the difference between the arsenal slr107 and slr04 besides caliber?
I found a handguard that I really want to purchase. The description says
"Be sure to choose the correct thread type for your AK (Most Krink Types us 24mm)
- For SLR 107 Krink Types and SAM 7K-01, 04,44,UR, SFK, 104UR, 106UR users choose Mod1 mount Stamped Receiver or Mod 3 Mount Milled Receiver
-For SLR107 Krink Types and SAM 7K-01, 04,44,UR, SFK, 104UR, 106UR users choose SAM 7K Railed Gas Tube if you want to use our gas tube
-Krink Type users will have to remove HG retainer use use this Handguard"
