ORIGINAL: Triple Se7en
A better alternative (in my opinion) is the T/C Renegade or Hawkens. You can buy a slew of aftermarket drop-in barrels for either one& that's what sets them apart from most other manufacturer makes & models-- plus T/C's best ML warranty in the entire firearms business.
The same 15/16" GM IBS drop-in barrels that fit the T/C Hawken will fit the Cabelas/Investarms Hawken.
