I have not handled one in the flesh butthe Savage features appear to be limited to the barrel nut and, to a certain extent, the separate bolt head. I say, to a certain extent because the Marlin rifle appears to lack the gas baffle found on the Savage. I like separate bolt heads though. It is the only thing I like on the A-Bolt! I think they are a good way to produce a bolt which is straight and they offer the possibility of changing between cartridge groups in the same action.
The striker and trigger system look to be quite conventional while the Savage is unique.
The receiver is round (like a Savage) and appears to utilize a thicker recoil lug than the Savage.
The extraction cam seems to be machined into the receiver which is, once again, the conventional approach. Savage uses a separate piece to provide a cam for primary extraction.
The rifle looks like it may have potential and has some good features but I think we have to ask; Does the world need another cheap, plastic stocked, hunting rifle? I don't think so but Marlin must. Regards, Bill.
