Generation 2 guns are any ones more recently made purely by Kodiak after their split from Wolverine. They should all have the threaded charging handle, and many suppliers are optioning them with replacement quality stocks and handgrips. Likely any reference to Wolverine has been removed from the chassis. Other then that, no one has mentioned other changes in this thread. Perhaps some one with a pre and post divorce version could do some side by side pics?
I guess I would say the "Gen 2" changes mostly focus on:
- The bolt carrier of which the metallurgy was altered
- The cocking handle which was changed from a push in variant to the threaded variant
- Most recently the new bread slice which holds the guide rods and recoil springs
It's my opinion that out of the two factory original cocking handles the first was more reliable as it didn't break off. It did however shave off some of the inside of the receiver to no functional impact, however people didn't like it so they switched to the screw in type. People don't like that either as it breaks and now SpectreBallistics has produced a newer variant (time will tell if this is a worthy successor)
If I had to make a perfect for me variant it would come out of the box with:
- A functional non-breaking cocking handle and piston (lol)
- A trigger of circa 2-3kg
- An ambidextrous magazine release
- A bolt hold open/release catch
- A rear retaining pin (I think too much stress gets put on the front retaining pin by itself)
- An easy to remove handguard to allow for easier cleaning of the gas parts
- Easier to remove gas parts, the gas cup is a beast to get out sometimes
