Although it's very cool, I tend to agree that a few enhancements would make it a lot better - here's how I would have designed it:
-18" bbl instead of 16"
-7mm-08 instead of .308
-Some sort of standard mag - M14, FAL, or HK91
-Oversized bolt handle & Winter trigger guard, yup.
-Stripper clip guide I could take or leave, but why the heck not?
-Fixed/integral pistol grip attached to stock.
Other than that, I really like it. I have a poor-man's version of this - No. 6 JC replica with scout mount.
I read the following on another forum and it makes sense to me why they went with the magazine they did:
A) they could not get a double stack magazine to feed reliably with their current bolt design.
B) Their are alot of M14/FAL/HK91 mags out there ranging from very good to very bad. They did not want people buying the gun and blaming the problems they were having on the gun when in reality it was due to crappy 3rd party magazines they were using, then constantly sending the guns back to the factory when nothing was wrong with them. This is something that had plagued their mini-14 lineup for a long time.
