I would be nice to see someone build one up with a higher quality barrel, and maybe with a slightly stiffer profile. KT is cheap, so there is no way this is a 'nice' barrel, and at least on my gun, the crown is nothing impressive; there's gonna be a floor on the accuracy figures just from that. Put a nicer barrel with match chamber and a little less whip in there, and I'd love to see how much things change.
1) Bolt is similar enough in theory to an AR that this can't be realistically impacting accuracy, assuming it's decently square (and it is, since we've seen no reports of broken bolts)
2) Due to the long cycle distance, the charging handle is way out front & so is the gas block; the bullet is long gone before the gas system is doing anything like loading up the gas cup
3) The 17" model barrel does extend past the gas block a good ways with a small profile; there may be some Mini-14 type barrel whip issues at play here
4) Trigger is nice enough for a 1MOA shooting rifle, but the lock time is necessarily very long because of the long hammer. Would be interesting to see how groups change when the rifle is bolted down & the shooter's follow through isn't able to impact things.
5) We'd need to cast it to know for sure, but I'd bet the chamber is fairly roomy, and the leade nothing to write home about, since that allows for a reamer to cut more barrels before changing
6) The flash hider seems to encourage the formation of fouling around the crown; there's a restriction/throat right in front of the crown that could be causing this.
Summary; "it's built like a battle rifle, not a DMR" cliche. But it's probably true here.
