I'm in the process of accumulating parts for my LH 6.5 Grendel build. It's going to be rifle length not carbine. Intended use will be a hunting rifle for longer ranges. So far all I have are a CMT billit left hand stripped upper, An Anderson forged stripped lower, a stag arms left hand bolt carrier and an ambi safety. Future parts are as follows. An underground tactical left hand bolt, a BHW 20" barrel standard or light profile with rifle length gas port, a diamondhead VRS-T hand guard 15", a drop in trigger, single stage 3#( haven't decided which brand ). Also an ergo grip and A5 buffer tube Assembly. I haven't decided on a stock , scope or scope mount yet. I have lots of questions. BHW only makes the type 1 chamber. I've read many posts that say the .136 bolt face depth is better due to the thicker extractor lip/claw. Underground tactical make both type 1 and 2 bolts. If I get the barrel and extension in type 1 from BHW, and the type 1 left hand bolt from underground tactical, will the headspace be correct or will I need to buy/rent a set of go no go gauges? Will the bolt work properly in the BHW barrel extension, being that the bolt is left handed? I read something about chamfers on the lugs in the barrel extension. Also I read where Bill Alexander says that in barrels 20" and longer that the 1-9 twist is better. These are my first few questions. If anyone who really knows, has some good advice, please reply. I'm sure I'll have more questions in the future. Thanks Jeff

Th barrel will be fine with your LH set up. My two seem to run pretty well..LOL As for the extractor being better that is pure unadulterated BS. Nothing from an engineering standpoint can support that theory including drawings on the back of an envelope are bandied about.
No need for gauges.It will be good when you get it. Twist rate is based around velocity and bullet LENGTH. I would do a nine but nothing would preclude you from using an eight.

Thanks for the reply. I'm about to order a 20" standard profile stainless finish. I hope it gets here before next deer season. I've got upper and lower, BCG and ambi safety. Got to get LPK, trigger, stock and hand guard. Can't decide on fixed rifle stock or adjustable. Thinking about a primary arms 4x14x44 ACSS FFP Orion scope.
