Look this explanation over:
When I measured my "sample" dedicated Grendel bolt (from the monster buy I just received), as BFT states, it comes out 2.810" and it uses, then a pin of length 3.279 (this would be the standard AR15 pin length then +/- 0.001?) and has a bolt face depth of 0.135" as-measured. So BFT's explanation lines up with this I believe, +/- 0.001.
The Toolcraft bolt ("Toolcraft 6.5 Grendel Bolt Carrier Group," sku TC65GBCGBN), however I found to be shorter, at 2.799", (so this looks to be a Mil-std AR15 length bolt within 0.001?). And the Toolcraft pin I found to also be shorter, 3.267".
Bottom line I was trying to say, is if you get a Toolcraft-like bolt for Grendel then make sure you're using a Toolcraft-length pin.
Sorry for all the confusion, I hope this corrects the record and straightens it up.
