What I'm gonna do is when the partial order is in, I'm not gonna post it on my SixFiveArms.com website until I post here and you guys email me to get on my list for first dibs.

But don't email me until I say they've arrived. Then however many speak up here, I will reserve that many.

While my Mod1 lug rim walls have about 25% more metal than my standard bolts (see photos 1–3 and guess which is my standard bolt and which is Mod1), this has caused the top of the extractor to scrape and bind against the barrel extension teeth (photos 4–5).

The new bolts worked just fine during my live fire function testing in both 6mmARC and 6.5 Grendel due to the more extreme forces, but they bind when hand cycling, such that I needed to mortar about 7 out of every 15 — and I needed to use a mallet on at least 1 of the 7. (I hand-cycled using a dummy firing pin that I grinded off the tip so there was no danger of an accidental discharge in the house!)

The 25% gain in metal thickness is awesome. Not so much the extractor tolerance issue I've created for myself. Am gonna keep the Mod1 bolt bodies as is cuz I love the increased strength, but that means I gotta tweak the extractors. The silver lining to that is I've been meaning for years to optimize the 6ARC/65G extractor and events are forcing that to happen.

Anyway, don't know what to tell you guys that have been waiting so patiently. Very sorry to disappoint you. Can't in good conscience sell these as is that only work upon firing and not during hand cycling. Am working out a solution with the vendor, but in these crazy times that's at least three months out.

Too bad about the delay, keep me on the list for 2 when you get them!
