IN STOCK Hybrid MONSTER Bolt - BluntForceTrauma - 08-17-2020

Guys, while I am working on the Ultrabolt project, I decided to offer what I have for sale.

This bolt is my improved Ultrabolt body, but has a standard Grendel extractor because the new and improved Ultrabolt extractors are not done in manufacturing yet.

I've sat on these, waiting for the new extractors, because in my testing I experienced binding upon extraction with a standard extractor and the new Ultrabolt body. But it seems that I was in the minority among my testers. Most have had no problems with this hybrid setup.

Sometimes the perfect is the enemy of the best.

So, I've decided to offer these hybrid bolts at a special sale price of $55 each. Once the new extractors are complete, the price will go up because they cost more to produce.

At the worst, any binding will resolve as the parts wear in, and, at any rate, the new extractors will be available separately once manufactured.

----------------------------------------------------------------------------

Bolt bodies are made of 9310 steel and black nitride treated for all-weather durability.

These fit in standard bolt carriers and take standard firing pins.

Cool MONSTER logo laser-etched on the bolt!

SAVE on shipping when ordered with a MONSTER barrel.

ORDER from SIXFIVEARMS.COM.

(Same bolt for 6mmARC so tell your 6mm buddies!)

BFT...my two bolts arrived today. They're gorgeous.

Thanks for the fast shipping. I needed them as I, ahem, sheared my original Grendel bolt a few days ago developing a 107 SMK load. I think I was over pressured. Wink

65G or 6ARC?

Got mine and the 12” looks great. Now to buy the rest of this pistol. Not until your 12 son.

65G. I'm thinking I'm doing the 6ARC in a bolt gun. Things change though Rolleyes

That was quick. I was not.

U P D A T E : Next batch of MONSTER bolts is due in about a week as of today, Friday, September 4.

Hey there, any word on these? I put one on backorder last Friday. Thanks!


IN STOCK Hybrid MONSTER Bolt - BluntForceTrauma - 09-12-2020

Bolts were due Friday, and it's Saturday today. Will bug my guy on Monday to see what's up.

Would these be considered the equivalent of the AA ‘hard use’ bolts?

I just looked at AA web site and they have discontinued using the term “hard use“ bolt. An AA bolt cost $93.50 plus shipping and maybe sales tax. I have at least one AA bolt and several Monster Millennium Manufacturing bolts and I can see no difference in performance or wear. At one time I think AA sourced his bolts from Millennium Manufacturing. For the price I’ll continue to buy bolts from BFT and keep at least one spare. Hopefully BFT will chime in but Maxim bolts and JP bolts ($$$) get good reviews as do the current Toolcraft 6.5 Grendel BCG.

Thanks, Vascar.

AA used to sell two kinds of bolts: the standard model and the "hard use." The hard use had a U-shaped notch taken out of the rear of the lug that was opposite the extractor. Theory was it would help even out the stress load on the other lugs. I believe it also used a more expensive alloy that was not necessarily stronger than the 9310 alloy used in AA's (and now the rest of the industry) bolts, but was more resistant to micro-crack formation and the resulting metal fatigue.

Bottom line: The "hard use" bolt was supposed to last for a longer round count under full auto fire before a lug broke.

Photos attached of original AA "hard use" bolt.

I couldn’t remember the exact difference in the AA Hard Use bolt. I knew it had something to do with the lug design so thanks for refreshing my memory. I was surprised the Hard Use bolt was not on AA web site but maybe sales had diminished and they stopped stocking them.

That's what I would guess.

U P D A T E : Bolt rep says bolts are bottlenecked in QPQ nitriding. "Soon," he says. But they always say that. Cool


IN STOCK Hybrid MONSTER Bolt - SCRhino - 09-25-2020

Any word?


IN STOCK Hybrid MONSTER Bolt - BluntForceTrauma - 09-26-2020

Bolt rep says bolts have been held up in nitriding for THREE WEEKS.

He's waiting for word from them, and then he will update me, and then I will update you guys.


IN STOCK Hybrid MONSTER Bolt - BluntForceTrauma - 09-29-2020

U P D A T E : Bolt rep says bolts are back from nitriding and are now in assembly (adding ejector and spring and roll pin, extractor and spring assembly and pin, and gas rings).

Then they go to lasering to etch on my logo.

THEN they ship out to me and THEN to you guys.

Uff da....


IN STOCK Hybrid MONSTER Bolt - BluntForceTrauma - 10-02-2020

U P D A T E : Bolts are BACK IN STOCK.

Get 'em NOW cuz bolt rep says batches are few and far between in this current climate.

Backorders will be shipped ASAP.

ORDER on my SixFiveArms website HERE.
