It's uncanny brother, I'm telling you. I blew a circuit breaker or two when I became aware of DEWS. It was only a joke at first, I have long been a believer for a long time now.

The decision to filter language here was made by the ownership, and it's not anybody's call to undo it at a lower level, so those of us who know and respect the owner honor his decision. If you get banned, it'll be because a staff member made that decision for the good of the forum. Freedom is freedom on private property too, yet the owner still gets to ask you to play by his rules in his house. Same idea here, and the restrictions aren't unreasonable.

Magpul's FB page had a post saying they'll roll out in August, I guess we shall see.

Definitely. Heavier buffer = more cycle time.

I'm pretty sure your recoil cycle is way too brief, needs to be a bit longer. That's a two-factor problem, the right gas system setup is the first component, and a heavier bolt carrier group is the second. I would address them in that order.

Gotcha. Here is what I was basing that on... I think I understand your problem now... When the failure occurs, is the bolt behind the fresh round, or on top of it?

Uh oh, obsessive package tracking is the primary symptom of Matt Cross Syndrome. You might want to call your Primary Care provider if you find yourself experiencing other symptoms, such as finding yourself filling out credit card offers from your junk mail.

Where's the oil? Why is the oil always gone?

That's physically unpossible my friend. You're saying that in the firing sequence, the bolt extracts the fired round(evidenced by the case mouth being dented by the locking lugs on your barrel extension), strips another cartridge from the mag, and then chambers the stripped cartridge with the spent cartridge trapped behind it. That's physically impossible. Based on the pics and the bent cartridge here is what I see happening when this occurs; the bolt fails to travel far enough rearward to properly strip the next cartridge, and begins to travel forward again before the extracted brass can clear the receiver. On the way forward, the bolt frictionally grabs the cartridge in the mag and pushes it into the barrel extension locking lugs where it bends and ceases to move, the bolt continues forward stovepiping the spent brass. That's my assessment.

They're available for pre-order on Optics Planet.

It's all about the bolt travel, I think it explains both issues; why you couldn't get bolt lock back, and why the bolt is overrunning the cartridge in the mag and catching the spent brass. The bolt simply doesn't travel far enough to the rear to catch the rear of the next cartridge. You may have an out of spec bolt carrier group, recoil buffer and/or action spring, and/or buffer tube. Maybe even all the above. I suspect your recoil buffer/spring/tube are the source of your issues, and that once you get that to spec you can go back to an unmodified bolt catch.

If you would answer your phone, I could tell you.

Not one, but two Magpul bipods!

We need to invite her to the Fall Shoot!

TactiCat is hilarious. If you try to buddy up to him, you'll be rebuffed swiftly and with extreme prejudice. Totally ignore him and do your own thing, he'll insist on introducing himself within minutes. He's absolutely nutty, just like his caretaker.

This is going to take a while to do, some poor draftsman gave a lot of time and effort to the prints for this beast, but they're comprehensive!

I'll go over the prints and see what it'll take to CAD it.

Careful... You make it sound like too much fun and everyone will want a piece of the action. They'll be so distracted they'll forget to shoot your 6.5 Grendels.

I'll make you a CAD file if someone sends me a receiver, for reverse engineering of course.....

Hi Tom!

This has vastly increased the rate at which I drool all over myself...

... and the ol' willie retreated so quickly it banged it's head getting back into the bunker! Been there done that brother. It's bound to happen to everyone sooner or later.

That's what she said.

Jealousy is a bit much, envious would be more like it....

That's a great looking compensator! I love machine work!
