  1. Run the crow's foot, don't do the math. Don't look back, don't be scared, just do it. At 89 degrees, if you're scared....

    I no kidding missed this picture, completely. Your gas tube is too short. I'm living this issue, right now, and there might be a bunch of people say different, but I'm not interested is seeing what they say - but that gas tube is too short. You have rifle gas system, or "midlength" gas system on that gun?...

    It's really time to start looking into (additional) gas system problems, here.
  4. THIS GUY, RIGHT HERE^^^... Is the one that came up with the Coors Big Cans with the WAY BETTER ballistic coefficient, through the Can Cannon. Last Fall Shoot, he has a JEEP-LOAD of these cans, and says, "Think these will fit it?..." BAM!!! LIKE A CHAMP!!!
  5. 90 degrees eliminates that. Doesn't matter the length. You go straight on, and you increased your leverage. You go 90, you increased no leverage, no matter what the length of that 90. Anything you measure in a difference will be negligible... That is why you run a crow's foot at 90.
  6. She's a beast, brother. Beast. @suzukiray is not gonna deny what I'm sayin'... He knows better...
  7. If you want to do that now, brother - it's right here. I can do that, make sure it's right, and test fire it. Lemme know. I'll give you that YHM lo-pro gas block I picked up. You just need a rail that will mount up - and you probably won't find it as PSA. Look for something in the "DPMS Low Profile" arena, and it'll be best on your gun. I can send it back already fixed, ready to mount to your lower...
  8. Oh, I might add, I don't see a single PA-10 Gen 2 rail for sale on their website. Not one. I'd just run the DPMS Low profile rails, eat the 0.010" through sight adjustment, and call it a day. You could even get the DPMS High rails, and bury the front sight to make up for this. You'll just have a rail-difference like I posted above, but your sights will work.
  9. Because. Proprietary. They knew what platforms were out there, and what accessories. They had to DECIDE to do this...
  10. Those thing get it done, brother. Fill 'em 2/3rds with dirt, and it's just devastating... Those bastards are the "Hornady ELD-M" of the Can Cannon World, right there...
  11. You guys got her number?....
  12. While I'm at it - and since the PSA PA-10 Gen 2 thread pattern is the same as DPMS LR, I thought I'd toss this in there. PA-10 rail height. AP M5s are set up at the old DPMS height (DPMS "High" vs DPMS "Low" - which is NOT that crazy "High-Rider" DPMS Shiit). So, the PSA PA-10 Gen 2 is 0.050" lower than "DPMS High." If there's a 0.060" difference between DPMS High and DPMS Low, that means the PSA PA-10 would be within 0.010" of the DPMS Low rails - well within "close enough to work and make sight adjustments..." You could even BURY a front sight post in a front sight assembly, and run it this way, if that's your thing. Here's the Aero M5 rail on the PSA PA-10 Gen 2 upper receiver:
  13. I've met her, bro. She would kill your Ginger A$s, out of pure hatred for Gingers...
  14. The PSA PA-10 barrel nut threading is DPMS-based, which saves my a$s. I already threaded your Delta-Ring assembly back onto the M5 upper, so I can run your handguard and chopped/shaved front sight base (as a gas block). I have to verify that the FSB isn't restricting gas flow, with that handguard cap on there, which holds the handguards. Once I assemble it all and shoot it again - IF my ejection pattern changes to the "softer side," that means the FSB is partially covering the gas port, and restricting gas flow. Primary reason I watched the ejection pattern closely, and made sure I got a pic of it all. If my ejection pattern doesn't change at all - your upper gets rebuilt and shipped right back to you.
  15. I'm with This Guy. By the way, THESE are the best Can Cannon rounds, right here. WAY better Ballistic Coeficient over those flat-faced cans!!!!
  16. She runs, brother, she runs! Still some others things to do, before I ship it back... Smartass....
  17. 0.085" gas port size is where this barrel wanted to be, from the beginning. Even with some "warm" ammo, there is no brass damage, at all. All the case mouths are fine (I see two in here that got a little "out of round" during ejection). Nothing out of the ordinary, at all, and MUCH better than some brass that comes out of overgassed 16" carbine 5.56 barrels, with 1/2 the case mouths squashed flat... Nothing to see here... move along... The bases look great, too. No issues with ejector smears or ejector swipes (that would be more of an indication of a real hot load), nothing in the rims that would have indicated an extraction issue (that would have been an overgassed issue). This much gas running through the operating system... is where it's happy...
  18. You'll need to find a 2.500" buffer that weighs about 5.4oz, don't just use a DPMS LR308 buffer - it's to light. That buffer from Slash would do it. Where you're at right now with it - H3 buffer + EA1095 spring, the cheaper route is to get the correct extension for those parts.
  19. Here's a vid of the 0.085" gas port test:
  20. Runs like a champ. Nothing wrong with the extractor springs, as far as tension goes. It didn't chew up the brass at the rim any more than any other .308AR I have. I will include a spare extractor spring with it when I send it back, though, just in case you need it on your terrain, Gopher. I had it at 0.081" gas port size, and I'm shooting some "warm" handloads through it, and it should have tossed that brass forward on ejection (with those loads). They went out to about 4 o'clock. I don't use that "clock pattern for ejection" as a sole indicator of how the gun is running, gas pressure wise, but it is another tool you can use. So, up in size the port went, to 0.083". That was better, but not what I was looking for. Up again, to 0.085". THIS I liked. Kicked the brass to the 1 and 2 o'clock positions, which is about what this load does on my others. So, set up like this, it'll handle hot loads, weak loads, off-the-shelf whatever you find. I have a box of CBC somewhere that's kinda weak, and should have used that, too. Didn't grab it. I'll look for it and try it. Here's the brass, as it landed from the rifle: Total changes: Armalite AR-10 Carbine gas tube, gas port went from 0.073" to 0.085". It runs, well. I still need to test if with your front sight base as a gas block, and make sure it's not obstructing the pas port in the barrel, so there's still a little bit more to do to it, but it's not much.
  21. You know your wife, Viv, will take this thing from you right? Its not your's... it's HERS... I"m just sayin'...
  22. As sad as it is to read that - that is every single day on every single street, these days, for police. That's what's really fucked up about it. I'm glad she fucked that guy up, and I'm glad her dog got some work in, too, and bit the fuk out of him.
  23. I'm going to tell you guys right now that I straight-up contradicted myself. I drilled that gas port already, to 0.081". That port size of 0.073/4/5" whatever it was (under 0.076"), is just too small for an 18" midlength-ish gas system in the .308 Win AR. I punched it already. And, it may go north of that, for reliable function...
  24. You did a damn great job on it, that's for sure!!!... I snatched up an ARFCOM lower when they first announced them, based on that design...
  25. That's pretty damn cool, right there! I see alot of the lines of the MagPul lower in that, which is an incredible design. That's badass, kiwi!
