  1. MPX recoil impulse with any ammo will be more "forgiving" than any blowback gun with that same ammo. Does that matter when doing static drills with a perfectly tuned blowback gun? Probably not, especially if you've got thousands of rounds behind the trigger with that blowback gun. Does that matter when you're on the clock, running through a stage changing levels/distances/target types (mixed steel and paper)? Absolutely. Does that make the MPX absolutely superior to a blowback AR9? Nope.
  2. L&M Precision can convert the X5 to RMR foot print for $45. Not sure if that applies to the newer ones, but worth checking out.
  3. I ran a Kaw Valley gen 2 BCG in my Colt pattern AR-9. Only issue I ever experienced was a broken firing pin which was caused by the Hiperfire trigger I was using at the time. Should also note that I never experienced a failure related to the bolt. Discovered the broken firing pin during routine cleaning. It had been ~500 rounds since the last cleaning, so no idea how many it fired wihle broken.
  4. Give the Timney a chance. Mine broke at 4.5 lbs out of the box, but after several hundred rounds it's closer to 4 on the guage and feels lighter than that.
  5. I've used CLP on everything that required oil for the last ~15 years, I have not found a reason to try anything else. I've got an M16 that has been through a LOT of 1,000+ round range days with most of it being suppressed. If CLP was going to fail, I'd have seen it. I will say that after a long day of suppressed full auto, when I'm caked in blowback I do wish it had that minty fresh frog lube smell
  6. I run the Comp-Tac pouches. No issues with retention/removal with 41 rounds of Sig/TTI goodness. Used the Colt mag version of the Comp-Tac pouch last season with 1 on the hip and 1 horizontal in front and never had a problem.
  7. Most of the problems I've seen with PSA PCCs have been related to the ejector angle and have been easily corrected.
  8. "Because I can". If you feel like you have to justify your purchase/ownership of any firearm to anyone (other than a spouse who may be impacted financially), you're doing it wrong.
  9. I built a ~5.5 lb blowback AR, ran it for a season, and loved it. Decided to switch to the MPX platform for less dot movement, it's about 1 lb heavier, but totally worth it.
  10. See if you can find someone local with a sight pusher. Removing sights isn't rocket science, but I've seen to many "slips" that resulted in nasty marring.
  11. I'm a big fan of the CompTac PLM pouches.. They're well built and did a great job holding fully loaded Colt pattern mags horizontal on the belt while my uncoordinated ass plodded along.
  12. I have that buffer with a carbine buffer tube and ~2,500 rounds through my build with no buffer related issues. ETA: Check the QA section of the Brownell's listing.. It's designed for a carbine tube. https://www.brownells.com/rifle-parts/receiver-parts/recoil-parts/recoil-buffers/ar-15-fm-9-heavy-buffer-sku100024850-105914-203715.aspx?rrec=true
  13. I.D. is 1.95 x 1.4 O.D. is 2.2 x 1.6 (not including the height of the short section of rail at the muzzle end) ETA: that o.d. was from the bottom of the muzzle end which has a short protrusion. O.D. not including the section of rail or the protrusion is right at 2 inches
  14. Measuring from the lower half of the muzzle end: To the far end of the hand guard is 15.75 inches To the point where the top of the receiver ends is 12.125 inches I don't have a scale, but in a other thread I saw the weight listed as 11.2 ounces
  15. Made it to the range on Saturday afternoon and ran 250 rounds though the MPX and I'm pretty well thrilled with the way it handles. Double taps were unfairly easy, and a 30 round mag dump as fast as I could pull the trigger resulted in a ~2 inch hole in the target at 20 yards. Of the 250 rounds, 200 were S&B 115 grain stuff and the rest were Magtech 124. In my AR9, the 115 grain stuff caused significantly more dot bounce, but with the MPX even when I mixed them up randomly in the mag, I couldn't tell a difference. Next stop is ILWT to pick up some spare parts. Is there any reason not to go with their spare parts kit vs. buying individual bits?
