  1. FA upper, port door, and SSS Gas Vent showed up yesterday. Got the kids to bed, got Momma off to work, and got the receiver lapped. Unlike the AR-15 uppers I got from FA, this .308 upper didn't take much. In fact, all I did was lap the anodizing off. No unevenness at all -- just a nice, shiny solid ring. Then I installed the port door and gas vent. I'm not sure how much I like the fit of this upper to my lower. But, with them not being purchased as a matched set, I can't fault FA. I'll sand down one of my Accu-Wedges tonight and get it "just right." Next up is dismantling the Gibbz upper. I'll be dropping the barrel off to a friend to have him "touch up" the sandblasted finish forward of the gas block. When I installed it, I hadn't thought about how snug a fit the gas block would be, so I have shiny lines all the way to the muzzle. Lesson learned -- a small metal shim on the non-threaded side, and run the clamping screws in from the threaded side to spread it open a bit. Debating on going back together with a SLR Sentry 7 I have lying around... I can already hear the immortal (immoral?) words of @98Z5V, though... Don't complicate shite with complicated shite!!
  2. I finally just bit the damn bullet today and ordered up a FA upper. Along with a port door and gas vent instead of a forward assist. Does the vent help? I dunno. Can it hurt? I suppose not. There's another $200(ish) in this build. But if it gets her to the range and running, it'll be worth it. That Gibbz upper will make a nice conversation piece in my office. I can't, in good conscience, sell that fvcking thing down the road to someone else.
  3. Okay, so lack of sleep due to an infant and a spouse working night shift has got me messed up. I just checked GunBroker, and the best price I could find for an 870P Walnut is $449. The 870 HHD is available at the $399, some as low as $343. So the 870P is out of my range -- I can't justify (to myself, let alone the wife...) spending that much more for heavy springs, a metal trigger group, and parkerized finish for a HD shotgun for me. If I want the shorter, "corncob" forend that bad, I'll pick one up from Remington or Numrich and swap it.
  4. I did find the Retrograde, both the 500 and the 590. From what I've been able to figure, the 500 Retro is going to be about the same money as the 870 HHD. One extra round in the 870 edges it out a bit for me. Also, while doing some more looking for a patrol shotgun for the wife, I remembered Remington has a specific, separate LE/MIL website. "Hey, SWMBO is LE... Let's check it out." The 870 DM is not available as a "P" model yet (don't know if it ever will be...), so I think she's off the idea of an 870 DM for a bit. Because she wants the same quality shotgun as what she's been carrying on duty. Of course, I had to check out their other "P" models. And... 870P BS (Bead Sight) 6+1 Walnut. A seller on GunBroker has 4 listed at $399, just $15ish more than what my local gun pusher wants for the 870HHD. From what I've been able to glean online, the "P" series has several reliability upgrades over the commercially-available version, including heavier action springs, a metal trigger group, and parkerizing (which, frankly, while I like the look, parkerizing by itself doesn't move the needle for me). So... ? 🤣
  5. It's funny you say that... She was texting me last night while she was on duty, letting me know some sh¡tbirds (technical LE term of art) moved in around the corner from us, to lock up the gun safes before I went to bed, make sure the camera system was set to "nighttime mode," and to keep my nightstand lockbox (w/ XD .45) unlocked and "at the ready," because it was just a matter of time before they figured out where she lived (a car with a light bar and reflective P O L I C E emblazoned on it is kinda hard to miss...). My response was, "Okay, will do. Is this a good time to mention I've been seriously considering a 'real' home defense shotgun, not just my fun little Mossberg .410 I bought an 18" barrel for?" She asked what I was looking at and what it'd cost. Hehe... I really dig that. Never really been into Ithacas, but after I fondled a Stevens bottom-eject pump many, many years ago, I've thought it was a neat concept. That's still about twice the price of the 870. Hell, I could pick up my wood-stocked HD scattergun and an 870 DM "MagPul special" for her for that kind of money. Also, since her issued shotgun has been an 870 since she started 11 years ago, I'd just as soon stick with what she knows and is comfortable with in the event she needs to use it.
  6. Now that she's back in patrol from CID, the wife has decided she'd like to have a personally-owned shotgun to go with her personally-owned (and built...) rifle. So I've been shopping. She prefers Remington 870s. Personally, I'm a fan of the Mossberg pump guns. She wants an 870 DM. I, personally, would prefer to give that platform another year or two to prove itself, but Momma gets what Momma wants. While browsing for her shotgun, I think I stumbled upon my next firearms purchase... The Remington 870 Hardwood Home Defense (81197). 18.5" barrel, 6+1. I've been trying to figure out how to modify a Mossberg 500 to accomplish the same goal, but it seems (from my limited -- nonexistent -- knowledge of modifying shotguns and a quick thought about how my 500 in .410 comes apart) it's impossible to extend the magazine tube on a 500. A 590? Sure. But buying a 590 is going to cost me a substantial amount more than the $385(ish) that the 870 HHD would.
  7. I stumbled upon this over at RimfireCentral...

  8. ...and it’s a damn shame, because their idea is brilliant. But the execution is apparently piss-poor...
  9. No offense taken. I haven’t posted about Gibbz problems before, but now that you mention it, I do seem to remember someone (maybe you?) mentioning previous problems, either in this thread or in the “anybody know anything about these?” thread I started. I didn’t check out those threads, but I figured surely they’ve got their problems worked out by now. Fawk. I actually called Gibbz this afternoon to ask WTAF could be the problem. They blamed Criterion and NLA (“that’s a pretty new BCG to the market, maybe they haven’t quite ironed it out yet”), then said, “If you hit a wall, send it to us and we’ll see if we can figure it out.” No, thanks. I’m having Mike headspace me a bolt. I figure it can’t hurt to know it’s been hand-selected by CBI. I’ll try ‘er out — by hand — with live rounds. If she won’t work, I’ll try various combinations of NLA, FA, and DPMS carriers and bolts to see if I can find something that’ll check out. If still no dice, the Gibbz upper will go in a parts box for “one of these days” when I have the time and patience to dick with it. Then I’ll bite the bullet and pick up a Fulton upper on sale. I’d love a FA side-charger, but that’ll require another $175 for a carrier. So it’ll be a standard upper, and I’ll throw the NLA carrier, FA bolt, and my TacOps Sniper in it.
  10. I heard back from Mike at Criterion Barrels today... He says the NLA bolt I have is "within tolerance," not way tight, but within tolerance. He says he can go ahead and select a Fulton bolt if I'd like, but he can't promise it will improve functionality or accuracy over what I have. He also said the NLA bolt closed on a GO gauge, and would not close on a NOGO gauge. I asked him how that could be, when it wouldn't close on my Forster GO gauge or a live round. He didn't know, other than to say that, in his experience, left-side charging upper receivers tend to have reliability and accuracy issues. He also said my receiver isn't DPMS-spec, in the truest sense of that phrase. I'm at a loss here. My headspace gauges are telling me there's a problem. My range experience is telling me there's a problem. CBI says there's no problem but, if there is, it's with the receiver itself. I've just about resigned myself to having Mike fit a Fulton bolt, ditching the Gibbz upper in favor of a Fulton "standard" DPMS-spec upper, and calling it a day. But dammit, I hate to do that. I've got $350 in that upper. And I won't offload it on anyone if I suspect it's got issues.
  11. No problem. So long as the quote is all there every time it’s used...
  12. True. I never said a GO gauge was the only way to get it done. But I have a tool specifically for that purpose. I’m a tool queer, and I freely admit it.
  13. Headspacing is a very real concern with large-frame AR-pattern rifles. Even using quality parts from reputable manufacturers, you can have an issue. I'm extremely fortunate that my "CSASS" rifle (Gibbz upper, Criterion barrel, Next Level BCG) didn't blow up in my face the first time I took it out. Chambered a round (or so I thought, from behind the rifle), dropped the hammer, and got a "click." Had to mortar the unfired cartridge out. I could swear I checked the headspace after I completed the build, but apparently I didn't. If I had, I would have known there was an issue. After checking the headspace, where the rifle wouldn't go into battery on a GO gauge, I sent the upper to Criterion to have a bolt fitted for it. I'd highly recommend having a full set of Forster headspace gauges (GO, NOGO, and Field), or at least GO and NOGO, for large-frame ARs. In my case, if I'd only had a NOGO and Field gauge, I still wouldn't have discovered the issue I had. Because, well, the bolt isn't supposed to close on either of those gauges. But it is supposed to close on a GO gauge.
  14. Hell, they don't have a warning -- they have exactly the opposite. I'd be hard pressed not to demand a full refund on the completed lower, and a return and refund on the untouched lower...
