Calls Shots

Calls Shots (8/11)

  1. Cool, I may give it a shot. Might just pick up a Sylvan as it's a bit simpler and don't have to worry as much about mag changes.
  2. So was it simply inserting the Stern and go, or did you have to fiddle with the adjustment screws at all?
  3. Interesting. I have a Stern adapter (which I used in my main PCC before getting a CMMG RDB system), and yeah I can see that you have a little adjustment with how high it sits in the receiver's magwell. I already have the Mag inserts for the RDB system and they work great....only thing I'd really be gaining with Glock mags is greater capacity than 30 rds when shooting steel or such. Really like the curved true double-stacks CZ Scorpion mags though, especially the 35-rd ones made by PSA.
  4. Probably where the sear hammer notch. So it's just enough to hold when it's cocked manually, but unfortunately once it fires it won't stop until mag is empty.
  5. Yeah that can happen on a lot of AR-based bolt carriers. I eventually just got a feel for it and use the punch to help guide it.
  6. Man....if they were able to make an AR-V lower that would work with a CMMG RDB upper.......I'd be in heaven. Albeit, that's a bit redundant since the PMAG-inserts specifically for the RDG work great. But if you want more than 30-rds/mag....it'd be kind of the best of both worlds.
  7. I did the same. The 35 was a quicker and more natural position to snap to. I was 'searching' and having to center the dot more at 45. My LPVO has 'higher and lower' end caps for the windage/elevation because one houses an extra battery. I put the higher cap up top on elevation, and the other on the side and it just stays out of the red dot window, even though it's relatively wide (Swampfox Justice), as I have it mounted ahead of the scope instead of behind. I also have the Primary Arms LPVO. As I mentioned above, if you have one cap that is 'higher' because it houses the extra battery and it's on the side/Windage, switch it with the elevation one which is shorter. They should be the same threading. But then also as I mentioned, I have my offset red dot ahead of the scope not behind it, so that may have an obstruction either way if you have it behind/closer to your eye.
  8. Right now I'm using a Magpul ACS-L w/ extended buttpad because I adjust length between two uppers depending on which multigun rifle shoot...mainly due to the ranges of the particular match. For my 14.5" (with pinned/welded brake) upper for shorter-range matches that are out to around 100yds max, I use a 1X Prism scope and put the stock at 13.5"" pull length. That's my natural pull length for a red dot or the prism mainly upright. For my 16" upper with a 1-6x LPVO when ranges are farther, I pull the stock out one notch to a 14.25" pull length to match my cheek weld to the LPVO's eye box when I'm shooting supported or prone, and just keep my cheek weld and push forward into eye box when upright. I have a pretty wide jaw so the widely-sloped stocks tend to push my head out too much when I push my cheek weld in. But the ACS-L's is still narrow enough that it doesn't, and I still get a stable and repeatable cheek weld that's just right for the LPVO. I never used to think I'd want that much length of pull (3/4" longer than a standard A2!), but that's what I found most comfortable while hunched or prone, and so I don't have to push my scope length/mount too far forward (and onto rail). It took a little while to find it, and I had higher scope mounts and it was closer with the shorter LOP, which made me have to arch my neck back when prone or supported/kneeling. That sucked. Found it much easier to just lean forward into the scope more when upright, then when prone/supported it's right on. Also, the ACS-L is a nice, wobble-free snug fit.
  9. I use a Hiperfire Hipertouch Reflex on both a PCC and a 5.56. They come with two sets of springs for a trigger that's light and one that's extra light. Clean single-stage trigger.
  10. No angled fore grip now? Is that recent?
  11. https://cesar-shop.com/firearm-parts-en/pistol-en/trigger-sistem-en/cz-shadow-2-shadow-sp-01-petelin/?utm_source=newsletter&utm_medium=email&utm_campaign=hot_this_week&utm_term=2021-03-12 If you have tried it out, how does it compare in shape to the 'old style 85C' trigger? The latter I have on two SP01 Shadows and like a lot.
  12. Yeah, sounds like what was happening with mine. The spring for the disconnector was incredibly stiff out of the box, as if it wouldn't compress at all. So consequently firing/cycling would feel like a jackhammer slapping back on your finger, you could feel the hammer just struggling to put the disconnector back just to hook it. You just couldn't move that 'hook' back at all. But after about 200-300 rounds it began to soften and then you could barely feel or hear the 'click' as it engaged the disconnector upon dry cycling. And that's when I got a six-round burst at the range then recreated it on the next shot. So I think it just bound down and flattened this spring, or it was like the spring was already completely compressed before and this just crushed it.
  13. I had similar things happen with an RA140 trigger. Turned out that the disconnector spring had compressed and was basically ineffective, so the disconnector wasn't catching the hammer after cycling. I replaced it with one from a mil spec trigger group, having to put the tapered end down to fit in the bottom hole but it functioned fine and has been normal since.
