    Lynx?

    So file the inside of the rear trunion a little wider?
  2. So, don't think modifying a ready made receiver, particularly one which was originally designed for box fed would be within the scope of the patent in the above post.
  3. https://patentimages.storage.googleapis.com/61/2a/e6/6529e1d1db24b3/US8756846.pdf I looked through this patent, which admittedly I didn't fully parse out. As near as I can tell by casual reading, it's only real claim is having a conversion receiver, not modifying an existing receiver. It's scope is for conventional shotguns, and it very broadly names every normal feature of any firearm, right down to firing pins and feed ramps. Those are clearly extraneous to the claim. Given that box fed factory pump guns have come from both Italy and China in factory configurations some of which I
  4. You need to learn about ammo. If you googled around this forum, you probably saw a lot of very similar posts, which usually included someone like me posting this: BOTH: Find the minimum ammo your gun will run. buy stuff with that rating or larger. Notice how SHOT SIZE is not on the list? That's because it doesn't matter at all. You care about weight x velocity. If you refuse to learn that simple lesson, you doom yourself to a life of frustration with every semi automatic shotgun. It is easy. Learn the lowest combination of numbers that each gun likes, and buy stuff that is equa
  5. Looking at that patent, it is for having the mag in two pieces to cheapen manufacture and make it easy to manufacture modular feed towers for different guns. Kinda surprised that was granted as non-obvious. Several guns out there have had modular magwells, and I know the maxrounds drum came with mix & match feed towers, so that's a prior art. It would be infringing to make that magazine, but I don't see how it would infringe to USE the magazine in another gun. i.e. buy a mossberg mag and fit a gun to it. Or alter mossberg mags, and obliterate the logos. That would be under first sale
  6. 5 ports is good, but diameter could be an issue. Does the version you have come with the feature that disables the gun if the stock is folded? I am wondering if that could be introducing friction to the system.
  7. Which patents?I have looked through the list of patents from or assigned to Mossberg, and none of them seem specific to the mag tower.
  8. I am not an AK VS AR guy, but the inherent design of the AK trigger is substantially better than an AR trigger. AR puts all the critical surfaces at the pivot point for peak leverage and friction, and AK sticks them at the end of the lever, where you can have a strong hold with the effects of springs and imperfections minimized. No matter how good the steel is and the fitting at the sear engagement, a conventional AR trigger has to be heavier and rougher than an AK trigger with the same quality at the engagement point. Put your friction at the long end of the lever, like an AK, not at the
  9. The one Sergeii had was clearly a one off shop experiment for the factory team. Their new guns don't have it, so either it didn't work well or it didn't work well enough for them to bother. Also, around that time Molot was making AR15s for their factory team, as was IZH. I think they realized that it was poor branding, so they went back. Imagine if the chevy nascar team put a wrap on their cars to make them look like mustangs, or worse actually used a chevy manufactured mustang. Marketing over function. -- we sell AKs, make sure they look like AKs.
  10. I think you could lathe turn a plug shaped like two AR buffers back to back, so that it would stay captive, but still reach the back of the carrier. Might have to be thinner on the front to clear the trunion.
  11. No. this was an AR buffer tube with a delrin piece which the carrier hit, which transmitted the force to the AR buffer. IIRC. They had to clearance the rear trunion and fab something to keep the delrin chunk in place if I am remembering correctly.
  12. I bought a little cellphone to tripod adapter clamp off'n amazon for $7. I had it for a few minutes before I worked out that I can rig it to mount off a tube on my forend and line up with my scope for video. Does that count as a firearm related purchase?
  13. Sergei Orlov once posted a few pics here of A vepr factory team prototype which had an AR buffer tube on it, and a little widget which connects the carrier to the buffer weight, newton's cradle style. IMO it was brilliant. There's your ticket. Not actually all that hard to make either.
  14. Good deal. I thought I converted a lot of BO, but it goes fast. I had temporary access to one of those chop saw and jig setups and so I chopped all the brass I had on hand, some of which turned out to be on the list of brass not good for BO... I use the lee dies too. However, trying to make stuff feed in multiple guns prevents me from loading right up to the lands. If you can get an eliptical, I really think those are better exercise. Way easier on your joints, and they work more of your body. Chintzy ones squeak and aren't as fluid of a motion. The main thing I like about them is this:
  15. I hear really good things about the 125 grain SSTs and have seen impressive hunting photos of those on whitetail. They are definitely in the top few for terminal performance, and would be a good HD choice.
  16. I just checked and I have some 148 grain versions of that bullet a little softer alloy. I might give your recipe a try. Thanks.
  17. Thanks. I probably won't run anything which requires me to down tune my gun, but I do have a bunch of self cast 155 grainers, and IMR 4227. I also made a custom mold for ~125-130 grain SP depending on the alloy. I have a 170 RNFP too, and expect to have a nicely streamlined ~168 grain mold soon too. (by chopping down the poor Lee 211-230-5r from the base.)
  18. Funny this topic comes up. Keep at it Jerry! I was at the bank yesterday and an older guy was slowly working his way out of his car. I kinda hesitated and he recognised what I was thinking, and told me something like "thanks, but I got it, it just takes me a while." I congratulated him. My grandfather just turned 95 and has had his neck/back broken or cracked at least 4 times that I am aware of, and has damage to his knee from running into a stancheon on his way to shoot at a zero. Also nerve damage in his feet. He stubbornly insisted on walking even when it hurt. A few years back he
  19. Yes, and. My brother has a personal CNC machine. My cousin gave me his jigs from tactical machining. So I modified the jig to be an easier way to hold the blanks in the CNC all trued up. Sort of a fixture I suppose. Otherwise holding a lower true in all the axes to the cutter so that engraving doesn't look like garbage would be a real pain. Engraving with a conical cutter really shows any variance in the Z axis/ surfaces that are supposedly true in the horizontal plane. i.e. the magwell, and the areas where the markings go near the safety selector. I kind of suck at drafting,
  20. I like 80% partly for the ability to machine or etch my own markings or not.
  21. Look up dinzag arms http://www.dinzagarms.com/
  22. I was on the fence. In the end I didn't shoot the elk, but I felt bad about it. I think it probably died within a minute or two anyway, though I would have preferred to shorten that time. The deer I hit later died before it was skittering down the freeway. I can still see it's antlers shatter in slow mo, with the velvet sloughing off in the impact.
  23. They are often cheaper than that. A lower is a lower. Snobs will disagree, but they are functionally the same piece, made from one of the same forgings as the other brands.
