    First range report on my Lynx 12

    Been having fun @ range w Lynx. Got all loads cycling. Some low brass SuperX 7 1/2 fail to load all the way (fall short by 1/2"). Fixed a ProMag compact15 drum. Out of box it had two full revs on spring, so fully loaded was at three revolutions, this was stopping the feed cycle halfway when the next round below pushed up on round being fed. Set it to one revolution empty....works fine now. Got new Bushnell Engulf 5 moa red dot on top of UTG mount (needed .041x1/4" K&S brass strip as shim to correct slight cant, now bead is centered in V groove). Pic of 50 yard target (butcher paper w 3" circle), paper is 17"x22", two groups slugs, last group tighter 4 above right of target; then shot 1 round 3" Win Varmint BB, and 1 round #2 Remington; SGM Modified Choke & Brake, shot standing position.

    Puck Install Question

    Good info, I enjoy concepts in hi-po engines like flame propagation etc. surface area thing makes sense. That's good stuff. In another post I read where a member suggested welding up the second largest opening of the gas adjuster on a DPH style adjuster (which my SDS looks exactly like) because " it doesn't cover any more of the holes than the next size" and therefore doesn't reduce the gas pressure at all. This is errant thinking. The angle of cut and larger size opening above the gas ports creates a Nozzle in the block, producing thrust on the puck by the expanding gas. In the following math, area A may be fixed, Area Exit is variable by the Adjuster setting, changing thrust on puck/chamber, and block chamber fill rate. https://www.grc.nasa.gov/WWW/K-12/airplane/rktthsum.html Welding and tinkering to put a thumb over a garden hose end approach is guesswork at best. What tooling and scopes are needed to align that welded thumb over the hole to change Area A in the formula above some precise amount? Engineers do things for reasons, I'm sure the SDS and DPH units have engineering behind them. I'll try the Carolina Puck, the stock style has worked fine though all loads, just trying to put some US parts on it, if my gun doesn't like it no big deal. FWIW, the Chinese clone hasn't required any file fitting of CSS Specs or any other mags, new stock and foregrips have fit like a glove as well, just a light tap w rubber mallet and things are going together great. Ive seen plenty of knuckleheads try to outsmart factory engineers in quarter mile motors, just to waste money, go slower, and have higher failure rates. Same can happen in this arena. I came to this forum to learn what works and why, vs. luck of the draw. Based on gas block bore size, I'm sure there is an optimal clearance between block wall and puck ( puck size) to mate with it. Guys with worn guns, or guns made with wide variances in spec could benefit from alternate puck diameters being offered. Or they could try things hit or miss 100x, cuz it either works or it don't. Lynx12 gas block bore measures 21mm Factory Puck 20.98 Carolina Puck 20.94

    Puck Install Question

    That's what I ASSumed to be correct. But there's misinformation out there (2 vids) and alternate definitions of "front" of a gun. It is science actually, developed by people called engineers, they design things to "specs." You can half ass it and go by guess work, I'll measure and record so I then know what worked and why. CS puck likely end up in trash.

    Puck Install Question

    So Carolina ( thanks Carolina!) put it in terms I understand: Puck nipple (raised end) points the direction you are aiming (or faces the gas adjuster cap). That leaves the flat face with "CSS USA" to interface with the action/Rod. I've seen two videos where the CSS puck is installed wrong, the opposite of their instruction. Ive heard the "front" of the gun identified as both the shooter/operators end as well as the muzzle end now on the net. Which is truly correct?? This is why I asked for install instruction in terms of barrel end/muzzle vs buttstock or operator end. Anywho, anyone have 2 cents on puck size issue?
  5. Polarization of society through controlled media outlet brainwash; keep listening to the outlet you agree with (never challenge yourself to other ideas).......exceedingly polarized. Polarization breeds extremes; then bad seeds within either extreme can act out. The political climate is bad. "Diversity" focuses on differences, applies labels, forces you to accept the "other" through laws......again, more effective division created in an attempt to force unity. Divide us, pit us against each other, then enforce peace. Quite a system that's developed/evolved. Requires more and more control.

    Lynx12 Mag wobble

    So far on my Lynx 12, factory mag had most side to side wobble, CSS Specs much less but still a little; MD arms 20 drum 0 side play, super tight going in, and a Magpul 15 drum very minimal side wobble. None of my aftermarket mags needed file fitting, CSS specs was the tightest fit locking in. Bought 2 Lynx at same time, serial #s separated by about 300 units; both same fitment of same mags, bout same side play, and no file fitting required. Factory mag cycled everything fine, 2-3/4", 3", buck, bird, slugs with the most wobble. Only other mag I've tried yet is promag 15 drum; ejects but next round jams in feed phase; I've reduced Spring tension 1/4 turn out of 2 in unit and will test soon. My serial #s are high 6600s and mid 6400 series.
  7. New Owner of Lynx12, love the Saiga style gun. Fun to shoot!!! Cycles everything so far, have had fun varminting at night! I purchased a Carolina Shooters Gas Puck. Should the flat face with "CSS USA" or the face with the raised center be interfacing the Rod/Action? Their website says one end should face "forward" but I'm not sure which end of the gun is "forward" per se. Also, I purchased 2 Lynx 12s (one as gift). Got great deal at Brownells. I purchased 2 Carolina pucks. One puck measured slightly smaller in diameter than the other, and definitely moves around easier in the gas block than the other (in both guns). One was 21mm and the other 20 and change.... is one preferred over the other? ( Tighter fit vs looser fit better)? Also, edges of Carolina puck sharp corners vs stock, relieving edge w rol-loc any easier for wear? The Carolina pucks were 13.6mm long from seat to Rod interface vs. 13.5 on the unit that came in the gun. Both Carolina pucks were same 13.6....but definite variance in diameter. I didn't measure gas block ID....I can do that. Lynx barrel bores were both .730" at muzzle, both SGM Mod chokes were .710" at muzzle for .020" reduction; consistency there. Just checking things out. Anyhow, thanks for info and expertise!
