  1. Thanks for posting. The bushing is certainly of interest. Comp might be for a rifle. What is the thread? What is outside diameter?

    Thanks

    Not a rifle comp, advertised by Tandemkross for the Ruger 22/45 and Tactical Solutions uppers. Outside diameter is .998, the same as the TS conversions and the 22/45 Lite barrels. The comp has the standard 1/2-28 threads. Since the standard diameter of a 10/22 rifle bull barrel is .920 this comp would fit on one pretty well although for the 10/22 I prefer the Allchin two port rifle comp.

  2. Not sure what you're looking for, are you talking about a standard Pro-bore tube, or the Breacher Tube that comes with the gun?

    Overall length of the breacher tube is 3.995"

    Overall length of just the choke tube (the part in the barrel) is 2.050"

    Widest diameter of the Breacher portion 1.007"

    Widest diameter of the choke tube is the threaded area 0.816"

    Hope this is helpful.

  3. I bought one of these off of E-Bay as I was looking for a comp that preforms better than the Tactical Solutions comp I have been using. The comp is well made and finished in a matte black anodize that matches well with the matte black finish of the Ruger 22/45 frame. The diameter of the comp was a perfect match to the diameter of my TacSol barrel.

    I took it to the range and shot it to compare to the TacSol comp. Using CCI Mini Mags the gun had less impact in the hand as compared to the TacSol comp and dot movement was less. With the TacSol comp the dot appears to oscillate a little and the dot dips below the target before coming back up. With the T-K comp the dot movement was straight up and came back down and stopped right back on target.

    For $31 I would call it a definite improvement over the TacSol comp.

    For $9.99 I also bought their hammer bushing that has a built in spacer to eliminate the magazine safety. It dropped in with no problems.

  4. I was not there so I cannot answer with certainty, but we can assume that since this was at a match the gun was probably modified and that may have had something to do with why it broke.

    Can someone explain the Browning A5 thing? If the barrel and mag tube are not connected by a clamp, how could the threads shear off on the extension nut simply from the barrel reciprocating back and forth during firing? I mean I can see it if they are connected, but if they aren't...how? There were likely MILLIONS of those A5's sold over the years and who knows how many of them were used for bird hunting of some type where you can shoot shells all day long. If that happened wouldn't there be some kind of history to point to of the same thing?

    Just curious. Please explain it if you don't mind.

  5. Has the Remington VersaMax became an equal to the Benelli M2 now? It seems as though there are an awful lot of shooters going with them rather than the Benelli M2's.

    Thanks for posting them.

    Equal to the M2? Not yet, I don't think. The M2 is still the top dog in shotguns but the VM is close, probably closer to the M2 than any other available shotgun on the market right now.

    I think we are in a great place when it comes to 3 gun shotguns. Less than 10 years ago your choices were either a Benelli or a Remington 1100. Now we have two guns from Benelli, FN, Browning, Beretta, Remington, Stoger, Winchester and Mossberg all offering guns that can be considered competitive.

    Edit to add CZ and Predator Tactical to that list.

  6. Personally I'd get a 20. Like a lot of things I have, things get shuffled around. It may be for a 3 gun rifle right now, but in the future I could use the mount for a longer range rifle.

    I would not buy the wrong mount for today's project in the hopes that it might be the right mount for tomorrows project.

  7. I have no problem with the senior match staff shooting the match for score. The only people whom I have ever seen complain about it are the same people who surprisingly (or not) I never see working matches. If there were any advantage to it at all you would see said shooters jumping at the chance to be match director, but you don't do you?

    As far as the prize table goes, again no problem. Running a match to win a prize would be stupid. You could get a part-time job, put in 25% of the hours spent working on the match and buy a prize equal to or better than the best prize on the table, and for a lot less hassle.

    I have not run matches in a very long time, but when I did it I had a simple attitude. Don't like the way I do it? Go shoot someplace else.

  8. Damned English system... Why didn't we convert to metric...

    Anyway the numbers don't seem to work out for me. What am I doing wrong?

    25 yards = 75 feet = 900 inches

    900 / 6.9 = 130.43

    900 / 7.3 = 123.29

    130.43 * 0.1 = 13.043 inches

    123.29 * 0.1 = 12.329 inches

    13.043 - 12.329 = 0.714 inch

    It seems that at 25 yards the difference will be almost 3/4 of an inch.

    You're right. I should never attempt math! In all my calculations I went 25 yards X 12 inches per yard, forgetting to convert to feet first.

  9. Not saying its not "better", because it is. If even by a little bit, it is measureably better - but what to do with that info? If I already had a gun that met my accuracy requirements, I'd spend that money on myself.

    Agreed. It's not an advantage you can use, but it is there, waiting to help you every once in a wile. And again, it has nothing to do with your accuracy requirements. Adding length to the sight radius does not make your gun more accurate. It makes your mistakes just a little bit less of a mistake. Every once in a wile it will make what would have been a C hit an A hit. A just missed plate becomes a hit plate. That hit that just touched the no-shoot will miss the no-shoot.

  10. So 6.9 inches of sight radius improved by another 0.4 inches would make a 7.3 inch sight radius...

    0.4 / 6.9 = .0579 = 5.79% less error in your sight pictures assuming you're shooting perfect sight pictures

    Ken,

    You're looking at it wrong. If you're shooting perfect sight pictures then sight radius is not important as all groups would be the same. If the gun is capable of shooting a 1.5" group at 25 yards and you shoot perfect sight pictures you will always achieve a 1.5" group, it doesn't matter if your sight radius is 1" or 20".

    What more sight radius does is give you less error when your sight picture is not perfect. Assume a sight alignment error of .10" low (half the height of a typical 1911 front sight) when the shot breaks. If your sight radius is 6.9" the bullet is off by .10" for every 6.9" traveled. With a 6.9" sight radius your shot will be 4.35" below your point of aim at 25 yards. With a sight radius of 7.3" inches it would be low by 4.11", 0.24" less.

    It seems like a very little difference but consider if your target is an 8" plate at 25 yards. 4.35" low misses the plate but 4.11" low catches the bottom edge of it. A minor, yet measurable difference. Or look at it this way, how many hits on paper have you had that just missed the higher scoring ring? Your 5.79% increase in accuracy (really a decrease in error) means that for the same sight picture every hit that was 3/4 of a bullet diameter away or less would have scored the higher zone.

  11. If we go by that thinking what would be considered "a safe manner"? Does the firearm need to be placed in a way that it does not move after the shooter places it in the provided location or barrel? Who is to say what is too fast or just safe enough? Where do you draw the line?

    I admit I abandon my gusn rather quickly as placing them nicely takes a lot of time. Granted if I am chucking guns in barrels as I run past they are completely unloaded.

    You are correct. The rule can be stated even simpler...

    "All firearms must be abandoned in the designated container, with the muzzle pointed down, or in the direction designated by the course description. The competitor must remain in control of the weapon until it is inside the designated container. Tossing or throwing a firearm is an unsafe act and will be grounds for a match DQ. Any discharge wile abandoning a firearm will be a match DQ."

  12. If the shooter places the gun in the receptical in a safe manner why penalize him or her at all?

    "All firearms must be abandoned in a safe manner, with the muzzle pointed down, or in the direction designated by the course description. The competitor must remain in control of the weapon until it is inside the designated container. Tossing or throwing a firearm is an unsafe act and will be grounds for a match DQ. Any discharge wile abandoning a firearm will be a match DQ."

    Do we really need more than that?

  13. I prefer the Remington Nitro 27's. 7 1/2 or 8's at 1235fps. I don't like hitting plates and not having them fall over. Every match seems to have a couple of targets that just won't go down to 1145's. If the stage or match is all clay targets then I use whatever 1145's I can get. The Federal Pink shells and Target load work well in my gun.

  14. It's all a matter of scale, and what people perceive as safe and the actions they feel comfortable around. My main point in this thread is that it is the act of abandonment that can be safe or unsafe, not the condition of the gun once abandonment has been achieved.

    An M&P or Glock laying in a dump barrel is no more safe that a 1911 laying there with the thumb safety off. I will agree that it is less 'unsafe' to throw a Glock or M&P than it is to throw a 1911 with the safeties off, but throwing a loaded handgun into a dump bucket is an unsafe act to begin with. It seems odd to me that we penalize based on the condition of the gun after the unsafe act, rather than the unsafe act itself.

  15. Errm - have you ever looked inside a 1911? The only passive safety in the original pre-80 design was the grip safety, which many competitors defeat by pinning, taping or internal grinding. The Colt Series 80 and Kimber add firing pin blocks, but these also are often removed due to the effect on trigger pull. Without a firing pin block, the 1911 firing pin is free floating and in principle able to hit the primer if dropped on the muzzle (even with safety engaged), The half-cock notch is a marginal safety feature at best.

    I may have seen the inside of one or two 1911's. You may believe the half-cock notch is marginal, but you're saying so does not make it true. The half-cock notch prevents the hammer from striking the firing pin if the trigger is not held to the rear wile the hammer falls. You are also incorrect in your statement that the firing pin of a 1911 is "free floating". An AR-15 has a free floating firing pin, the firing pin of a 1911 is spring loaded to the rear and the resistance of this spring must be overcome to fire the gun.
