    • @Tier1Citizen
      @Tier1Citizen  8 днів тому +1

      M193 is my choice for carry ammo. Lightweight means more velocity out of a set up that is already lacking in speed. However, once you get into the lightweight ammunition, like 45 grain TSX, you are causing the rifle to extract too quickly and you will probably end up with malfunctions. That's why I stick with M193.

      I'm sorry to have to tell you this, but yes, piston guns don't age well. There is a reason that most ranges that rent machine guns don't run piston guns. They run direct impingement guns instead.
      The greatest lie told to the AR-15 industry was told by H&K, back when they released the HK416. They said "the AR-15 has finally been fixed..." Those of us who build AR-15's went "what, since when is the AR-15 broken?" The AR-15 is way too high pressure to run on pistons. That is why op rods crack and or bend and strike keys fail. AR-15's were meant to run on DI systems and AK's were meant to run on pistons. The two should never cross paths.

      This is my opinion based on anecdotal experience. The sight radius is too arrow on something like this for it to be useful for anything other than a gross sight picture. This is similar to the sights that came on the top of the Trijicon: ACOG TA01NSN www.trijicon.com/products/details/ta01nsn
      In theory it's great, in execution it is nothing more than a very loose way of knowingly, roughly, which direction your weapon is pointed. You can do the same by looking through a dead optic and bracketing the front sight post, or even your raised thumb inside the optic, and pulling the trigger.

      This one Spikes is heavier is you need to go there. Your casings should be ejecting around the 3 - 4 o'clock positions. Antying forward of the 3 is too much gas. Spikes T-2: aimsurplus.com/products/spikes-tactical-st-heavy-buffer-t3-5-5-oz
