  1. I owe, an mark 18 sbr, an 11.3, 12.5, 13.7 pin and weld, and 16 inch rifles I run them all, most people will never be able to justify shooting out past 25 meters as self defense, shtf okay maybe, I say train and master your guns don't Matter the length

  2. Power of a 5.56 is not as good as several pistol rounds once you shorter the barrel to 10 to 16 inches. Keep in mind the bullet was designed to be effective when going fast. Slow it down and it is just a slow tiny bullet. 300 Blackout, or a 450 will perform better out of a short barrel. At close range I would use a 10 mm pistol over a short barrel 5.56. Ballistics don't lie.

  3. Due to the lovely infringements in my state, the shortest I can go is 12.5ish anyway (non-nfa "other" firearm >26in oal) at least I can get a taste of the shorty game until I move to a free state

  4. Whats the point or is it paranoia i have a adequate amount of weapons and reloading supplies and equipment my preferred is a 1990's sig p229 in 9mm 18 rounder yes 18rds. Next would be sar k245 14 rds and last ria mapp r9 hsms tcmr9 . Game over.

  5. I love my Iwi Zion ar pistol. That’s my go to home defense and do it all ar pistol. I love me some iwi guns. My iwi galil ace gen2 might be my favorite gun I have. I just need the iwi tavor for the trifecta

  6. 14.5 for me is good enough. Though a friend said you can pin and weld a 13.7 or maybe he said 13.9 , either way its legal rifle length and the velocity.

  7. M193 best with 20" barrels
    M855 best with 14.5" barrels
    MK262 best with 18" barrels
    These are where the cartridge has their most potential.
    10.3" barrels just lose velocity and accuracy over 100-150 yards and you start to get tumbling.

  8. Great news, my son Eric joined the Marine Reserves as an infantryman. He's at Parris Island as we speak. Graduation is October 1st. You're his inspiration. I'll keep ya posted from time to time. Take care. Love the premium content.
