Heirloom, Doping used to be called Kentucky Windage because there was nothing to dope but the shooter, and his view of the target!!! Wind always came into play, if it was blowing a little to the left, you compensated by aiming a little more to the right!!! This is how My Father /Uncles taught us how to shoot, works well if you have a steady aim, and Know your Rifle!!! I prefer shooting with an iron sight, more reliable in Combat. I have Red ots on just about all my Rifles, Aimpoints, Trijicons(THE BEST IN MY EXPERIENCE) but Aimpoint and EOTECH are close seconds. I also have Bushmaster Red Dots(MINI) on my AK-74. My M-4 is set up with a Trijicon Red Dot Scope Combo, built into the whole Trijicon Unit. It is also semi night vision grade as well. Doping it is easy, Usually no misses out to 300 yds, 500yds is really pushing it, but I really would not go shooting at someone 5 football fields away, unless they had just done in My Family, with a 5.56 round!!! I would get out my M-14 for that, Iron Sights Only, if I had time, otherwise I would be chasing that SOB till I got them!!! The Bullet Buttons I am talking about are not for Pistols, but what the Politicians(DEMOCRATS), call Evil Assault Rifles. They are not magnet and look and work just like regular Mag-Releases, it's just that You need something Pointy to insert into the hole to remove the Mag, Hence the name Bullet Button. They have come up with many clever tricks for the ones that go on M-4,M-i6's. A ring made of plastic, that has the Pointy thing built into it, so you can just shoot till empty, and reload almost Normally. There is also one I just got that you can adjust for CA, and unadjust with the turn of a Copper L shaped bar, that turns it right back into a regular Mag Release Button, needless to say, i do not keep my M-4 adjusted for CA. Stupid Ridiculous Laws!!! If everyone would right into their Congressman and say enough is enough, maybe some of these Socialist/Marxist/NAZI laws would be thrown out. Senator Yee has added many new stipulations to an Agricultural Bill called SB-249, that want s to get rid of our Bullet Buttons as well; it just passed the Committee for a real vote, we need this not to happen, or they will be confiscating our guns and bullet buttons, with no monetary compensation!!! That is just wrong, I love the way they turn an agricultural Bill into a anti Gun Bill, and get away with it, because the farmers need the Bill for Water, ETC. Yee is a proven anti gun lobbyist, I dislike his political agenda, and that was sneaky and smart to put it into a Bill almost Guaranteed to pass as Law, Because our agriculture needs it, sneaky Bastard!!!! They will not get My Guns, I'll rent a storage space in some other State, and put my Weapons(ASSAULT RIFLES) There. Or just refuse to comply, I have put so much Money into my Guns for extras, like Red Dots, Lasers, Night Lights, that I cannot afford to just give the Weapons away!!! Maybe it will be found to be Un-Constitutional!!! I would rather keep My weapons(SOMETIMES,USUALLY) than to even go on growing, I believe in the 2nd Amendment 1000%!!! Am A Life MEMBER of the NRA. All my pistols, but my Kimber UC have 10 round Magazines. I also(OF COURSE) am a CCW Holder. So Heirloom recheck out what i told you about, I guess I was not clear enough. Anyso called Assault Rifle that can hve a bullet button, can be legally sold in California for NOW. really check this out, you could own an M-4gery in 2 weeks, providing You can pass all the background tests, and it sounds like you can!!! SINCERELY, JAMESTHEGREEN.
