MagPul is an excellent brand with high quality control. Make sure you keep your magazines clean and your rounds clean; if you put lube on the magazine port then extract the magazine it will gum things up. They work best when dry. Next, make sure you don't pack your magazine full of rounds -- IOW, if it is a 30-round, push in 27 rounds; always leave the spring room to breathe. If you use a rotary 100-round magaine as I have for my SKS, don't turn the wind-up handle tight; just keep a little tension on it until it is time to really let loose. And very importantly, make sure your last 3 rounds in the magazine are tracers so you know when to get ready to get ready and pull the mag for a quick change. Oh yeah, and have that second magazine really ready for a quick change too, not stuck in your back pocket or back pack or up your ass-crack where you cant get to it very very quickly. Points to remember: 1. Load ammo into the magazines with either cotton or nitrile gloves so there are no fingerprints on the ejected cases or the rounds which will be injected into targets (niggers, politicians, etc and (((judenscheiss))) ... ) Just saying, think OPSEC and don't dox yourself right off of the first round you fire. 2. Don't drop your empty magazines; aside from the fact that a good one is expensive, dropping will damage the feeder fingers. You will for sure need them later (to reload) when the first run of 50 or so niggers have eviscerated by hollow-points on the front lawn. Remember to handle the magazines with nitriel or cotton gloves so as to avoid finger prints. 3. Vary your ammunition; don't rely entirely upon one specific brand or vendor. First, it is bad OPSEC to buy lots of ammo from the same place and the same brand. Second, Nameless East European or Chink ammo almost always works for close firefights and can't usually be traced. I know, in a firefight you want "reliability" -- but you are not shooting the National Matches at Camp Perry, only killing bandits, (((jews))), niggers, etc 4. Watch where your tracers go (last 3 rounds in mag, remember?); they will for sure catch something on fire wherever they land unless it is inside a nigger, (((jew))), etc., etc., et. al. 5. Keep your fire rate down to a short burst of 1, 2, or 3 rounds if firing on full auto; even when faced with a crowd of 50 thieving niggers on your lawn, aimed quick fire is always better than "spray and pray". This goes double for long guns with heavy recoil such as a .30 caliber or larger. 6. Always have a back up plan in case your primary weapon fucks up in some way or another; know how to quickly clear your weapon, but if -- for example -- a round gets jammed inside the suppressor -- know ahead of time what you will do. Fire another round to clear it? Unscrew the suppressor? Sling the weapon over your arm and raise your back up long gun? Run?
