    Plastic Muzzle Caps, what's your thoughts?

    While ordering some Colt 30 rd mags, I decided to add a few Plastic Muzzle Caps to the shopping cart.

    Well they arrived and are a lot tighter on an A2 flash hider than I expected.

    So what's your experience with these things. Are they a life saver for keeping debris out of the barrel or a pain in the butt?

    I thought I even read in the GI manual that the weapon could be fired with the cap on. I'm not going to be the first to try that though.

    BTW, ran 60 rds through my new 6920 today. S W E E T !

    EDIT:

    Well I just found this at http://www.quarterbore.com/ar15m16/ar15kaboom2.htm

    "Use the issue, shoot-through, plastic muzzle caps to keep sand and dirt out of weapon barrels. The $2,000 spent to replace five rifles could have bought 40,000 5-cent muzzle caps."

    "Note: Removal of the muzzle cap before firing is recommended. Place it in your pocket for future use. However, it is not dangerous to fire the rifle with the cap installed."

    An old foamy earplug stuck in the FH will do the same thing, and is just as harmless to shoot through.

    For most civilians, who keep guns in safes and/or cases, I think muzzle caps are kind of a waste of effort. Nice idea, but doesn't buy you much.
    Principles matter.

    They certainly kept our bores clean during Desert Storm, as well as during training FTXs. Never had the opportunity to shoot through one though, always wondered about that one myself.....LOL.

    The GI muzzle caps can be fired through without hazard to the gun or significant deviation in POI. If you're using them on a cased, racked, or stored gun, make sure you remove the cap from time to time to check for corrosion. The cap traps moisture. The ear plug idea works to protect the bore from debris, and also keeps the air moving through the FH. A bag of balloons from the party or dollar store work, too, and are cheaper than the caps. Same caution applies for the moisture.

    Duct tape works as well. Cheaper too.

    Caps were designed to be shot off. They were nice to have when doing patrols during the rain, as it prevented the mud getting in the muzzle when falling in canals

    For weapons that had no muzzle caps, we improvised with speed tape.





    Muzzle cap is hard to see here in this pic, but my improvised M203 cap can be seen.

    Yep, that's what they say.

    I did the same thing. Using the yellow foam ear plugs while in desert environments, for my pistol and/or rifle, back in the day.

    Saw about 1000 "shot through" by accident at ranges, and had to shoot through one of mine for real while returning fire on some jackasses in Mahmudiyah. Great piece of gear.
