If you have an AR-type rifle with a standard flash suppressor on it, and you store it outside of a case as in a rack, and place a plastic dust cover over the flash suppressor, what happens if, in an emergent situation, you grab it, stick a mag in it, rack it and go "hunting", and (God forbid!) fire it, forgetting to remove the dust cap? Anything bad?
I can’t speak from experience but I’m sure you get a hole in the dust cover. Thank me later.
It depends on what you mean by “plastic dust cover”.
If you’re talking about putting a piece of Saran Wrap over the muzzle, the bullet won’t even notice.
Why have the dust cap? In a humid environment and a dry (oil free) rifle, it'll rust like nobody' business. Dust doesn't have any effect on the flash suppressor or the bore of the Mouse Gun.
If you’re concerned, take a cover with you the next time you go to the range, and see if it changes the point of impact.
I put condoms over the ends of my barrel, then put them in the rack.
Great conversation starters!
Just gets blown off.
I like your sister, she’s hot but, the like plastic thingy is going to fly forward at 3000fps and you continue firing...
Pops a hole right thru it. We did it all the time in Iraq.
I think your dust covers are weird. I agree that you really aren’t protecting anything. If your rack is open straight to the ceiling just but a board, a few inches over the whole rack. Or throw a sowing thimble over it or if its bigger, a shot glass. This is Wisconsin, right?
It was 100 push ups if your dust cap went down range on the first shot. Then you had to go find it and wear it around your neck for a week. With a little 5.56mm hole in it.
During WWII, it was reported that GIs would place a condom over the barrel of their rifle for the same reason, to keep mud and dirt out. You could still shoot with no problems.
Be careful about those dust covers trapping in moisture in a humid environment. Over long periods it can be a problem.
Spent over 13 years working part-time for a small dealership that also performed gun repair. Encountered dozens and dozens of owners who put a piece of transparent tape over the muzzle before going afield, to keep out rainwater or snow. And insects that might find a gun bore to be a good place to lay eggs - such as mud-dauber wasps.
On firing, the bullet compresses the column of air ahead of it in the bore so violently that it typically blows off the tape, or a plastic muzzle cap.
Any material inside the bore can cause a very different outcome. Even the slightest constriction can interfere with the bullet - resulting in a bulged barrel, or even a burst muzzle. Can occur even of the blockage is minor, such as snow pushed into the muzzle by accident, when the owner moved about the terrain or crossed a fence.
A couple times, we found a shotgun muzzle to have burst because the screw-in choke tube was not screwed all the way in. Nearly as we could determine, that is; on another occasion, we estimated that the reaming and thread-tapping for the choke tube had been accomplished in a sloppy manner, so a portion of its rear lip stuck out from the wall of the barrel and caught the shot cup as it went past.
Keep your choke tubes screwed in snugly: finger-tight only (the wrenches are for removal, not installation). Check them before each field excursion. And keep the threads of the tube and the bore well lubricated with tube lubricant.
Hire a maid to eliminate the dust problem.
Cling Film, plastic wrap, sandwich wrap, or what is commonly called “Saran Wrap.” I use it to cover optics etc... keeps the dust down. But in the field a condom works good. Except in sandy environments (because sand gets everywhere)...
