Best way to seal up a charging handle slot from dirt ingress?

This is basically asking about the pros and cons of a sliding dust cover like the FN FNC or M249/Minimi vs a gasket like what the FN CAL and Sig 550 have. I know that both work given those weapons reliability records (at least mil-spec FNCs and 550s), which do you think is better?

Well, since the ejection port in a FAL is much bigger and always open ( at least to the carrier and rails ) whereas the charging handle slot is way smaller and closed 99% of the time, my personal opinion is why bother ? To my knowledge, at least, it was never identified as a problem in military service, so I would think in our kinder, gentler civilian hands and environment it is even less of an issue.

A non issue, JMHO.

I’d watch the whole thing, but if you are impatient skip to the 3:50 mark. Not FAL, but the principle holds true.

The Israelis came up with a dust cover for their heavy barreled FALO. Not sure how well they worked. They are fairly rare and hard to find for sale. The will fit on any FAL, IIRC.

As a side note, AFAIK the Israelis never officially adopted the cover, as they phased out the FALO pretty early on. Mechanically they seem to work fine, can't vouch for how effective or durable they would be in the field.

I have a couple of these covers - while they will work on standard FALs, the carry handle needs to be removed as it interferes with the cover when folded if in place.

I think port covers are overrated unless you are in a dust storm, which isnt likely to happen in most of Europe or the US.

I'm curious why the Israelis supposedly had huge trouble with the FAL in a sandy / dusty environment, but none of the Commonwealth or African users did. Did the L1A1 ever let the British down in Yemen, Oman, or Iraq?

I remember at the time rumors were going around that the Israeli troops were not cleaning and maintaining their rifles well, but that is strictly hearsay, and I find it a little difficult to believe. I'm not even sure that the claims that they had reliability issues were true at all. I think the biggest reason they retired the FAL was the universal shift to 5.56x45 and the tons of M16s we sent them as aid.

This is from memory, but I seem to recall that the Brits found that the FAL/L1A1 was sensitive to specific kinds of sand, primarily the very fine, dustlike type. Other than that, no problemo. Of course, they also said that the sand cut carriers and receivers worked best when glommed up with grease, which supposedly captured the sand and prevented it from causing malfs. Seems like a good recipe for grinding compound to me, but what do I know ? I'm not sure that recommendation was ever actually mandated in the field. Someone here with real world experience will probably chime in to set this straight.

I was wondering mostly about the sliding cover on the FNC over the charging handle slot vs the gasket that the Sig 550 and CAL have. I wonder if a combination of both systems where tried.

naw, just squirt some red RTV silicon in there and you'll be all sealed up.

My charging handle slot is covered by the charging handle unless it is in use to charge the rifle. Not sure what you need a cover for since the handle locks forward for use and does not reciprocate when firing.

... this, the question appears to be a solution search of a problem. Fine fine red dirt/dust is prevalent in probably 2/3 of the country, that stuff gets into and everywhere. The SLR was not know as being susceptible to it in use. Good cleaning regimes are important or course. The big honking ejection port is more of an avenue in of course (as noted above) than the charging handle slot.

I’ve never been a soldier where my life depended on the function of the gun. I never understood the lack of cleaning aspect that is prevalent in most of the functionality lore. Wouldn’t cleaning your stick with an oily rag be pretty much a routine every chance you had if you’re in an active combat situation?

Agreed - it's kind of like wanting to seal off the magwell.........
