IIRC my history correct, the very first AR's never had a forward assist. it was added after they had all th problems with the first AR's due to powder fouling and not being supplied with cleaning kits. they wouldn't chamber a round, so they added the forward assist to help chamber a round when it was filthy with powder deposits, so the soldier could keep firing, by just pushing the round into the chamber with the forward assist.

i think they are just a holdover from the fact they have been there for so many years now. i have never used mine either, but i do keep mine clean and oiled.

Yup..Feed issues in early AR rifles led to the addition of the FWD asst.

Yes the early fouling issues were the reason for the addition if the forward assist. Earlier rifles like the M1 Carbine, M1 Garand, and M14 had charging handles attached directly to the bolt carrier and worked as a forward assist if a round failed to go fully home. Happened every once in awhile with Garands when riding the bolt home to avoid getting the thumb smashed when charging with en bloc clips. A quick smack on the charging handle would correct the situation from trying to nanny it forward. The AR doesn't have that ability with the floating charging handle.

also the forward assist helps close the bolt quietly, or if you make a small brass check. i have used mine many times before. but in a failure like that in the video its not a good thing to assume it will help the situation.

Anytime you have to manually eject a round on any semi auto firearm, you should check the bore for an obstruction. Have had to do so twice. Once with reloads, no powder in the case(my fault, was reloading, wife distracted me, wound up skipping a round.), and once with factory ammo, (same thing, no powder). The primer on almost all ammo is strong enough to push the bullet into the bore.

that was my impression as well. i heard several times the rounds hitting the bench when he ejected the ones that didn't fire. the one that blew up might have been overcharged or the one before it was a squib load.

I have never in my 30+ years of shooting seen a squib in person until this weekend. We had our IL CCW class and I was helping on the firing line since we had 42 people to zip through . I was watching my end of the firing line and I heard a PSSSHHHHH two people down . The guy knew he had a malfunction and they were instructed in the class to stop and raise their hand if they had a malfunction and we would come assess the situation . I took his firearm , opened the cylinder and sure enough a big wad of wet powder just inside the bore and a .38 hunk of lead in the barrel about .75" up the barrel . Everyone was supposed to be using factory ammuntion and this guy decided to sneak in a few of his own rounds he hand reloaded back in 1978 ???? WTF . The instructor could have sent him packing but let him off the hook . IT really could have been a mess . The guy in the above video had someone looking over his shoulder several times . but if you continue to be a dumb ass what can you expect . If you have a issue like above with the AR it takes 10 seconds to push out the pin pull the BCG and give it a visual inspection . Stupid is as stupid does .
