Sometime last fall
I was at a customer who was experimenting with some way to tie his charging handle to the BCG in his rifle.
This was one of the older rifles without the forward assist, and he was convinced that connecting those two items was the answer to his troubles.
I was going to suggest a new upper and BCG, but I was then and am now an AR newbie, so I wasn’t going to comment.
Sure enough, I ran into him today, and he had a big scar across his cheek. Guess you don’t have to be too smart to know when not to be a dumbass.

Some people have an underdeveloped sense of when to kick the good idea fairy’s ass.
I learned years ago to listen to that Little Voice whispering at me that perhaps this isn’t the brightest idea I’ve ever had.
That little fkr is rarely wrong.
“Do I know more about this firearm than Eugene Stoner did when he designed it*?
No?
Right.”
(* Or the people at Colt’s when they turned it from the AR-10 to the AR-15.)
Let me guess…this is not one of your brightest customers?
For dedicated high power match rifles we would slot the upper and install a knob on the bolt carrier so a fixed cheek rest could be used and still be able to retract the bolt. On my service rifles I fashioned silicon “seals” on the charging handle to keep the little bit of crud that sometimes makes its way out of the upper past the gap between the handle and upper. Most folks never notice it but if you are laying on the rifle prone for a lot of shots and your face is close to the rear sight it can irritate your favorite orb. It did seem that some rifles were more prone to this than others, maybe tolerance stack in the BCG?
Blind: I’ve seen that little silicone bit you’re talking about, and i kinda understand how it would work. I also wonder if there’s something about tightness that changes the amount of blowby.
My dedicated target rifle also doesn’t have a forward assist, or a dust cover. (you may recall my project to switch uppers a while back) I don’t have any problems with it that need fixing.
BTW, backing the diopter on my scope all the way out gives me about 1″ less eye relief. The manufacturers webpage says I should have about 3.75″ of relief. Backed all the way out, I get right at 4″. It was 5″ with the diopter all the way in. I do get some loss of focus on the crosshairs, but not too bad.
We’ll see how that works this weekend.

Be sure to check your parallax.
Og, the mind boggles….
Og, I made the charging handle seal with black automotive RTV.
I just refilled my parallax from a fresh bottle last week, so it should still be good.
It was designed without a forward assist so why fret about it. The FA was added as a crutch to get over the dirty chamber problem when DOD cheaped out over the powder and cost a lot of soldiers and marines their lives.
If it is short stroking or moving too fast to reliably pick up a round from the magazine, an M16-style BCG is heavier and should slow the works down as needed.
