AR TECH TRICKS 101!

Flex Hone

Don't jump the gun, Randall, patience is a virtue!!!! Actually, the one I'm going to show is much, much milder & less intrusive than a hone. No material removal here. Not that intense. Wait and see.

i don't know how changing the stock would mess with the receiver at all

Admittedly trolling for an argument is not how we see the forum running. Lay off or get time off those are your options.

you should read the whole thread i was the one attacked

An 800 grit flex hone does not really remove material either.
It just lays down the hairs and smoothes out the surface.

to smooth my chambers i just wrap a bit of 600 -800 wet dry
on a bore brush that fits the chamber a bit of 3 in one oil for micro chip removal

looks as shiny as a reloading die

You make 2 obviously negative comments and then say you were attacked when the OP requests you take it elsewhere? I am neither stupid nor blind. Quit trolling.

cool mod if you don't have extra lowers around. for some reason i always thought everyone owned 10 or 20 lowers? they are so cheap i know i'm not the only one.

[-hanko]

hmm is his next mod going to be a little pin to hold that in place?

Colt did use a cross pin to hold the buffer plunger in place.

On a 'go-to' weapon I try to avoid any mod that requires me to pack a special tool; an Allen wrench that fits a 4-40 setscrew is tiny (read easily lost). I just can't think of a field-expedient substitute for a tiny Allen wrench.

I've used Flex Hones, oiled crocus cloth with a cleaning patch loop, and 4/0 steel wool wrapped around a cleaning brush for chamber polishing. I've apparently missed another method

You could also show the fs post trick with an 8-32 setscrew that does away with the fs detent and spring.

The 1/20" is standard on all SAE hex wrench combo tools that you should either already have @ home & in your field kit, or that is available at virtually any hardware store. I must have six or seven of them lying around. In fact, the last one I got was purchased @ a 7-11.

Or you could.

I know 0.050" is a standard size, but...I want to try and keep my go-to gun and pack as light as possible, I don't envision needing to replace the stock in the field. To me that's more of a depot / get-back-to-camp kind of repair.

The fs thingy...remove the fs post, detent, and spring. Chase the fs hole with an 8-32 tap...thread until the tap comes out the bottom of the hole.
Install an 8-32 Allen setscrew from the bottom of the fs base. You can use it to lock the fs post in place.

Advantages?? If you're a target shooter and use an A1 round post, you have infinite elevation adjustment.

Down Sides?? It's faster to use the standard fs tool and you don't have to pack yet another Allen wrench.

Supersonic, great post and pics. Thanks

No, thank you!

hmm for more elevation adjustablity has anybody put more notches in the front sight post base?

file a mini flat tip screwdriver so it just barely fits corner to corner in the hex. you can also make any size hex wrench by hand with a fine file, and a careful hand. also, a trick i learned a while ago is to while at home with lots of tools, taper a allen wrench, imagine a 6 sided spike. then in the field all you need to do is grind it down, or break it off and rub it flush again on a rock or brick until the right size is reached.

in nevada at the area 52 shoot, one of the guys( i forget who) forgot long hex wrenches for his grip screw to change from mm grip to pg( the wrench didnt reach deep enough to install the pg with the hex bolt). i used a flat mini file (happened to be the right size to work like the screwdriver trick) and used plyers to twist it. basically whatever will fit and grip will work.

also, get a rubber slip on butt pad and hide extra wrenches in there. poke it thru the rubber in a way that it is not obtrucive and cannot fall out even if the pad is removed. ill take pics and post em if needed.

what about hiding a small spare tool kit under the hand guards? not to use often, just as a back up just in case? same principle as ziptieing a spare key under your car. not easy to get to but its there if you really really need it.

Supersonic..
Thanks for taking the time to take pictures and document this mod. Twice I have had to scramble and frantically look for the take-down pin detent spring. Both times I was changing over stocks when I traveled out of state.

I will be off to OSH shortly for a set screw.
