Smyth Busters: Does Your AR-15 Need Anti-Walk Pins?

[gassprint1]

Yea, atleast 1 does.

Haha, I've got one of those too.
Cheap drill bits.

 

[OneBadV8]

I mean, it doesn’t need 30 rnd mags either

I dont know if the channels the trigger spring legs ride in aren't groved wide or deep enough or what. Haven't really looked into it much. The lpk is from that place in Middlebury from 10 years ago before atf shut them down. All milspec stuff.

 

[cosermann]

Context matters? Huh, imagine that.

A cassette vs. 2-piece trigger would be an interesting video too. There are pros and cons to each.

The pins are designed to rotate freely. Anti-walk pins prevent this and the product should not exist. If your rifle needs anti-walk pins, something is not in spec and should be corrected, not bandaided.

Mine was from a drill bit that wandered, even though it was guided by a jig, IIRC. Had to make the hole bigger to achieve alignment, then needed to secure the pin and hide the hole.
As others have said, out of spec.

From my understanding, the anti-walk pins are suppose to rotate when installed. Screws are supposed to tighten against pin and not the sides of the lower.

I’m not an expert by any means, but to my understanding, even the ones that do end up floating have a larger rotating mass and provide inconsistencies of the 1/4 turn of the hammer pin, which controls lock up timing. This can create light primer strikes and on the cheapest ones galling, which introduces drag into the rotation. Ultimately to me, it comes down the fact that there is no need for the product to exist with proper in-spec LPK. But that’s just me.

Can we put him in time out?

 

[OneBadV8]

Can we put him in time out?

I mean, I have anti walk pins but I know full well they’re not needed

 

[DadSmith]

Don't those encased FCG's require them?

 

[gassprint1]

I watched video and i thought they said the drop-in fcg came with pins and i dont think they rotate either.

 

[Karl-just-Karl]

In the case of Timney trigger groups, there are set screws in the sides of the cartridge that push against the bottom of the receiver. Once properly tensioned, I have had no problems with the pins coming out. The pins are held in place with shear force.

Well, we have Joe Biden too, and everyone knows full well he's not needed, but we have him anyway.
My next crusade, Impeach anti-walk pins!

That video have me a headache. WTH was he slurping out of that coffee cup, must’ve been pretty good.
