That little detent likes to shoot all over the damn place. Fired across the room a couple of times, lucky to find it in the end. Just ordered mine lol

I paid $.50 for mine. 1/4"x2" clevis pin from the hardware store.

Ohhh interesting... might have to swing by Home Depot tomorrow.

I would have paid 4 bucks for one when I was building mine. That front sprint/detent/pin sucks ass to put in. At least it did for me.

I used a 3/16" Allen wrench on mine.

Nice thing about the clevis pin is you can drop the spring then the detention down the clevis hole, a short push with a thin Allen and a 1/4 twist makes everything too easy.

Hell yes! Thanks for showing me that trick. It works like a champ.

It's not that difficult installing them.

[VaderTT]

Never had an issue, although I could see why.

Word. I've put together 4 using a razor to hold it in, no issues.

I just use a razor blade, never had a problem.
