Broke my bolt catch over the weekend, dumped it out and kept shooting then went home and ordered an armalite catch. This was part of a cheap parts lot and I wasn't surprised. Checked the hardness of this and was surprised it was 52 Rockwell all the way through, no wonder why it broke. O well.

I sense a four letter word...

I purposely didnt say it because of you! 

 

 

How do you test hardness? I always see the rating but have no idea how you check.

We use a tester at work that pushes a diamond into the steel and measures hardness

Was wondering what that was. Tom keeps one in his range bag. That guy is always ready for anything.

 

Stuff that in your gunshot wound, brother, and it'll staunch the bleeding REAL quick!...   <lmao>

 Wonder if that part was made with the Metal powder forming process ? What ever you call it .

 

seems to be, but I know nothing about that stuff...

Man...if you got quarters to stuff in the RE, you should've spent them on higher quality parts.

If I have to feed it quarters I'd better get a pop and a candy bar.

Holy crapperoony.  Somebody says hard, a dildo pic appears, and the cheap-ass parts thread is FUBAR.  Yuk!  

 

So was that a CMMG dildo-hardness-tester thingee?   <lmao>

I had no idea CMMG built trains....

He means to imply this thread has derailed like a mother*ucker :banana:  which is what this place is best at, before you know it it will be 6 pages long and there will be numerous sexual references to double headed dongs and tootsie rolls <laughs>
