Trigger guard OCD problems.

[din]

Can anyone tell me which alloy the Knight's trigger guards are made from? I know this is completely ridiculous, but I bought a B5 trigger guard, and I can't bring myself to use it as it's milled out of 6061.

[Stone]

Probably the same as the B5. So you cant use it because its made out of aluminum?

[WHSmithIV]

There isn't a great deal of difference between 6061 and 7075 aluminum. 6061 is excellent general purpose aluminum and a trigger guard certainly doesn't take a lot of stress. Here is the 6061 alloy composition:

Silicon minimum 0.4%, maximum 0.8% by weight
Iron no minimum, maximum 0.70%
Copper minimum 0.15%, maximum 0.40%
Manganese no minimum, maximum 0.15%
Magnesium minimum 0.8%, maximum 1.2%
Chromium minimum 0.04%, maximum 0.35%
Zinc no minimum, maximum 0.25%
Titanium no minimum, maximum 0.15%
Other elements no more than 0.05% each, 0.15% total
Remainder Aluminium (95.85%–98.56%)

7075 aluminum is a stronger alloy than 6061 mainly because it has between 5.5 and 6% zinc in it. It also has up to 1.6% copper and up to 2.5% magnesium.

7075 aluminum comes in 5 different sub alloys with the strongest ones being T7 and T651.

I used to work in an aluminum extrusion plant.

I can't use it because I'm being type A about this build to a degree that makes those folks who wash their hands 300 times a day look normal. I know the differences are pretty much academic for such a small part that doesn't see much stress, but the heart wants what it wants.

Who even makes a 7075 trigger guard?

[din]

Also, Will, you are awesome, thanks.

[GOST]

I'd say you're gonna have to contact KAC to see if it's 7075 or 6061. But be warned that your email will probably be forwarded for laughs followed by expletives. Odds are though the only 7075 trigger guards are integral on billet lowers.

And here i thought i had OCD bad......lol....[:D]

Aero Precision 7075 Trigger Guard https://aeroprecisionusa.com/aspx/store/productdetail.aspx?pid=305

Now you can save yourself a (possibly) humiliating email to Knight's. [BD]

[GOST]

There you go, Deadwing to the rescue.

[tact]

And then there's this guy that uses polymer trigger guards on everything......

[velocity2006]

I have had a few lowers with the Magpul polymer trigger guard that were ran very hard and never had an issue. If you're that concerned go titanium.

A 50$ trigger guard? That's flashy.

A 50$ trigger guard? That's flashy.
Yeah but it has holes.

[Dstrbdmedic167]

I've got some magpul trigger guards I'll be sure to send you guys. [BD]

mind -----> blown

[WHSmithIV]

Also, Will, you are awesome, thanks.


I just like to be helpful Din. I'm sure someone will be able to use that B5 trigger guard you have so it won't go to waste too.

Good luck! At least you can get the Aero Precision one and it will keep your mind at ease and it's only $20 or so.

[SINNER]

You have got to be kidding me.....

You have got to be kidding me.....

[:D]

[Aragorn]

So did you get the Aero or the Hoplite? If you're gonna obsess, I mean, WEVO could use some pics of a Titanium trigger guard. :P

...Maybe even a review. Not like you see a lot of trigger guard reviews. [BD]

[WHSmithIV]

I found a couple more for you:

Brownells has this one - I like it - no roll pins:

[Stone]

Put that rifle back in the safe and lets call it a day.[bash]

[din]

As much as I like Ti, that is ridiculous. I thought about the Dead On guard already, but I heard they can rattle a bit. I just like my alloys to match, but I may just stick with the B5. Or the Knight's. Or flip a coin and pick that way.

[GOST]

Just pick one because this thread desperately needs to pass on.

[Dstrbdmedic167]

Just pick one because this thread desperately needs to pass on.

Says the pickle master...

[GOST]

Yes but the pickles are discussed in the Lounge.

[din]

I'll bump this thread in six months after I've made up my mind.

[WHSmithIV]

I'll bump this thread in six months after I've made up my mind.

Well Din, at least you now have at least 2 decent ones to choose from in 7075 - the Aero Precision and the one from Brownells [:)]

[Eric]

I'll bump this thread in six months after I've made up my mind. Or not because this is ridiculous and done.
