I'm interested in what gun and ammo was used. You seem to know what is causing it and yet your solution is to use a Ti firing pin that equates to expensive snake oil. What ammo is/was it and who makes your AR?? I'm betting one or both of the aforementioned items are of questionable quality, or perhaps a damaged component of the rifle itself.
The "experts" on this forum often have a lot more germane knowledge than they let on. I won't list the very knowledgeable members as the list is quite long and not all of them have commented in this thread. What I can and will tell you, is that absolutely no one who carries an AR for a living or has carried an AR for a living recommends or uses a Ti firing pin.
As for sourcing one in Canada. Pretty much all the cool stuff you need to order out of the US as most vendors tend to carry junk, or have limited selections or are out of stock. For a rare and expensive snake oil piece such as the Ti firing pin, you'll need to do some digging and be prepared to spend a pretty penny.

The gun is a competition gun, not a "work" gun.
Has light weight bolt carrier and buffer, so the carrier velocity is faster than what you would typically find in an AR.
Everything is well within spec and high quality.
The ammo is Freedom Munitions. Seems their primer cups are thin enough that I'm getting intermittent doubling (3 or 4 per 100 rounds) in my main competition rifle.
That's unacceptable.
By reducing the mass of the floating firing pin, I'll be reducing the mass of the object slamming into the primer every time the gun cycles.
This
should eliminate the odd doubling I'm getting with this ammo.
If it does, I have ammo I can use in competition and don't have go spend $1000 to replace it.
If not, I'm out $40. I won't buy Starbucks for a few days and I'm no worse off.
In the competition world, Ti firing pins are a common remedy for this not uncommon problem.
Slamfire/doubling can be caused by a number of things:
- sticking/dirty firing pin
- bump firing
- improperly functioning disconnector/hammer follow
- primers too sensitive for AR use.
I know the cause of my issue, I'm trying the least expensive possible remedy first.
And to keep this thread on track, the results of the paternity test are back, and I'm NOT the father!
Woo Woo Woo Woo.
