Titanium firing pin - LOL! :)

[1168]

Whats the rationale on each of those things? We normally include that in this subforum.

[HKGuns]

I question whether or not the bolt is actually an upgrade.

I would dump the one piece gas ring setup as well as the Ti firing pin.

I didn't see a single thing on that list I would put on or replace on any of my Colt M4s, dont take offense, you chose to cast your pearls before the swine. Your gun, if it makes you happy.

Will Do ! Thanks

[Leaveammoforme]

Wow! Nice upgrades! It's nice to see someone who knows how to get it done.

I'll give you $100 for the complete junky Colt BCG, action spring, buffer, A2 grip, charging handle and the fire control parts that you removed. I have a loaner I'm building and the low quality parts won't matter.

You can get an awesome looking muzzle device with the $100 to complete that sweet rifle.

[RedTeam98]

your right I have my sights on a SureFire muzzle device .
I was thinking about the SureFire Pro Comp.

[JediGuy]

I’ll do $125.

Regarding the muzzle device, I used and liked the Warcomp, only changing in preparation for a mixed-caliber suppressor purchase.
With that said, if you plan to suppress, note that Pew Science has found the Warcomp to be detrimental for sound suppression. Just as info. The flash hider (if unsuppressed) or brake (if suppressed) may be better options for you.

I want the Colt gas tube...

Troll post?

I would dump the one piece gas ring setup as well as the Ti firing pin.
In an AR, the firing pin is a direct contact pin, ie, when the hammer pushes the FP forward it maintains contact through indenting the primer. So, a lighter FP won't make any difference.

Lighter FP can only be a problem with inertial firing pins, like a 1911, where the momentum of the FP is the only source of energy for primer ignition.

[RedTeam98]

The full force SSA-E hammer spring when teamed up with the lighter Titanium Firing pin provides very fast lock time
And excellent performance same setup I have on my MK 12 also.
The AR also has floating firing pin that does not make contact with the primer until the hammer falls.
My AR-15 Firing Pin is made from Grade 6 Titanium. E Series is the standard pin with only one step. 0.015 Longer Firing Pin for reliability on cheap Ammo. If I remember right the original M16 had a Titanium Firing pin but production cost switched to cheaper steel firing pins.

I was thinking about it from a strength and elasticity aspect, not weight or functionality.

Ok
It’s a great combo setup SSA-E trigger and Titanium Firing pin. Try it !

Fairly obvious you do not understand how the firing pin and hammer work together, OR what 'lock time' is, OR what range of FP protrusion you really need or should have.

You got screwed and bought really expensive snake oil due to the lack of understanding...


1) About your floating firing pin 'not making contact with the primer until the hammer falls' - What happens if you load a round and then eject it without pulling the trigger? Look really close at your primer and tell us what you see... What made that dimple right where the firing pin would have touched it if the hammer never fell???

2) Lock time - As lysander said "when the hammer pushes the FP forward it maintains contact through indenting the primer". Being lighter will not change anything with respect to 'lock time'. Will not do jack squat except lighten your wallet...

3) FP Protrusion - A wise person measures what he has before adjusting or replacing parts to get more. You could have (if it was needed) increased the FP Protrusion you had on your Colt firing pin that you had in seconds with stuff you likely had already there at your home.

Uhhhh, . . . . no.

To speed up the lock time on a AR you need a) and stiffer spring, b) a lighter hammer, or c) both.

A lighter firing pin only speeds up lock time in a striker fired design, or an inertial firing pin design.

An additional 0.015" would give you a firing pin protrusion of 0.051" or a recipe for pierced primers.

And, no, the original M16 did not have a titanium firing pin.

BTW Grade 6 titanium is not all that special . . .

This one is going just how I thought it would.

I hope you kept your stock parts.

On a working carbine, the only thing I add is a detachable WML.

SSA-E is my a standard trigger so I may just try it on one rifle to see if I notice a difference.

Good choice on trigger !
Remember don’t dry fire a SSA-E it’s a full force hammer spring !
It could damage your lower.

Only if you dry fire with the complete upper not attached to the lower.
The hammer is stopped by the firing pin before it can contact the lower receiver normally.
Dry firing damaging the lower receiver is a potential problem with ANY hammer spring if done with the upper receiver pivoted up or not attached to lower, hence there are plastic blockers that sit in the magwell to
take the hammer hit when testing FCG with an open carbine.

Actually, if you look closely at a lower with the hammer down, the hammer cannot contact the aluminum receiver. It is stopped by the bolt catch.

Dropping the hammer on a lower without the upper with BCG can damage the bolt catch pin, the pin holes and the forward face of the bolt catch slot.

[mpom]

Not arguing w Lysander who probably forgot more about the AR system than I ever learned, but since the bolt catch pin holes and bolt catch slot are part of the lower receiver....

[lysander]

Not saying you aren't going to damage the lower, just pointing out what gets damaged

[Hammer_Man]

This thread cracks me up:laugh:

[1_click_off]

Did you change your grip screw? If so, did you re-use the washer or go aftermarket on that as well?

[RedTeam98]

Grip screw washer
Yes I Reused the washer !
if they make a better one sure will !
Thanks

I will do $150 and add in some C Products mags

It might take away from the Ukrainian threads..

Send me a SureFire Socom 5.56 muzzle brake and it’s a deal !

Thanks to PUTIN the price of whatever lube he says is best is definitely going up.

GET IT NOW...

Go juice

I prefer the grease.... go juice is OK, but I find myself using Slip EWL 2000

I highly recommend Nu-Finish on those parts exposed to the sun.:rolleyes:
