Do any of you guys have any experience with DDI's new American made forged bolt and bolt carrier? I just ordered one of their rifles and was concerned the G2 fcg might cause the rear of the carrier to mushroom. I was thinking of dropping in an ALG AK Trigger to try and avoid the chance of this happening all together. Thanks in advance for any info, much appreciated.

Why are you concerned that the G2 FCG will cause the BCG to hit the rear trunnion? I have not had that issue with the G2 in any of my AKs. If you are worried about the hammer being profiled so low that it does not provide enough friction to slow down the carrier before it hits the rear trunnion, I would think that that problem would present itself long before that in not pushing the hammer down far enough to reset the trigger.

I have had absolutely zero issues with the G2, and I have modified forms of them in Saigas of all calibers, Yugos, Romanians, VEPRs, and Norincos. I would not expect any problems with them in DDI or other US manufacturers, unless of course they have deviated from a proven design.

I'm not worried about the carrier hitting the rear trunion, Tapco G2 fcg's are harder than milspec and the hammer isnt the right shape either, thus some carriers made of softer metal or that weren't properly heat treated have a propensity to mushroom out from repeatedly hitting the hammer.

Generally speaking in most cases the tail of the trunnion usually deforms and mushrooms to a certain point and then it quits.  It almost never really causes performance issues.  Is it a cosmetic issue?  Probably.  Does it really matter?  If you want a safe-queen rifle maybe.

 

You can always grind a G2 in to the geometry that you want if you think that will help.

I wouldn't worry about it. Even if the rear of the carrier mushrooms a bit, it will likely only do it to a certain extent until the steel work hardens.

So I picked up my new DDI AK47S and upon inspection it looks like there is a small crack is the gas block under the paint, anyone have experience with something like this?

Looks quality.

 

Did you contact DDI? I'd start there if you haven't.

I did contact and they got right back to me, they said it was a casting mark, not a crack. Does that sound legit?

It's possible.

You have it documented now by contacting them.

Use it, if something breaks, contact them again.
