Good Evening everyone! This is my first post and I have a question regarding the 7.62x39.
I have done a good deal of .556 builds but am new to the 7.62. I am a little worried about the A2 front sight block on the 7.62 barrel and was hoping to get some reassurance. The barrel at the gas block is .750 and the bore is .300 which leaves (.450 total) .225 on either side of the bore . When I measure the gas block taper pin from the inside bottom of the gas block to the top of the taper pin is .185. What I am worried about is that leaves only .40 to the bore. Is this enough material between the bore and the pin to be safe? Thank you so much for your collective help in advance and I look forward to becoming an active member of the forum! Thanks again! |

Thanks so much for the replies! Jaqufrost yes Sir it's already mated.
The part I am worded about is where you say.... Quoted: if its already mated, then I would just use it until failure. How big a failure are we talking about here hahaha barrel and gas block fragments forced into parts on my person type of faliure doesn't seem fun hahah. Thanks again and take care! |

If it failed it would probably vent gas out of the bottom of your barrel. The rifle would probably still cycle for a bit, but I wouldn't want to have my hand directly under the front sight when it vented. Given the steel pin behind the thin barrel section it might run 10,000 rounds without failing. |
