I tried to translate the last bit of real info on what to do i took some liberties in rewriting it i hope it helps
"I remembered that on the old automags (if you remember that 2pts old-school-ism ) they had put a dense foam part in front of the bolt to soften the impact. On my Angel 1 it is the same concept, they put a thin part of soft plastic, this is the part which touches the ball at the time of impact. Thus what I am trying to say... why not take a bolt of X-7 (or A-5 even thing) and put such a material to reduce the violence of impact on the ball? 1st I wanted to put a type of foam but I did not succeed. My 2nd idea was simply to put a O-ring at the end of the bolt. I went to Rona (Home Depot - etc) with my bolt in hand and I found box of assorted O-rings in bulk with the same outside diameter as my bolt. But my concern was how to make it hold on the bolt. I eliminated the ' Crazy Glue' option , then I thought of the Loctite ADHESIVE (blue) in gel - this adhesive there is 10x stronger than Crazy Glue. But I was anxious that the O-ring would stay on during shooting.
RESULTS:
I shot approximately 700 times in semi-auto and the full-auto at home in " dry-fire" and the O-ring held out. then with remainders of balls (Triumph and Nightmare) not very fresh and I made tests in semi-auto and the full-auto with 15bps at 300 and 310 fps to prove the concept. No breakage. I shoot at least a case from Blaze, Triumph and Nightmare, half of time in the full-auto, and no breakage.
Thus conclusion: I Will pass this to a well-known company which manufactures popular upgrades maybe they will make a prototype… "
