Hi Jason and welcome. I have through both my GeForce Bullpup and VR-80 AR-12. The bolt springs are stiff which is why break in of 1300 fps or higher is recommended. The trick to mitigate this break in period is to store your AR-12 or Bullpup with the bolt locked back which seasons the spring to allow lower power loads to cycle. Cheers and stay safe!
Stiff bolt springs so I would break it in @ 1300 fps or higher. It's said to store your AR-12 or Bullpup with the bolt locked back which enables the spring to allow lower power loads to cycle.
Good evening to you!! My Gforce gfy1 and gf25 would not shoot anything under 1300fps until they were broken in. I took James G advice and store them both locked back and cycle them 10-15 times weekly. Hope this helps. Have a good rest of your 4th weekend. 🇺🇸🇺🇸'merica' 🇺🇸🇺🇸
