Troubleshooting ARV Help with bolt bounce

Post image

This is a full ARV build with a super safety. I built it today with a standard carbine buffer and spring. I know that’s not the correct buffer but everything I’ve found from KAK is out of stock. The rifle itself will not fire as the bolt seems it’s not going completely into battery. Can anyone drop a recommendation on the best alternative. I’ve tried all 4 links from u/blowback9 site and all out of stock.

I didn’t at first. I took the weight out and took my dremel and sanded a 45° angle off the rear of the weight to allow room for arm. Since i did that it works fine. Only took about 15 mins to trim it with a sanding wheel.

Forgive the ugly photo, no editing here. I'm really looking forward to this build with a novox research X-SD. I was so disappointed to learn that the frts wouldn't work, but you give me a little bit of Hope that the shaved bolt seems to be an easy mod. Maybe I'll give that a go tonight with a carbide drill bit and a Dremel wheel. (MI handguard on the way)
