[QUOTE="25WSM, post: 1880583, member: 38048"] Someone ask about Bordin bumps. It's where the bolt body has raised up sections so when the bolt is in battery there is no verticle play in the bolt body. This helps keep both lugs touching when cocked. If you have any slop in the bolt in the rear of the receiver when cocked the seat engagement will lift the rear of the bolt up to the top of receiver. This will put more pressure on the lower lug and lift the top lug off the abutment. When the bolt is lifted and cycling the action the bumps are in the raceway so you have clearence for smooth cycling. Hope this helps. Shep [/QUOTE]
