We finally hit the range with our newly installed Bolton gas block and Wolverine flash hider.  Firing a approximately 250 rounds, we did not experience one malfunction with the new system.  We are really impressed.

The rifle handles significantly better with the Bolton and without the old gas block, front sight and muzzle brake.  Balance is perfect, and the rifle is quick to bring on target.  The front sight maintained its postion and the pinch screws held the block firmly in place.

These are the parts we stripped off the barrel and replaced with the Bolton gas block.  The original gas block (top left), front sight (top right) and the 74 style brake (bottom)

We will keep you posted on how our block holds up.  Our impression continues to be exceptionally positive. In fact, we would suggest this is one of the best AK upgrades we have encountered to date.

Next, we plan on cutting and crowning the barrel and silver soldering a extended Wolverine flash hider in place.
