Fitted my AB Biller speargun easily. The semi-closed design improves accuracy and sight line. I followed the hot water soaking step and assembly went smoothly. No issues so far.

Good replacement part that matches the original. The nylon is durable and fits well. Just make sure to soak the parts before putting it together to avoid plastic warping.

Perfect fit for my older wooden speargun. The muzzle feels solid and the accuracy improved noticeably. Assembly was simple after soaking the parts in hot water.
