Took my PWS Summit out to the range last weekend to sight in my new Mueller APT. The rifle probably has around 300rds through it before this trip and I keep it clean. I noticed that I had a lot of light strikes which was a first for this rifle. I'm estimating 3-4 light strikes per 10rd mag. I originally thought it may be an ammo issue, however it happened with 6 different brands of ammo. Just wanted to see if anyone has had any issues with theirs? This is a factory built rifle.
