Ratings & Reviews
Heavy buffer & spring helps, but not 100%.

I bought this & the extra heavy sprinco Orange buffer spring because the .308 exhibited traits of being over-gassed, the most obvious a 2:00 o'clock ejection pattern. I was hoping this $70 worth of parts would put the empty brass at 4:00 o'clock but no. I'm at 3:00 o'clock consistently. So I may yet spend more money on a new gas block too. PA is fast to fulfill orders and ship out. I got the parts before the charge officially cleared my bank account. This is a well manufactured piece of kit. Would buy again for a different build
