I used Blazer 124 exclusively and the gun ran perfected. New buffer really makes the gun reliable. Recoil is smooth. Ill be making one more change this week and that is adding some more mass to the buffer (5oz). Once i make that change, ill test it again

I switched the buffer system from the armspec SRS to the Kynshot hydraulic buffer and much prefer the kynshot. The recoil was softer and i didnt have to worry about ejection and cycling. The gun shot beautifully and was already sighted in perfectly from the previous range visit. This test was more for reliability and i put 300+ rounds through her without any issues what so ever. Did some rapid firing and the gun ran perfectly.

The gun ran flawlessly until I encountered a bad round. I shot 198 round with no issues, I used Repackaged ammo which was sold to me by x-ring as "good ammo" when in reality it was quite dirty. 165 rounds were standard repackaged Blazer Brass/Spear 124 gr. In between magazines, I also tried some defence Ammo (Sellier and Bellot JHP) and they ran great as I expected. The failure was on an additional round after some shots where the round casing split in 2 and became stuck in the barrel. I discuvered this by eating a face full of blowback and some bits to the cheek, I managed to clear the barrel of the partial casing after I got home. Going to try again tonight with some more Blazer Brass. I have some factory stuff. The lesson was, Never EVER use repackaged ammo, no matter what anyone says about it.
