Tippmann A-5E with 249 Saw kit.. 16 inch barrel, HP QEV kit, was equalizer board and PMI 88/4500 Hp tank w/remote line.
I believe pretty much any medium to big bore barrel.
Tough for opponent to see
color could be brighter
What a solid find. They come packaged in a solid manner. I found no broken balls in either 1000 rd packages I purchased. Balls appear to have a nice tough coat on them which is good for not breaking in your gun or hopper. I fired off about 350 rds as my Saw has a 350 rd hopper. Shot most of it on full auto on my e grip and I didn't have 1 broken ball I could notice. No breaks in the gun or barrel and nearly every ball seemed to break on impact. Target was a piece of plywood about 40 yards away. Conditions were an Ohio January day (cold about 30 degrees) overcast. The fill could have been bigger and thicker in my opinion. It was decent size yellow but I have seen much bigger. Upon completion of test my barrel was hardly messy(which I liked). One great thing I like is these balls are camo tactical color so your target cannot get a bead on where the fire is coming from great for woods ball.
Nothing is perfect.. but for the price these are very good balls. Excellent for Milsim/scenario woods ball players.. not so much for speed ball kids. Can't beat the value of these
