These things are awesome for the money. I picked up a couple of them in .308 and gave them a good cleaning, used some of that battle born grease to lube them back up and went off to zero them in after laser bore sighting. Spent about 20 rounds of el-cheapo 150gr getting them close and then switched to the 168gr that the kids will be hunting with and the groups got nice and tight at 100 yards. Tuned the gas system to get flawless cycling without being over-gassed. What a great hunting rifle for kids! Nice and light weight and mild recoil. I am very impressed.
