Just get it - OpticsPlanet Exclusive Real Avid Master Grade Build Tool Combo

Ive built a few PSA build kits over the years and settled with short chinesium dedicated castle nut wrenches that barely got the job done. Tried replacing the back plate with a QD sling plate on an already assembled AR that had no loctite applied and even after drilling out the staking I couldn't get torque without those tiny wrenches breaking. Bought a better quality but same size and it didn't break but still couldn't get the torque.
Finally just dropped the money on these since they were on sale (still not cheap but on sale)
Dude. These are good quality just holding them. They have heft. The "axe" tool is long enough to get enough leverage. I probably spent close to this much on junk over the past 10 years if I'd have just got this to start I'd have saved so much dang frustration.
