The SR-22 is a better set up.
To get Klrklr's set up, that handguard alone costs another 350$.
So i bought it... i am happy to say the least, borrowed an eotech holo sight to test it out and it shot great, was using federal ammo, had a couple failures to eject shot 100 rounds maybe 3 in total, i was told by the store that the federal would have a couple failure to ejects because they dont have enough power, but with premium ammo it will function flawlessly.
