Why upgrade if it’s so awesome to start with? Simple… because you can. And honestly there are some upgrades that add to the comfort of the rifle. Not all upgrades have to be very expensive either.
TactiCrayola – This is nothing more than some crayons and some time to enhance the stamped lettering and logos on the weapon with a crayon for a more refined, “professional”, true AR look. Check out the YouTube Videos on this project.

Hogue Overmolded Grip – This $15 upgrade is by far one of, if not the best upgrade for your 15-22. I went from the standard AR-15 grip, which IMO is crap. For my hands it was too “short”. I added this grip and the rifle instantly felt like and extension of my hand. Pure comfort. Available from MidwayUSA.com.
Rail Covers – The 15-22, being all polymer, still has rails that can be a bit rough on the hands. Invest in some Tapco rail covers for your rifle. Do not spend money on the more expensive packages. The Tapco covers are excellent. You’ll receive 5, 6.5″ covers for $13, if your order from MidwayUSA.com.
Foregrip – Adding an angled or vertical forgrip (your preference) can enhance the stability of your weapon as you hold it.
Optics – The sky’s the limit in this area. However I personally cannot justify a $500 optic on a $400 firearm. But that’s not to say that it’s not wicked cool to do so. I’ve read that due to the lack of recoil on a .22LR, that optics designed for airsoft or paintball guns will work well. I personally have installed a BSA scope on mine and I like it. Red Dots are all the rage on this rifle according to the internet.
