After the successful basic functioning test, I've bolted-on a few "upgrades"
. Nice thing about a .22 that's used for recreation is I don't have be quite so serious about adding high-grade accessories. I can do something just for fun.
Tru-Glo selectable red/green dot sight (circle-dot reticle) in a cheesy quick-release mount, basic black ladder-type rail covers, a Brownell's flash suppressor adapter for plain-barrel AR-style rifles with an old A1 FS on it, and an ambi Ergo grip. Big step up in feel and (hopefully) shootability.
