It's about 23 ounces, fully loaded. A fully loaded .223 30 round PMAG is about 19 ounces, so it's just a little heavier but not enough that it bothers me shooting
I am very happy with it. The main reasons I went with the Pac-lite upper was weight, threaded, I like the fluting, and looks in general. As far as gaining performance, the quality of the Ruger upper is also excellent so not so much. But I didn't lose any either. I have noticed with the lighter weight I am quicker on target, so that"s another plus. Both uppers take whatever I feed it with no problems.
I've just always been used to spring loaded mags, so I tend to want to press and guide the round into the magazine. These you just drop and jiggle. I found watching from the back of the mag helped me. At first I was always getting a round just a little crooked or skipping a tooth then it seizes up and I'd have to waste time freeing it up. Watching it to make sure they are lined up before advancing it, I can load it in seconds, instead of fighting with it for a minute or two.
Mine has worked great for me. After the initial getting used to loading it right, I've had no problems at all with it. I think I'll get one with the 10/22 tower next.
Here is my latest project. I wanted a full sized, light-weight 22 with a threaded barrel for packing and plinking. I chose the Ruger MarkIII 22/45 with removable grip panels. I replaced the solid steel factory upper with a Tactical Solutions Pac-lite upper. It is amazing how little this set-up weighs. A standard MarkIII is 44 oz, the standard 22/45 is 34oz and the Ruger threaded 22/45 is 32oz. This set-up is 22oz. Fully loaded and with a Silencerco aluminum 22Sparrow suppressor attached it is only 28oz. ;D other add-ons included a Volquartsen MarkII trigger accurizing kit and a Pachmayr grip
I'm Rob and live in Billings. Both me and my daughter enjoy shooting. With the rising cost and availability of ammo in the recent years, I've gone from two 22s up to nine now. A Ruger 10/22 and a High Standard HD Military were my starters. I have since added, a AR conversion kit to swap around in my AR types. a dedicated 22 AR I built from parts. a GSG-5PK. a Walther P22. an old 3-screw Ruger Single-six. a Ruger Charger. and my latest is a Ruger 22/45RP that I just put a Pac-lite upper on. They all are mostly used for recreational shooting, that way we can go shoot all day and still be able to afford to buy some food for dinner. I'm glad I found this site. It looks like a great community of people with common interests.
