Bought a Pac-Lite receiver for my MKIII and...
I took it to the range today and I'm having some issues with it. I originally bought a regular Ruger MkIII with the tapered barrel and have shot around 500 rounds through it with not one single FTF, FTE or failure to go bang. Great stock target .22 pistol! I installed a Tactical Solutions upper receiver to my frame and did the range thing today. I got about 10 misfires (out of a around 300 rounds or so) and a couple of FTE and I am kinda bummed now that my 100% reliable target pistol turned into this. I did get firing pin hits on the rim of the cartridges but no bang and they seemed kinda light. I'm specifically using CCI 40gr Subsonic and Federal 40gr HV copper plated and have never had an issue before with my P22 or stock Ruger MkIII. Why would my bolt and internals work 100% in the Ruger receiver but all of a sudden start doing this in the Pac-Lite? The problem seemed more pronounced with the Gemtech on it. When using the compensator it seems to act better. The comp makes it unusually loud for a .22 btw.
my setup
I am going to upgrade to the MkII Volquarsten accurizing kit with a MkII bushing soon, but what can I do in the meantime?
Is it a new Paclite?
Reason I ask is the breech will mushroom over time exposing more and more of the abrrel liner. I have already had to send one back and they replaced it. Now I am a few thousand into my replacement and it is getting ready to go back also. The first one had enough of the barrel liner exposed that I finally quit shooting it over safety concerns.
Here is the first one:
I am glad your not getting baffle strikes. I got baffle strikes with the first and the replacement PacLite. No other gun baffle strikes except the PacLites.

If I were to design that product I would have done 2 things very different.
1. Make the upper 7075 T6
2. Have the chamber end of the barrel sleeve be the full I.D. of the receiver so the bolt face has steel to impact against.

I would buy one of yours.
Even though they say they will replace it every time it happens it is just a pain in the but to send it off every 6 months for repair or replacement. Now it just sits in a drawer not being used.

Thanks for posting this OP. I was about to order one of these, and you guys saved me money and frustration it appears.
Looks like you guys can get a better product straight from Ruger now.

Question is what kind of aluminum do they make the upper out of?

You live and learn. A factory Ruger 22/45 with threaded barrel and rails is in my near future.

The design is totally different, so simply comparing alloys doesn't tell you much.

It tells me if they skimped out and went with a cheap alloy or not.

My point is that the Ruger's breach face is steel, and integral with the barrel, thus the TacSol problem is impossible due to the Ruger's design.
Plus Rugers customer service is so much better than TacSol. I would be using teflon tape to keep the TacSol barrel threads from getting used up before their time. I finally went to a threaded steel Ruger for a host.

Bought one today.

I have a PAC-LITE upper on my Mk.II and it works very well. I have more than 1K and have not noticed any effacement of the breech as illustrated in Dolomite's photos. In fact, I see no wear pattern to develop at all. My one complaint is that EVERY threaded part of the upper required locktite to stay in place plus the rear sight pin walked out during the first range session. I even had to buy a .5x28 to .5x28 adapter for the muzzle threads just to make my Sparrow snug. If I had to do it again, I would have just purchased a factory threaded MkIII as a complete gun for not much more than I have into the PAC-LITE (which is also considered a "gun" all on its own). Unfortunately, the factory threaded guns were not an option when I purchased my Sparrow.
