PAC-LITE feeding issues
So I picked up a used pac-lite upper for my 22/45 and shot it for the first time today. It had a lot of failures to feed. All were rounds going nose up into the top edge of the chamber. Never had that many issues with the original upper, so I pulled it apart for comparison when I got home. For starters, the pac-lite fits much looser to the frame, but once it's all together there's not much wiggle. The bottoms of the feed ramps are different, but looking at it with a mag inserted the bottom of the feed ramp never comes into play.
The feed ramp to chamber opening however is a different story. The factory is fairly smooth with just the slightest hint of a lip. The pac-lite on the other hand has a very pronounced lip at the top of the feed ramp. Pics below for reference. Just sticking the nose of a bullet in through the ejection port and sliding the rip up the ramp I can tell a difference. The factory one has nearly no resistance between the ramp and into the chamber. The pac-lite has enough of a lip to stop the bullet tip.
Thinking about taking the dremmel and just hitting that lip with a stone bit to smooth it out a bit like an M4 receiver extension. Not taking much off, just getting rid of the sharp edge. Thoughts?

Re: PAC-LITE feeding issues
That does look odd... My new MKIV has a lip like that and same feed issues also. Been thinking about doing the same thing you said. My Paclite was insanely reliable. I put a little over 3000rds (95% were suppressed also) through it once without touching it before it started having ejection issues...haha

Random assortment. Some lead, some copper jacket, none were immune.Dave1965 wrote:ammo used?

Re: PAC-LITE feeding issues
I'll second this option! I've owned a few of his old 22/45's. All he messed with were great!Fudge wrote:Let me have it for a week or two. Ill work it over.
Seriously though- niceguys paclite was mine. Thats what I did. Thats why it worked so well.
My 22/45 runs like a sewing machine. Factory upper but its a mirror on any surface that touchs
