Fix my gun Dlask issues, tell me yours.

I'm building out a couple Tuf-22's and the first was plagued by fitment issues between upper and lower. Now after significant work I've gotten a better match but some of my H3CR mags will not seat fully. Anyone have experience with this? Any other issues anyone has come across ?

My new Dlask build is stovepiping, and the HC3R doesn’t feed all that well compared to the factory 10-round rotary mag.

I did find that CCI Blazers seem to run okay in the mags. I’m still troubleshooting to see how I can make my Dlask build more reliable too. I swapped out my recoil spring for a lighter weight one last weekend, but I have not had a chance to test it yet.

I’m also thinking of shimming my mags to see if that will improve feed reliability. Slight movement does seem to impact feed reliability, and I'm using an SBI Superlight chassis, which has no magwell support.

A few of my HC3R stripper clips were also sticking, I think due to molding. I took a sharp flathead screwdriver and ran it up and down along the stripper clip channel (perpendicularly, i.e., | - | where the - is the screwdriver bit) to widen the channel slightly so the rounds feed better. But overall, I find the HC3R mags too fussy.

UPDATE: I took my rifle back to the range today and had a great session. The gun and magazines are now shooting great.

  • Cleaned rifle, removed dry lube and used regular gun oil
  • Changed recoil spring to a weaker one (my barrel is only 9" take that into consideration)
  • Properly stacked the HC3R magazines, this is the best method: https://www.reddit.com/r/canadaguns/comments/1469qr0/10_1022/
  • Installed a stronger magazine plunger spring.
  • Make sure the magazine is pushed all the way forward.
  • Changed ammo to Federal Automatch as per u/chatoyantlumber's recommendation, Blazers and CCI Mini-Mags also work very well. Aguila was constant jams.

I was able to shoot about 200+ rounds almost flawlessly.

I think the biggest improvement was the recoil spring. Using Federal Automatch also helped to feed more reliably as I noticed Agulia and Remington Golden Bullets still has some feed issues but Automatch did not. I no longer have stovepipes!

I also ordered some 12-24 UNC grub screws, which I installed in the mag well (where the V-block bolts go) to put pressure against the magazine. It seems to keep the mag from shifting!

Aguila Super Extra CPHP would not cycle well for me as well; not sure if it is the gun or mags. Remington Golden Bullet was hit or miss for me. I had the most luck with CCI Blazers 38gr. I picked up 1000rds of 40gr, which I will test this week.
I agree, the stripper clip concept is dumb and pointless.
It’s too bad Butler Creek or Ruger doesn’t make TUF22 magazines.
