🛠 SKS Trigger Group ‘Front Ear’ Modification

[True North Arms Corp]

Howdy!

We made a recent video talking about a small — but important — tweak you might need to make when running an SKS with a mag well adapter: trimming the “front ears” on your trigger group.

Two Ways to Fix It​

1. Trim the Ears
   • Use a bench grinder, file, or similar tool.
   • Take them down so they sit flush with the surface behind them.
   • Quick, easy, and effective.
2. Widen the Channel
   • Instead of cutting them off, you can machine or file a wider groove between them.
   • This makes room for the magazine’s rear rib without changing the overall profile much.

• Mark Before You Cut​

  The easiest way to know how much to remove?
  • Install your trigger group in the receiver.
  • See how far the ears protrude past the crossbar.

The Benefit​

Once trimmed or widened, your mag can seat cleanly and engage the bolt catch without obstruction. You’ll also be able to remove the mag without pulling the trigger group — and still use the OEM duckbill if you want.

It’s a small mod, but it makes your SKS run smoother with a mag well adapter.

Does the mag well adapter have any sort of warranty? I haven’t had much luck with 3d printed items surviving pressure and recoil even over short periods of time.
