I was interested in a Hakim, but I decided to get myself an FN 49. The Ljungmann sounds frigging scary!
Don't keep yourself from experiencing that great battle rifle!

If you do things by the book, you'll never get bitten.
First, put the safety on, insert the magazine then push forward on the carrier cover until you hear it latch on the carrier.
Pull the assembly to the rear gently. Now the action is open. Flick the safety off and tug rearward just a bit more on the carrier cover. This will release the latch, allowing the carrier to spring forward and chamber a round.
You can, sometimes, actuate the latch release WITH the safety still on by pulling the carrier cover/carrier/bolt assembly smartly to the rear until it smacks the safety block.
After firing a magazineful, the bolt wil be retained to the rear by the hold-open catch. Engage the safety
and push forward on the carrier cover to capture the bolt carrier. Once done, you may use stripper clips to fill the magazine without risking your fingertips.
Never, ever, put your fingers in the action without first putting the
safety on.
And if you prefer not to put your fingers in or around the action, just pull the mag and reload it separately from the firearm.
Have SAFE fun!
