I have 2 new Begera rifles. I listen to responses on African Hunter website, called 3 gun shops, watched YouTube videos and call Begera. After compiling and comparing advise I set out on the journey to loosen the muzzle brakes and can now screw them on and off barrel.
I wrapped my barrel with a rag and placed barrel in my shop vice. Grip was snug enough for barrel/stock would not twist and turn.
I then began to heat the muzzle brakes with my electric heat gun. It did not produce enough heat to loosen the muzzle brake.
I followed up with a propane torch. I did not allow the flame to touch the barrel or brake. I applied heat all around the muzzle brake. I placed a rod in the muzzle brake hole and suddenly the grip began to loosen. I screwed the brake completely off from the barrel. In a short time the barrel and brake cooled. I then use Hoppe #9 to clean thread section on barrel and the thread section inside the brake.
I oiled the barrel threads and screwed the muzzle brake back on to the gun and hand tightened it with the metal rod.
I will now be able to clean the barrel more easily and remove the break to give it a better cleaning.
Local gun shops were wanting charge me $130-150 to perform this job. Ridiculous!!
