Well all my parts finally arrived from USA - in drips and drabs as every order must be below USD100.

Tonight I removed my plastic hand grip using hand grip removal tool.

I had a hard time removing my muzzle brake (being red threadlocked - but a bit of elbow grease got it sorted).

Removing the clamp on gas block was easy - but removing the roll pin was harder.

The Barrel Nut was TIGHT - removed easily enough using my M16/AR15 armourers tool.

The freefloat came with the correct barrel nut so all I needed was the 0.750" low profile gas block.

The M16/AR15 armourers tool did not fit the new barrel nut to I improvised - got it on tight (1 hole past hand tight) with the gas tube running smoothly through it.

Reinstall new gas block - insert roll pin, install muzzle brake - all done.

Our rifle range is closed for renovations until end of February, so will have to post a range report after it is open to see accuracy is improved. I'm hoping .5" groups now that pressure variations on the barrel will be negated.

sharp shooting...

Keep us posted! You are making me sick mate!
