Its the omega x FSB, I want to remove the hand gaurd plate on the back of it. Dont I need to remove it before I take the barrel nut off?

Yes, the FSB will need to be removed before the barrel nut can be taken off. Are you having problems driving out the taper pins? Make sure you are trying to drive them out from the small end. It's best to use a front sight block such as the one Brownells sells.

Additionally, I heard that with the new hammer spring that comes with the upper receiver, the trigger pull increases to 10-11 lbs. Is this true? I

No. It's fine, very crisp and works out in time to an excellent trigger.

Actually yes it is. I have about 1000 rounds through mine after replacing with the orange spring. My trigger gauge still reads at 10.5 pounds.

Here is my S&W 5.45 upper on a DD lower. I installed a DD Omega X FSP 12.0 quad rail on it. Next up is finding a stock I like to put on it. Either a Emod, ACS, or CTR.

It has run 100% with half of my c product mags. The other half it has absolute fits with, such as not locking back and issues cambering rounds. I need to solve the issue with the weak mag springs.

Did you have a build-up of red/orange corrosive residue?

Did you have a build-up of red/orange corrosive residue?

Red from the BCG more than anything else,

figured they may have also been from the primer sealant but most was built up on bolt face and inter to firing pin channel

so i became pretty convinced after this test that lots of lube and she is good to go until i want to clean it.

some cp mags are still giving me fits
