If you add a suppressor or booster muzzle device it will make the gun gassed more and can cause reliability issues.

ok i measured .081" and my current buffer is all stock. Stock carbine spring and weight which i believe is 3oz. I did not touch any of that. Also i would want to shoot off the shelf ammo. I don't think i am smart enough to load my own yet! lol

Unless there is some lightweight carrier or something wrong, a H3 should work unless you shoot steel cased or PMC.

The deputy's Sergent came to the scene and yelled at the deputy to get him out of cuffs stating that the instructors creds out weight the deputies! lol
Who was this "Instructor"? Where did this happen?

Nope the carrier is a spikes nickel boron and is not lightweight.

Ok so run a H3 and make sure it cycles and licks back reliably. So maybe run like 20, 1 round mags through and I should be good to go. If I have a problem drop to an h2.
Do I mess with the spring and just switch the buffer and before I go and pick a brand (learned my lesson from my barrel selection) what buffer do you recommend?

Avoid spikes buffers.

Any other American made buffer that is marked H3 is ok.

If the spring is suspect, and want standard springs Colt is the way to go. They are called action springs by colts nomenclature. If you want an improved life spring a Sprinco spring or Tubb spring will last the life of the weapon. You have to be sure you have a smooth buffer tube bore in order to use a Tubb Flatwire spring.

You may run into issues with NiB and the Criterion barrel as well as gas key issues. Those require gauges to check though.

Ok understood. My buffer tube is a UTG. So will the colt spring work on UTG? My tube and spring are brand new.
Right now this setup is all with the Faxon barrel. The criterion barrel will not be here till next week. And that's where I will start build 3. But the bolt for that build is a bcm nitrate.

The Colt will work.

Check for bolt travel with that buffer tube:

With a $300 budget, you can do much better than Faxon.

Here's a Criterion 20" HBAR barrel for $300. This is a match-grade, 410R stainless barrel with a hand-lapped bore.
https://www.fulton-armory.com/barrel...ainmuzzle.aspx

If you prefer a different length or if you like chrome lined vs. stainless, they offer those as well for similar prices. If you shop around a bit, I believe you can find Criterion barrels for as little as $250 with coupon codes at places like Brownells.

Also consider White Oak Armament barrels. They offer match-grade 223/556 barrels starting in the low $200 range.

ok. yes i went cheap on the tube cause i figured i was going to change the the spring and buffer also i have a magpul stock on it as well. I also have a bcm 6 position buffer tube as well. Maybe i will just switch them out since you might be indicating that the UTG might not be the best. lol
