Tried my new Titan 10" upper on my m16 and it ran great, 800 rounds and no issue except that my mag kept dropping out.
It doesn't drop mags with a M4 15.5" barrel.
Fit and finnish was much better than I expected. Balance was great! No feeding issues at all!
Thinking the shorter barrel hits back harder. I put a toothpick in the side of the mag release button and they did not drop.
The short barrels must shake things up a bit more shaking up the loose mag release button.
But I love the Titan upper! the fit and finish was much better than what I expected.
I will try a new button spring. I was wondering if anyone had a mag drop issue with a shorter upper.

Thx

The Magwell and catch are all part of the lower so I would focus on that before the upper. Try a new mag well spring, catch and Button first, maybe different mags. Swap bolt carrier groups as the bottom of the BCG make contact with the rounds and pushing down on the mag spring, I doubt this is the issue but worth a try.

I don't see how the barrel length would have anything to do with this. An SBR shouldn't have more recoil, it's the same round being fired, the difference is likely you're not used to the grip/balance and it feels harder to control. Practice makes perfect.

I think the op is referring to the really hard recoil. Iirc the Titans gas block is a bit out of spec and is over gassed .

OP have you tried a h3 buffer?

Can the mag catch be tightened an extra turn or two?  This might be all you need.

X2, I would check this first.  Is the catch threaded flush into the mag release button?

I swapped out the mag catch parts with new FN AR15 parts.   WOW! The FN spring was about 1/5th longer.
I will give it a try it and see if it works.  Then thinking I am ok?
I just dont want to risk damaging the M16 lower wit a over gassing problem.  It has a H3 buffer and timing is great, no miss-feeds at all.
It does not have a mag drop problem with the 14.5 upper.  But I know a piston upper is different.
Think the lower could get damaged????

I seriously doubt you will damage anything, just run it and watch things closely for a while to make sure things are running right.

I never heard anyone blame a gas block for being over gassed. Most if not all gas blocks have a hole substantially larger than the gas port. The over/under gas is determined by the size of the gas port in the barrel. A gas block can't increase the amount of gas coming out of the gas port in the barrel. You can get gas blocks that are adjustable and restrict the flow of the gas coming out of the gas port, but running wide opened it's all the same.

It's a piston gun.  The clone gas block is not vented the real ones are vented to prevent over gassing!

Do you have a Titan upper?

The Titan uses different size Pistons to control gas.

Op is it recoiling really hard even with the h3 buffer?

yes, its a Titan.   I think it feels fine, timing is on great, no failure to eject or light strikes.  I like it the way it is but the mag kept falling out.  it stayed in if you hold it by the mag to keep it in.
Works real well with the h3 buffer.
I am just afraid that it could damage the m16 lower $$$$$$$.
but I dont feel the recoil that bad for me.
I could try the new mag catch spring.

Great , I had good luck with a hk 416 spring and buffer really softened the recoil
