How's the fit of the gas tube in the new gas key? Any noticable "mushrooming" on the end of the tube? What leads you to believe that the gas block has shifted, have you loosen it or worked on the barrel?

Just another guess but how many rounds on the original BCG, could there just be additional friction on the new bolt where it meets the receiver? Do you run the bolt "wet?"

Not totally unexpected, so I try all combinations to rectify this.
HD2 + std.spring
Std buffer + Blue Springco
Std. Spring + Std. Buffer
The only thing left to try is putting back the Stock BCG which is only marginally lighter than the FA, but I did not have it with me to try.
So here it is, are the RR that precise in the gassing that it won't allow any modifications? I know that RR are not over gassed but this seems a little extreme to me. Second guess could be that something has happened to the gas block, shifted or something similar that has restricted the gas flow. Is anyone running RR with mods of these types?
Thanks in advance for any FB...

This is exactly what I was refering to when I said changing the timing. Each manufacturer is gonna port their systems differently. Miniscule variances are going to make each and every gun different from the next on the assembly line. If you gonna play with your timing bring all your toys. I haven't bought any lower or higher rate springs but I have carbine, h, h1,h3 and rra 9mm buffers. I usually try and use the weakest powered ammo (russian swag) and time it with that. I try and use the heaviest buffer that will cycle reliably. Onetrick is to just load one round in your mag. If your bolt doesn't lock back after firing, your gas system is short stroking. Time to move down to a lighter buffer.

If you time you system with higher power stuff like mil surplus m855 or m193, you will find that you can run heavier buffers. Problem is you'll short stroke the weaker ammo.

One peice of gear hat only costs around $60 and will get around all this gear swapping is an adjustible gas block. You can tune it on the fly and get the most out of your setup. I haven't made the plunge yet but for sure my next build will have a JP adjustable block and rifle length gas system (spr-ish type build).

Yes I am running wet, New FA BCG is stiff, original gas tube was a good fit in the YHM low profile gas block. There was nothing wrong with the timing, just softening the muzzle rise for faster follow ups. I am a little confused because this weapon is not wanting to take any thing other than original parts and or specs.

How about the other end that fits into the gas key...does it get a good seal?

Any time you change the spring rates or the reciprocating mass you are changing the timing. If you add weight or up spring rates you slow down the timing lengthening it and reducing percieved recoil. If you lighten mass or rates, it shortens recoil impulse also makes the bcg go out of battery at a faster speed, all of which increases percieved recoil. Its all about the timing.

As for your rifle, sounds like RRA gassed your gun just right, maybe u don't have to change anything.

Whats the differences and purposes between H buffer or Spikes T1, 2 and 3? Excuse me from asking. I think i got the H buffer in my DD. And if im not mistaken, the Spikes T3 meant for suppressed AR? Thx

Long story short.

For semi auto applications, its usually best to use the heaviest buffer that will cycle your ammo reliably.

You can tune it for each different type of ammo easily, because swapping out a buffer takes what, 10 seconds max?

Or you can tune it for the weakest ammo you have, and leave it. This way you know your gun will go through weak, mid and high power ammo.



The reason why people do it, is that you lengthen the recoil impulse (takes a longer time to cycle) when you increase the weight of the buffer, as it take longer to get that mass in motion to go out of battery and back into battery. While the actual timing part is not really necessary for SA applications (its much more import in FA guns) a longer recoil impulse makes the gun have a smoother feel to it, a kindler gentler recoil impulse. Its helps a little bit, but not nearly as much as a good muzzle brake.

Is this a midlength or carbine length gas?
