What are the pro/cons?

As I understand lightweight BCG will cycle faster, but have more recoil? Is it really that much faster that one would notice while shooting in semi-auto?
 
Skeletonized will have LESS felt recoil than a full auto BCG provided it is tuned correctly with an adjustable gas block as there is less mass being moved around
 
The impression I get of a 'full auto' has more material on the bottom near the rear of the BCG.
This changes the timing/how it interacts with the hammer for full auto firing while ensuring the bolt is closed before the hammer drops. (or that extra material contacts a special component allowing the hammer to drop in a full auto trigger set up?)

If your looking for more buffer weight maybe this would help with that. (expensive way to do it?)
Otherwise I think its just extra weight, and possibly marketing. Who wouldn't want a full auto part (Sounds cool, sounds stronger) in their AR.
 
If you go Light Weight, make sure you have adjustable GB, otherwise the BCG will be running wild back and forth , early unlocking of the bolt and bounce , your buffer system will also play a big part. The bcg / and buffer system are a reciprocating Mass, the heavier the more felt recoil. With adjustable GB you can tune your gas vs the mass to get the optimum sight recovery., reliability was never an issue on all my rifle as long you never set your gas at minimum setting just enough to cycle the action, eventually you will learn how to tune/ set up your gas with corresponding buffer system ,
 
Not sure if skeletonized is an actual definition for BCG, but I know that my JP lightweight BCG has significantly less material on it than a FA BCG.

If I was doing anything except competition, I'd prefer a standard or FA BCG as they are likely far more durable.

I haven’t used it or own one, there are now Titanium Carrier on the market, its light and full profile, never dared to own one, my wallet can’t handle it, but sure interesting
 
Think of it like a race tuned car versus a Honda Civic. Do you want to have to feed your gun a specific brand of ammo or have highly tuned reloads or do you want to just feed it whatever ammo you can find? High test race fuel vs regular gas at the pump sort of deal. Personally, the 223 round recoils minimally to begin with and is easily controlled with proper training so in my opinion going super tuned with lightweight this and that only interjects the likelihood for reliability issues. My rifles will run everything from the highest quality match ammo to the dirtiest of the dirty, and they do it accurately and reliably, recoil and speed well, that’s on me as a shooter.

I have a skeletonized titanium BCG on the way from RCA, supposedly almost as light as the JP aluminum but pretty much the longevity of steel - no downsides - looking forward to trying it.

I saw a JP LMOS BCG at the range last week, it was a thing of beauty and would probably have been the direction I would have went were it not for the RCA.

The LMOS with an adjustable gas block really is something for competition. Zero recoil with the right comp and almost no impulse. 223 is light as it is, but with this setup, doubles are virtually side by side.

Mine has been totally reliable...never had an issue but I only shoot factory ammo. I'm just not convinced it won't break one day....that's why the answer somewhat depends on the OPs intended use.

Here's some video while I was in the US

Yes, I went with the RCA for the same reason - competition. I will be running reloads so I guess its on me to make them as consistent as possible and ensure that Ive tuned a little on the safe side for reliability purposes.

I'm sure it will be a massive step forward from my current setup (X95) - its overpassed for sure and it does have a big heavy bolt slamming back and forward (relatively speaking) but its been 100% reliable.

I know aluminum BCGs (JP`s lightest offering) are wear parts but to the best of my knowledge the titanium and others are not and should last a long time. The JP LMOS I saw last week looked like a beefy unit. Time will tell I suppose.....

Cant see the video - it says it is private.
 
ok, so what I understood that if I have adjustable gas block (which I do), it's always better to get lightweight BCG.

If the end goal is a flat shooting rifle with minimal recoil then a lightweight BCG and a correctly tuned gas system (via an adjustable gas block) will help achieve that
 
I have lightweight BCGs on all mine with stock non adjustable gas blocks and T2 buffers and they all run 100% reliably. They're all carbine length gas SBRs.

Better?, maybe since you can optimize and take advantage of the gas tuning of your action, if you prefer not to go with LW BCG you can still benefit from the adjustable GB, most of the factory rifles are over gassed because the manufacturers wants to make sure that your rifle will run, but sometimes over is not better, also consider the longevity of your rifle, brass extraction, .. before the spring and buffers are the parts involved in masking the Over Gassed issue, with Adjustable GB you have another option.
