I have a parts bin frankenbuild 6.5 Grendel.  I’ve been slowly upgrading parts.  I recently put a new scope on it and got a Geissele charging handle from the kids for Christmas.  

I’m thinking about swapping the buffer tube, buffer, spring, stock, and safety in a couple months.  

Is the Geissele buffer tube and spring kit that much of an improvement over cheapo no name parts?  

Should I go with and H1 or H2 for my suppressed 16 inch carbine gassed Grendel?

Thanks for the input.

No, if the no-name parts are made properly there will be zero difference. Make sure you buy a milspec, not a "commercial-sized" buffer tube. But this isn't a place I would get spendy.

The Geissele buffer tube is a high quality mil spec tube, solid all around.  The Super 42 Spring and buffer system is a big improvement over standard spring and buffer sets ups.  It smooths out the recoil impulse, gets rid of the twang, and expands the service life of the spring far greater than mil spec.

I don't have any input on the Grendel setup for the S42 weight that may best suit your needs unfortunately.  Primarily used for 5.56.

The Geissele spring kit is nice and a good upgrade.  Is it needed?  Probably not, but it is clearly nicer and lasts longer than a milspec spring and buffer.

Thank you for the replies.  This is my go to rifle that lives on my side by side.  I hunt with it, but also need it to be able to withstand moderate abuse rattling around all day in a rack.  

I’ve talked myself out of dumping the Grendel for a Ruger SFAR because I’m sitting in a decent stack of ammo for it.  I’ve taken about 6 deer with it so far.  Unfortunately struck out this year porch hunting.  

Im leaning towards a new Geissele buffer tube and spring kit. Magpul SL stock and SL grip.   My girls hunt with me and I want this thing to be as user friendly as possible for them.
