Preferably the SB Tactical SOB one, though I'm open to other options... PSA has been out of stock on their $159 kit for a month or two and my 10.5" upper is going to be here soon. Wouldn't mind a kit that came with just the buffer tube, spring, and weight if the price was right... lets me just snag an EPT trigger and K2 grip (though I'd also be fine with standard MOE). Some help guys? Or was PSA really the only one offering such a deal?

I did a check, and can't find any other kits,, I had to order my parts from several places..

On my Mk18, I run a Spikes T2.

Eh sod it - went with the KAK Shockwave kit from DSG... $125 and came with an MOE grip and their LPK. They also had the MOE SL Carbine Handguard I was wanting on sale for $21.60. $5 shipping. Shouldn't be too terrible for a KISS build.

That's an H1 buffer, right? Does it really make much difference? Like how much does it reduce felt recoil and is it supposed to reduce wear/tear on the moving components?

Only other AR I have is a mid-length 16" FN CHF pencil barrel. Figured a carbine buffer was fine with such a non-aggressive gas system. Could be different with a carbine 10.5" though?
