I know this has been beat to death on a carbine buffer. I bought a CTR Mil-spec stock, tube, carbine spring and buffer. After waiting a couple of months for the MK68 Recon upper to show up. I just noticed I have an H-buffer (carbine) with standard spring. I am in the process in breaking in the barrell, But the Recon spits the SSA TNT 90 right at 3:30.
Any or what issues would I face by keeping the H buffer. What if I purchase SSS spring for it as well? I plan to reload my own to H's load data: 90 TNT, 85 TSX, 100 nosler Accubonds if become available.
