Yes it will. The Geissele Super 42 Rifle Length Buffer Spring doesn’t have a reduced inner diameter like the Super 42 Carbine Buffer Spring does. Geissele recently released there own performance data using their Rifle Length Super 42 Buffer Spring with an A5 Buffer Tube, and A5 Length Buffer.

Yes it will. I have a PSA saber pistol that has the vltor A5H2 buffer system with the sprinco green spring. out of curiosity I removed the Geissle super 42 Rifle Length spring out of my 20" and there is NO problem. If anyone else is wondering you are good to go.
