Can you throw it on the older model barrett m281's?
Must be the older dyslexic model of the M82a1.
This new bipod isn't released as of yet, but, it appears to attach via picatinny rail. So if you could mount a rail on the forward portion of the M82a1 then YES, I think it would work.
But, perhaps KASEY could give a definitive answer?
