who makes them and which one is the best , temper got to me after I missed a crow, for sure my fault but gun took the brunt , those 3 1/2 tripple bb,s will do wonders for your shooting ,also its a mark v , any help would be greatly appreciated

A few years ago HS Precision was making the synthetics for the Mark V's but now they're getting them from Bell and Carlson, it's the same stock basically with someone elses name on it. Those are probably your best bets for an OEM replacement.

thanks for the info
