No weirder than a Ruger Mini-14 (which is a scaled-down M14 rifle, usually with a wood stock), or M1 Carbine (wood stock even with a folding buttstock). Or a BAR Mark 2 (the semi-auto-only hunting version of the Browning Automatic Rifle, usually sold with a wood stock). Or SKS, for that matter (usually sold with a wood stock, unless some heathen has refitted it with a plastic stock). Or (my favorite semi-auto rifle) the SVT40. But most serious accuracy rifles these days (say, Remington 40x competition rifles) are using composite stocks, because wood stocks can swell or shrink with weather changes and change your point of impact. So even Grandpa's hunting rifle may get a 'plastic' stock put on it (or may have a plastic stock on it already if Grandpa hunted in crappy weather) The Contenders (particularly the YJ Contender) seem to be used in Aristeia, so bolt-action is probably too slow for hitting the next target. Note that Lunah's primary Aristeia skin is still using that Haqq Viral Rifle. Though I suppose you could get fancy with a biathlon-style straight-pull. A semi-auto like the AR is a straight-pull bolt action if/when the gas system fails. When the gas system works, it's using a little bit of gas that would be pushing the bullet downrange to push the bolt back. But in extreme accuracy events like biathlon or long-range shooting, a semi-auto starts moving before the bullet leaves the muzzle, and that reduces your accuracy.
