The Sig Spear LT exhibits noticeable barrel flex and point of impact (POI) shift under external force, with the first shot after flexing deviating significantly. However, the rifle tends to return to its original zero after 1-2 subsequent shots. Compared to the Geissele URGI, the Spear LT showed greater POI shift, though it remains practically accurate for combat distances if not abused.

Directly resting a rifle barrel on cover or support significantly degrades accuracy by disrupting barrel harmonics and causing flex. Demonstrations show a shift from consistent hits to multiple misses when the barrel, rather than the handguard, is used for support. Longer barrels are more susceptible to this effect due to increased leverage.
