We present the dijet invariant-mass distribution in the region between 60 and 500 GeV, measured in 1.8-TeV $\overline{p}p$ collisions in the Collider Detector at Fermilab. Jets are restricted to the pseudorapidity interval $\left|\eta \right|<\mathrm{}0.7\mathrm{}$. Data are compared with QCD calculations; axigluons are excluded with 95% confidence in the region $120<\mathrm{}{M}_A<210\mathrm{}$ GeV for axigluon width ${\Gamma }_A=\frac{N{\alpha }_s{M}_A}{6}$, with $N=5\mathrm{}$.
