I am looking to fund another project so I have a PSA M4 up for sale. It is a rough M4 clone. Has the PSA M4 US Government lower, 14.5 pinned and welded barrel. 1 in 7. Bayonets do fit this rifle. Sig Romeo 7 with Picatinny Arsenal back up in rear. This was built as a trainer to duplicate an issue M4. Before someone points out that it is not exactly a true copy of the M4 I agree. It was built to duplicate for qual practice. Never had a malfunction. Low round count. as sits asking $850. Consider separating optic and rifle for right price. 337-230-1857
