Suppressed 11.5-inch PSA Pistol with Polonium-K

A budget-minded first build: an 11.5-inch PSA upper on a PSA Guardsman pistol lower, black with FDE furniture and an SBA5 brace. It runs an Otter Creek Labs Polonium K on a Rearden Atlas mount and SPB brake, with a Superlative adjustable gas block, BKF H2 buffer and Sprinco spring to suit it. A Holosun ARO, Magpul flip-up sights and a Breek Sledgehammer charging handle round it out.
