The Magpul PRS Extended Butt Pad (part no. MAG350-BLK) replaces the standard rubber pad on a PRS or MOE stock with a thicker version that adds roughly half an inch of length of pull. Magpul Industries molds it from black rubber and builds it to bolt on with the stock’s existing hardware, so there’s no new mounting kit to buy. Shooters who find a PRS or MOE stock a touch short — especially running a plate carrier or heavy winter layers — use this pad to dial length of pull back to where it should be without replacing the whole stock. It’s made in the USA and covers a wide range of AR-platform stocks.
