Century Arms C53P pistol in 5.56 less than 100 rounds fired. This is a clone of the HK 53 which is basically an MP5 chambered in .223/5.56. This gun I purchased brand new and after changing to the correct locking piece it runs perfect. As far as I can tell it was built mostly with a demilled HK 33 parts kit and has mostly german parts. Comes with magazine and original charging handle. I upgraded the locking piece and charging handle for reliable and easier use. Sorry no trades. I can meet face to face in the Austin/Central TX area. I will ask to see a Texas DL or LTC and buyer to fill out a bill of sale.
