Custom Springfield Armory M1A Bush Rifle I say custom because that is not the stock they normally come with. Note that there is the notch for the selector switch. The rifle is semi-auto but some owners like the look of the fake selector for that full-auto authenticity aesthetic. The Bush rifle had an 18” barrel and was meant to be a more compact M1A suitable for dense wooded/bush areas, hence the name. No longer in production if I remember correctly since Springfield Armory has the SOCOM 16 and SOCOM II.
