This AUG parts kit contains all surplus parts required to build your Nylaug. It comes with a complete right-hand stock, bolt carrier group, trigger pack, and gas port.
This is a complete key parts kit. It contains the foregrip cap, foregrip spring and gas block piston.
The barrel stub will be cut and pressed out of the gas block. You don’t need to purchase a separate gas block pressing service – we do it for you!

Picked up the NylAUG SME Complete Kit and couldn’t be happier. The surplus optics rail mount was in great shape and the mags locked in tight. Little details like the included spare recoil spring made it feel complete. Built it, zeroed it, and it’s a tack driver at 100 yards.

This kit made the NylAUG build a breeze. Really liked how the handguard retaining clips and all the small hardware were included and in good shape. The trigger has a decent pull for a surplus pack. Put 200 rounds through it last weekend — zero malfunctions. Great value.

The complete SME Surplus Kit was exactly what I needed. All the bushings and heat-set inserts lined up perfectly with the nylon receiver. Really impressed with the condition of the gas piston and regulator. Shoots flat and accurate for a bullpup. Awesome project!

Just got my NylAUG SME Surplus Kit Complete in the mail. The surplus stock and bolt carrier were in really good shape for the age — minimal wear on the bolt face and the gas piston was clean. Everything bagged and labeled nicely. Paired it with my printed receiver and it dropped together with almost no fitting. Shoots great
