No PSG1 clones in stock currently. Check with us for pricing on complete builds including parts sourcing and receiver options. We will help you piece a gun together that suits your needs and budget! Some parts are very hard to come by and or unavailable all together. Most of our clones are built as accurized HK91s with as many PSG1 upgrades as possible/desired.

Price comes down to how much you want to spend verses how close to the original you want the gun to be. Give us a call to discuss your project and we will do our best to point you in the right direction. We can usually give you a good idea of what to expect price wise.
