The guns all come with equipped with their so called Enter & Convert™ quick spring change system, which allows a spring change by twisting the spring guide with a screwdriver by 45 degrees to release an change the springs. All weapons are delivered with a M120 as standard and a M90 spring for CQB. Other features include anodised receiver with laser engraved markings and functional bolt catch.
Most of these features are reserved for higher priced weapons, and this is where Specna Arms very low pricing which comes in at around £150 or 180 Euros gives players on a budget still the option to have the features available at only the mid to high end guns.
The SA-A01 displayed below is packed with a lot of extras such as a custom flash hider, a silver outer barrel, rail system with 10mm QD sling mounts, buffer tube sling mount, extended crane stock, quality 8mm bearings gearbox with hex screws.
All weapons are finished with the pulverization method after the surfaces being sandblasted, which ensures a hard wearing finish.
Overall you cant really ask for more from a gun that costs so little.
