SL-9 Complete Build Kit

An all in one kit to complete your SL-9 build! This kit contains everything found in the SL-9 Combo kit, plus a complete upper chambered in 9 x 19. This kit contains everything you need to complete your SL-9. All you need to do is print the lower!

The uppers are assembled to provide a logical choice for the SL-9 lower. The following parts are used:

• 11″ 9 mm barrel with 1/2 x 28 threads from Ballistic Advantage. This is the same length as a 10.5″ AR-15 barrel.
• 16 Ounce 9 mm bolt from KAK. Glock mag compatible.
• Type 42 flash suppressor from KAK.
• 9″ M-LOK handguard from KAK.
• Extended Warhammer charging handle from Breek.
• Mil-spec AR-15 upper receiver with standard dust cover and forward assist plug.

These uppers are assembled and tested in house. Due to the live fire testing the uppers may have some slight signs of wear or fouling.

The complete upper weighs 3.5 Pounds.

Note: the upper receivers rail does not feature the scallop cuts at the edges of the slots. The handguard does. While this inconsistency is a very minor point, it is something I found irritating, and something you should be aware of. This will be resolved on the next batch of these I assemble. – Tim
