SigSauer MCX Spear LT lower (QR spring) AEG/HPA

I've created this model as I'm hyped about MCX Spear platform and since there's no decent model to buy from the store (except GBB ones!) here you go!

In order to assemble it please visit my upper project as well (https://makerworld.com/en/models/2827200-sigsauer-mcx-spear-lt-upper-aeg-hpa).

I strongly advise to use SLA printer with resin similar to Anycubic Tough resin ultra but if you use sturdy materials like PETG-CF or ASA-CF it will work fine (I've tested it on regular PET-G and was bit to brittle).

I've added original SigSauer logo and markings (with small tweak since I produced it in Poland, Masovian voivodeship XD ) along with caliber for 6mm BB's.

Project got two main characteristics:

1. back hole for the quick replacement spring system
2. place to fit brackets from upper project so it'll not rely only on Sig's bolt lock mechanism (filament nor resin isn't sturdy enough to keep it together).

In order to assemble it you'll need 2 6mm pins (recommend metal ones that can be purchased in any ASG store) and mag release (also metal one for standard Specna will fit). 

Print recommendation:

At least 5 walls

decent support structure (can be used with PLA as a support interface or any other material that don't tack to main one)

At least 50% infill - Gyroid to evenly lay the impact forces

In case of any problems please reach me before raiting the project. I'll happly explain and help with problems although reply time might be longer due to my work schedule.
