Airsoft Magpul ASAP adapter spacer for Lancer Tactical AR15

thingiverse

I am going to adapt an ASAP sling mount to my Lancer Tactical AR15/M4 model LT-03T-G2. The buttstock collar tube lock and its mounting point on the Lancer unit have a smaller inside diameter than the actual firearm. This mismatch makes it difficult for the ASAP sling replacement part because its inside diameter is a few mm bigger. To overcome this discrepancy, I designed a spacer that matches the outside diameter and design of the Lancer upper and the inside diameter of the ASAP sling mount. The spacer fits tightly but should fit with only hand pressure. To assist with fitment, I beveled the inside of the spacer. No locating pins are necessary because it is an integral part of the spacer. This may work for other airsoft guns, but this is my specific model. The photos will help you determine if it will fit a non-Lancer gun.
