A5 Buffer & Spring for future 12" SBR

[RANGER]

My upper is built with the 12" Group Buy barrel and an Odin Works Adjustable Gas Block.


Thanks

Please note that Odin works makes their gas blocks to use with their barrels (which butt up directly against the shoulder). To line up correctly you may or may not have to allow for a slight space (usually between .025" and .03125") which is usually the space of a hand guard cap.

Key word is "may".

Some gas blocks do fine....others can cause a FTF because of gas port misalignment.
