I know it's a long shot, but I'd like to buy an ALG M-lok co-witness rail section. It will look like the pic below (not to be confused with the EMR v1 co-witness rail section.
Looking at various drop-in trigger upgrade options for my Sig M400. Geissele, Timney, CMC, Wilson, POF, ALG, will consider all quality triggers.
Let me know what you have to sell/trade.
