Set of 5 Hi-Cap 300 BB Magazines for M4/M16 Replicas - Tan

Pretty much useless. They does not lock in place, and therefore can't even feed properly.

Unfortunately they don't lock in place in the mag well. I have 5 rifles which all use m4/16 style mags and they don't fit. Compared to all my other mags the location of the mag release slot sits a bit lower so the mag can't reach the lock. I'll keep the mags and try and sell them on to someone whose gun they will fit but just to let you know for other customers wanting to purchase them that they may not fit all m4/16 variants.

Very good in my specna arms no feeding problems and very good price
