Shameless plug… I’d like to throw my offering into the ring, it keeps the weight of the handle at the OEM weight, 12g, while giving a much bigger handle for operating. Ti handle and stainless steel tang to prevent wear from the detent. (https://rxarms.com/product/benelli-m4-titanium-steel-tactical-charging-handle/)
the TTI handle weighs 28 grams, although I do admit they have a nice design, at the sacrifice of weight. The GG&G 3/4” steel weighs around the same.
this year I’ll be offering my design in 4140 hardened steel also. Estimated to be around 17-18 grams, and same locking design (which is similar to TTI locking). Probably in June 2022 I will have stock
