I read a Magpul notice about a "bolt catch interference" issue using PMAG on LMT MWS. It says new PMAG addressed this issue. But it does not say how to identify the new PMAGs from the old ones. Does anyone know how to check this?
The notice is reproduced below;
NOTICE: PMAG 20LR COMPATIBILITY WITH LMT MWS RIFLE
A potential compatibility issue has recently come to Magpul's attention regarding the PMAG 20LR magazine when used in a limited number of 7.62 NATO caliber LMT MWS weapon systems. When the PMAG 20LR is inserted into the magazine well, some MWS rifles exhibit interference between the bolt catch and the rear of the magazine. This can cause partial engagement of the bolt catch and result in unintentional contact between the bolt carrier group and the bolt catch during normal weapon operation. Although this issue has only been reported by a very limited number of end users, Magpul has introduced a slight modification to all new production PMAG 20LR magazines to eliminate any potential for bolt catch interference, and will begin shipping modified magazines effective immediately.
