The trigger, as well as the charging handle, magazine button, and hold open device, etc., are the same as the M16 and AR-15 rifles. LR-300MLs have flat top receivers with Weaver rails, allowing them to be used with multiple types of sights. Secondly, the return spring for the bolt carrier is mounted forward of the receiver on the extended carrier key. The LR 300 gets around this problem in two ways - the bolt carrier is half the length of a standard AR-15 carrier. This normally precludes the use of anything but fixed or telescoping stocks.

Most AR-15/M16 rifle variants have a thick, cylindrical recoil buffer tube that protrudes several inches straight back from the rear of the receiver, and the weapon cannot operate without it.

Also notable is the rifle's capability to use a fully folding skeletal stock. One stated feature of the rifle is its 'diverted felt recoil' which helps prevent muzzle rise common to most other select-fire rifles and carbines. The LR 300 is an assault rifle based on the M4 Carbine, designed and manufactured by Z-M Weapons. Their SR-25 lineup has been thoroughly reviewed on several sites, but I hadnГўв‚¬в„ўt seen too many reviews of their LR300 models, which is why weГўв‚¬в„ўre here today! Needless to say, I was very impressed with this latest offering from A&K. As impressed as I was with A&KГўв‚¬в„ўs SAW series, I knew that I needed to check out their AR series.
