Undoubtedly, the Magpul was one of the first to actually put along with innovative designs a touch of aesthetics and stylish elements in the world of tactical equipment. The idea of "tactical chic" is perhaps best reflected in the Magpul line of stocks (buttstock) such as UBR, STR or CTR. The subject of this review CTR stands for Compact/ Type Restricted stock and is intended for compact applications such as shorty rifles, carbines, and PDW weapons. However, the Magpul CTR is a lightweight stock and doesn't balance out front heavy rifles well. On the other hand, the Magpul CTR's is entirely satisfactory on short barreled rifles such as 14.5" M4's or some lightweight or government profile 16" mid-length barrels.
It should be noticed that AR15 could utilize stocks with a smaller mil-spec buffer tube or a commercial buffer tube. The differences between the mil-spec collapsible stock and the commercial collapsible stock are small but crucial. These stocks are not interchangeable, and one should change out the buffer, tube, and spring. According to that, the future owner of CTR stock has to keep in mind that there are two original sizes of M4 Carbine receiver extensions (buffer tubes): mil-spec as well as commercial-spec.
Well known for quality products, Magpul manufacture CTR stock of the high-quality materials making it a lot stronger over the mil-spec M4 stock. Usually, the quality goes with added weight so the CTR with 0.55 lb. is, of course, heavier than a standard stock but also without the awkward feeling of service carbine stock. The streamlined A-frame profile avoids snagging and secures the launch latch to prevent accidental release.
Since the Magpul points out that CTR Stock is a drop-in replacement, the install is a snap and a second best feature is "friction lock" option canceling the bit of play that is evident with an M4 stock. Although the cheek weld is just about the same as any other collapsible stock, due to sloping geometry and a little extra material up top this cheek weld is better than the standard M4 stock enabling more convenient usage. Furthermore, the side mounting slots can take optional comfortable cheek risers for NON-AR15/M16 applications.
The Mil-Spec Model includes a standard, removable 0.30” rubber butt-pad while the commercial model comes equipped with an extended 0.55” rubber butt-pad to provide positive shoulder support and accommodates longer slant-back extension tubes. It is compatible with lots of Magpul receiver-mount sling attachments and also has the option to use the ambidextrous push-button QD sling mounts.
After years of utilizing AR platforms guns, many experienced users made a conclusion that it is all about a game of matching the right part with the right gun. Changing one accessory with another can severely alter how the gun feels and balances. So the primary goal is to select accessories that complement each other so that owner ends up with a well-balanced carbine that doesn't feel like a boat anchor.
