Remember that thing called a “castle nut” that ensures a strong connection between your buffer tube and the back end of your lower receiver? Remember how hard it was to get your buffer tube perfectly straight up and down when installing a new one? Say goodbye to all that headache and say hello to Primary Weapon Systems, Enhanced Buffer Tube.
I am one of many consumers that immediately look up how to install products before buying them, and in some cases, the ease or difficulty will lead me to my purchase decision.
Standard Buffer Tube Installation:
There are only a few reasons to ever take off your buffer tube. If you have had the opportunity to build your own AR-15, or replaced a standard buffer tube, you know the headache that it creates. If you haven’t, let me fill you in: First you have to buy a castle nut wrench, then you have to pray that the manufacturer of your AR-15 (if you did not build it yourself) didn’t solder the castle nut to the exterior threads of the buffer tube. While praying, you are going to want to find a vice and a piece of wood. Rip down the piece of wood to properly fit inside of your magazine well. With the piece of wood inside the magazine well use the vice to clamp down the piece of wood so that the lower receiver is perpendicular to the floor. Now take that castle nut wrench you just bought and attempt to unscrew the castle nut away from the lower receiver without marring the buffer tube. Now, let’s say you get the castle nut off; unscrew the buffer tube. Not too fast, the buffer retainer that holds the spring and buffer in will attempt to fly away under the fridge, never to be seen again! Now the real fun part. Whatever reason you have for changing out your buffer tube, you now have to screw in the new one to the lower receiver (making sure to screw the castle nut, with the notches facing out, onto the tube first) while holding down the buffer retainer. Once you get the tube screwed into the lower receiver to the point where the retainer is catching on the tube you have to now make sure your perfectly straight before securing the tube to the lower receiver with the castle nut.
Enhanced Buffer Tube Easy Instillation:
- Built in QD sling mounts
- Extended lip- eliminating carrier tilt, while properly securing the buffer retainer
- Indexing screws- eliminating the use of a castle nut
- Internal Dead Blow Buffer- reduced cycle rate
I am a firm believer in the motto “if it isn’t broken don’t fix it”. That being said, I would gladly buy this product and go through the trouble of uninstalling a standard buffer. The PWS EBT is by far the lightest buffer tube I have held. Although it may only be ounces different, keep in mind that ounces make pounds and pounds create a more difficult weapon to operate. If you are a shooter that stresses on weapon weight, this buffer tube is for you. With the versatility of the QD sling mounts, operators will no longer need to stress over changing sling attachment points on the fly. Finally, one of the most important feature (in my opinion) is the precision buffer tube plate, which simplifies precise indexing when installing the product, eliminating the possibility of the stock being canted. PWS outdid themselves with the Enhanced Buffer Tube and I believe weight, versatility, and functionality were all taken into consideration with the creation of this product and it shows.
A Truly Final Thought:
Front Site Post is in no way affiliated with PWS at this time, and this is not a paid review. With that being said, I am aware of the surplus of “after market” buffer tubes available to consumers. Yet I firmly believe this product is the best on the market. I am one of many weapon owners who have built their own AR15, and I am one of many who have struggled with the now inferior castle nut and the indexing process. There may be other products in this industry that provide similar aspects to the EBT, but my hat goes off to PWS for being as creative and innovative as they were with their product.
