Primary Weapons Systems provides a limited lifetime guarantee on all of our compensators and a 2 year limited warranty on rifles and complete uppers. Your satisfaction is paramount to our success and we will do everything within reason to assure your confidence in our products and our company.
If the item is in stock the quantity in stock will show in the product description and thus we will normally ship within one (1) business day. If the item is not in stock, we will notify you at the time of your order what the expected lead time will be.
Due to ITAR Regulations, we cannot ship directly overseas and our products must go through the proper exporter/importer channels. We are currently working on setting up these channels and hope to have them in place shortly.
From time to time, PWS will make upgrades or modifications to our products. Typically this is more due to a supply issue than a functionality issue. Our enhanced bolt carrier is a prime example of this. We were unable to purchase bolt carriers so we simply made one ourselves. Any time we have to make something, we will typically make improvements to make it sexier than the original. Unfortunately, PWS cannot upgrade existing rifles or uppers at no cost to the customer. However, we do offer the upgraded components for sale on our website if an individual simply must have the upgraded version.
From time to time, PWS will evaluate the market demands and decide on new calibers. As we are not a custom shop, custom calibers and modifications are not possible. However, if a customer would like to purchase a quantity of a specific caliber/feature/type, this is certainly something that we can look into.
Cleaning instructions for the MK1 Series Rifles can be found in the instruction manual for the product. Basic cleaning can be done by simply wiping down the bolt carrier group and operating rod with a lightly oiled cloth.
The MK1 and MK2 Series rifles and uppers are designed to run with little or no lubrication. A very light amount of oil can be applied to the rails of the bolt carrier. Do not over lubricate any of your weapon components as this simply attracts dirt and makes mud.
The specific model of the CQB comp that ships with the Diablo upper is designed as part of the system and should not be removed. Removal, modification or replacement of the compensator will result in diminished performance or malfunctions.
PWS uses and recommends a standard carbine spring with an standard carbine buffer. However, most common spring and buffer configurations will work without issue. All uppers are test fired prior to leaving our facility, so if you manage to build a spring/buffer combination that causes short stroking, please correct that issue before calling PWS for support.
Since the volume of gas from the 300BLK subsonic loads is extremely small, there is insufficient pressure available to reliably cycle the action of a piston or DI weapon without a huge range in gas adjustment. This is not an issue with a suppressor attached.
As of right now, we don't recommend running a suppressor with our MK2 Mod 0 rifles. With its lightened carrier and higher gas volumes from the 7.62X51 cartridge, screwing a suppressor on that increases the pressure of those gasses and is simply going to cause function issues. This is due to the fact that the MK2 Mod 0 currently, does not enjoy the adjustability of buffer weight that the MK1 does. If you are going to attempt to suppress one of our MK2 Mod 0 rifles, we recommend using an MK216, as that rifle ships with a longer buffer tube and a standard AR-15 carbine buffer. We recommend you also find the heaviest AR buffer that you can such as an H3 or some of the even heavier offerings from heavybuffers.com.
The J-Tac47 Series, the DNTC Series and the FSC series are all considered compensators/muzzle brakes and NOT flash suppressors. All of these devices have been sent to the BATFE FTB and have been classified as non flash suppressing devices. You can view the letters here - FSC556/DTNC308 & JTAC47/DNTC.
The asymmetrical ports in our muzzle devices are important elements in the design of the compensators. Where many compensators on the market perform best when turned to the 2 o'clock position, our design alleviates this step thus the proper installation method is with the comp properly timed in accordance with the instructions on the back of the package your muzzle device was in when you received it.
While developing and running a batch of custom comps, it is rarely cost effective. Because of setup time, material, etc - the costs of 1 is very similar to the cost of 100 due to the time it takes to setup the machine, create the program and start the run - it is just as easy to run 200 of them as it is to run 1. Because of the way we produce our current comps, there is no way to take one off of the machine in the middle of the production and simply thread it differently to match a different thread. The only way to get a single comp produced is to make it by hand on a manual mill and lathe " which is not a very cost effective option. We would suggest rethreading your barrel to something more standard before we would suggest paying $500 for a custom compensator.
PWS discontinued the retro-fit system due to the overwhelming amount of inferior and non-mil spec components made available to the market in 2009. We have since developed the MK1 piston driven upper and rifles and will produce and market those from this point forward.
Tired of the tedious task of peeling sharp layers off of peel washers, PWS designed and produced the PWS Shim Set. We also sell this set to other manufacturers for use with their devices, which is why we elected to use the sterile packaging vs. the PWS logo'd packaging.
