Welcome to The Windham Weaponry Newsletter – Vol. 4 / Issue 6

Mark Eliason, VP Sales & Marketing


In this issue, I want to introduce you to something old, yet new! The Dissipator concept has been around for quite a few years and here is our version of this “Old School” configuration. The Dissipator combines full length handguards for better heat dissipation and the same sight radius as a 20″ target rifle on a carbine gas system. The gas block is concealed under the handguards and the 16″ M4 profile barrel balances out this carbine at 7.2lbs. These are available as complete rifles or as complete upper and barrel assemblies now – in both M4 profile and Heavy barrel configurations.

See www.windhamweaponry.com  for all the rifle and upper receiver assembly configurations

As always, shoot safely and feel free to contact us with any AR related questions.

We’re here to help!

TOPIC: Installing the Bipod Adapter for our Wood-Stocked Rifle Models



With this adapter it is possible to securely mount a Harris bipod to these rifles without the bipod tilting upward.

First, insure that the rifle is empty. Then install the spacer and bipod as shown.

Unscrew knurled knob on bipod so you can squeeze the clamping bar to open it wide enough to go over the bipod stud.

Once the clamping bar is over the stud, screw the knob down tight.

Cheryl Eliason, Customer Service Manager

We receive a variety of customer service related questions from our customers, and in order to better serve all of you, highlight one question each month.


This month’s question is:

I’d like to change the flash hider.  What is the thread pitch on my Windham Weaponry rifle?


Our rifles with the barrel stamped WW  5.56 NATO have a ½” x 28 thread pitch.

Our rifles with the barrel stamped WW 308, WW 762 x 39 and WW 300 BLACKOUT have a 5/8″ x 24 thread pitch.

**Please Note:  Our compliant models have a pinned and welded muzzle brake, permanently installed.  We do not recommend attempting to remove muzzle brakes on those models as it may damage the barrel.

ZCORR Vacuum Storage Tactical Firearm Bag.


Price: $ 27.95

TThe ZCORR Vacuum Tactical Storage Bag was designed to protect modern tactical rifles or other firearms with large attachments from rust and general corrosion. The vacuum valve and 100% water proof and airtight zipper closure allow this bag to be reusable and maintain its enhanced preservation qualities for extended periods of time in multitudes of environments. ZCORR Vacuum bags have a strong reinforcing layer which reduces the threat of tears or punctures. Depending on a firearm’s overall height optics, lights, and magazines may remain mounted and are unaffected by VpCI molecules. As always, optics should be stored with caps on if caps are available. These bags have a one-way vacuum valve installed that allows use of any vacuum cleaner hose to evacuate air from the bag. The Tactical Weapon Bags are the most convenient storage and preservation solution for AR platform rifles, AK’s, and other modern repeating rifles. Bag dimensions are 49″ x 14″.

ZCORR Velcro Storage Tactical Firearm Bag


Price: $14.95


The ZCORR Velcro Tactical Firearm Storage Bag was designed to protect rifles and shotguns from rust and corrosion. Depending on a firearm’s overall height, optics may remain mounted and are unaffected by VCI molecules (optics should be stored with caps on). These bags are the most convenient reusable storage and preservation solution for many modern American sporting firearms. Velcro Series firearm storage bags are ideal when there are firearms that are rarely to frequently used due to the easy closure system. Construction of a heavy duty VCI impregnated foil lamination provides years of corrosion protection, and heavy duty industrial grade Velcro closures ensure that your firearm stays in the bag and stays protected. Depending on use, firearms can be stored rust free for 5+ years. Bag dimensions are 49″ x 14″.

What’s New in LE


With summer just days away, we here at Windham Weaponry are enjoying the beautiful weather and brisk Law Enforcement sales.

I would like to let everyone know that if your Department or Agency is looking for new rifles and you have some trade-in firearms, please give me a call as we have just partnered up with a company that is now taking firearms in trade for credit towards the purchase of NEW Windham Weaponry rifles.
As I mentioned in last month’s newsletter, I will be attending the National Sheriff’s Association show in Baltimore, MD this year. I will be at the show on June 29th/30th – Booth #1275, so feel free to stop by and say hello. I will have one of the NEW 300 Blackout Pistols with me, so please come and check it out.

If you’re looking for a great reason to visit Maine in the summer time I would suggest you take a look at attending the next Armorer’s Course that is being held here at the factory on August 25th and 26th. This is a hands-on class that upon completion of the class you will be certified for 3 years. Here is the link for additional information on this class. http://www.windhamweaponry.com/le/training.asp. Class size is limited to the first 20 that sign up, so please don’t wait to send in your paper work.

If you do have questions about the class, please contact me, Todd Coons, at Tcoons@windhamweaponry.com or my assistant, Cindy Thompson, at Cthompson@windhamweaponry.com
