ALL PRODUCTS BELOW WILL NOT FIT IN ANY AR15/M4 RIFLE AND ARE INTENDED SOLELY FOR THE BUSHMASTER ACR.

6.5 Grendel / 7.62x39 Adaptive Combat Rifle (ACR) Bolt - Designed, tested, prototyped, and shot to 1000 yds with the Grendel caliber. This bolt is the Argonaut's first step in making the Adaptive Combat Rifle from Bushmaster a multi-caliber rifle. The bolt has been thoroughly researched, and the applicable cutting edge manufacturing processes and materials have been utilized for the bolt. It is also plated in a silver color to differentiate it from your 5.56 bolt. This bolt is designed for use with a barrel chambered for a 0.135" bolt face recess. Available as of March 2012. Price is $95 + 5 for Shipping. Price has been changed to $95 because of a minor modification for the first batch of parts. We don't ship outside the U.S.A.

Adaptive Combat Rifle (ACR) Ambidextrous Sling Bar - Designed, tested, prototyped, and used on our ACR rifles. This bar is the ACR's first solution to switching shooting stances while employing a one point sling. The bar uses the rear take down pin hole of the lower reciever and includes instructions on removal of the original take down pin. The bolt holding the bar in place has a 1/4" steel shank and the bar itself is .225" in diameter so it is likely that your sling will break before the bar does. All exterior surfaces are coated in flat black for corrosion resistance. Available as of September 2012. Price is $18 including shipping. We don't ship outside the U.S.A.

Adaptive Combat Rifle (ACR) Skeleton Hand Guard - Designed, tested, prototyped, and used on our ACR rifles. This after market hand guard is made from sheet metal and will allow rails to be added to five sides of the hand guard. It has a good ergonomic feel and minimizes weight by foregoing an internal heat shield. It can also come with an extension for those with a long reach/grip or those rifle configurations that look better with a longer hand guard. The handguard does not use the same quick release hardware as the standard hand guards.
Options for material are steel or aluminum. Steel parts coming in at 12 ounces for the hand guard and 9 for the extension. The weight and strength of the steel parts makes them acceptable for the most intense uses. The aluminum parts weigh 5 ounces for the hand guard and 4 ounces for the extension. The aluminum parts are good for normal use of the rifle.
The hand guards are cerakoted in flat black or a coyote colors that match the ACR colors. Current price for a fully coated Steel set is $100 and they are available as of December 2012. Aluminum hand guard WITHOUT the Aluminum extension is $200 + 7, for the extension and handguard it is $275 + 9, and parts are available as of May 2013. We do not ship outside the USA.

Adaptive Combat Rifle (ACR) Adapter Plate for M4/AR15 stocks - Designed, tested, prototyped, and used on our ACR rifles. This is the ACR's first solution for using the buttstocks available for the M4/AR15 platform on an ACR in a fixed stock manner. This plate also has a bolt pattern to allow for use with a Stormwekz M4/AR15 Folding Adapter to enable the M4/AR15 stock to fold on your ACR. All exterior surfaces are coated in flat black or coyote, matching the colors of the ACR. This part was designed to function with our Ambidextrous Sling Bar. Available as of February 2013. Price is $95 + 5 for shipping. We don't ship outside the U.S.A.
