In late January 2008, Bushmaster Firearms International entered into a licensing agreement with Magpul whereby Bushmaster would take over production, future development, and sales of the Masada ...

ACR突击步枪是雷明顿公司生产的突击步枪。Bushmaster ACR（口径： 5.56×45mm NATO / 7.62×39mm M43 / .308 WIN）Masada步枪系统是MagPul公司第一个成品枪产品，首度公开是在SHOT Show 2007上。（“马萨达”是以色列古代犹太国的象征）

2023年1月16日 · Bushmaster对Masada进行进一步优化，推出了ACR步枪。 ACR步枪意为“自适应战斗步枪（Adaptive Combat Rifle）”，无论是模块化设计还是功能拓展，可速换的枪管、活塞系统都非常先进。

虽然 MagPul 公司生产有相应的弹匣，但也可以完全通用目前流行的 M16 弹匣或 AK 弹匣，只是当使用不同弹匣时，弹匣卡扣也会按 AK 习惯或 M16 的习惯而不相同。

2023年4月6日 · TLDR: If you want an ACR that's good out of the box go WE-Tech. If you plan on building one then the A&K ACR is worth considering at least it has enough going for it to compete with the WE-Tech version in my opinion.

The Sureshot USA ACR Buttstock Adapter allows the attachment of your ACR type stock or brace to your side-folding Kalashnikov* (stamped receiver)! Fixed Stock version coming soon. Comes in Long (top pictured) and Short (bottom pictured) lengths
