Great items
So far so good
This is one of the most compact 50 round magazines ever produced for the AR-15. The X-15 50 Round AR 15 High Capacity Magazine is engineered around our proven coil magazine technology which allows side by side staging of ammunition in a single stack. Because of our patent pending tension relief device, the X-15 can operate for an almost unlimited number of spring loads and can even perform in weapons with capabilities of up to 1100 rounds per minute. The streamlined design allows for zero separation of the ammunition during operation which prevents malfunctions and allows for an exceptionally compact profile. The X-15 is shorter than a standard 30 round magazine and three inches shorter than a quad stack magazine. The user-friendly ergonomics and ability to use a sling make this magazine ideal for 3-gun competitors. Manufactured of the highest grade materials which give it unparalleled reliability and strength. The critical components of the mechanism are coated in Cerakote for friction reduction and proven reliability without the need for lubrication.
Fits most M16/AR-15 rifles, Bushmaster ACR, SCAR 16 and Stanag rifles with improved M4 feed ramps. Variants of this versatile magazine work in 5.56×45/.223 and some 300 AAC Blackout *. May require modification to work in Robinson Arms XCR. Will not work in IMI Tavor and many Noveske receivers or receivers with modified lower magwells. No tools necessary to load or operate. Manufactured in the USA. Enjoy our no hassle lifetime warranty. If you have a problem return the drum (see warranty return link), we will repair or replace. If you aren"t satisfied, send the product back (see return link).
* 300 AAC Blackout with 208 gr bullets will work with careful loading. We do not recommend high 300 AAC Blk grain as the larger case dimensions can cause drag and improper feeding(call with questions). Soft Point and hollow point munitions are not recommended for use with the drum.
