What does XCR™ stand for?
We're not really sure. It could stand for "eXchangeable Caliber Rifle"; or, perhaps, "eXtremely Cool Rifle"; or, maybe, "eXraordinary Combat Rifle". Other meanings could be "eX-treme Combat Reliability", or "eX-treme Combat Rifle". All these meanings are appropriate.
Where is the XCR™ Made?
The rifle was designed and is manufactured completely in the U.S.A. When you by from Robinson Armament Co., you support U.S. Industry.
Does the rifle have an adjustable gas system?
We are shipping all XCR™ rifles with a Five-Setting, Quick Adjust Gas System. No tools are needed other than the tip of a cartridge. There's even a setting specifically for the use of sound suppressors.
What kind of bolt does it have?
The bolt and extractor of the XCR™ is more like that of an AK47 than that of an M16. The XCR uses a proprietary three bolt system with an proprietary extractor. This bolt and extractor combination provide extreme durability and reliability.
Where is the charging handle?
The charging handle is very much like that of the FAL. It is a non-reciprocating handle located on the left side of the rifle. It has a forward assist attached to the handle. Because the XCR™ functions so reliably and does not foul itself, the forward assist is used mostly when partially opening the action to see if a round is chambered.
What Other Stocks will fit the XCR?
We manufacture two stock "adapters" for the XCR. These adapters are made for stocks based on the M4 collapsing stock used on the M4 variant of the M-16 rifle. All the M4 variant stocks slide on a buffer tube. There are commercial and military spec buffer tubes. Our M4 Collapsing Stock Adapter and our M4 Folding/Collapsing Stock Adapters will accept both the commercial and military buffer tubes. This means that most stocks intended for M4 type rifles can work with our stock adapters. You can use M4 type stocks made by VLTOR, Magpul, etc. When buying a stock, make sure the plastic portion fits the buffer tube. It's best to by both the plastic stock part and the buffer tube from the same manufacturer. Though M4 stocks will fit on the XCR, they are quite wide. We are working on a thin profile stock which both folds and collapses. It will be available early in 2009.
What does it take to change calibers on the XCR™?
Only the bolt, barrel, magazine and brass deflector need to be change to change calibers. It takes less than 5 minutes for the caliber conversion.
What threading do XCR™ Barrels Use?
The 5.56 NATO barrels have a 1/2 x 28 TPI thread, the 6.8 SPC and 7.62x39mm barrels have a 5/8x24 TPI thread. Most M-16 muzzle devices will work on the 5.56 NATO barrels. Most .308 muzzle devices will work on the 6.8 and 7.62x39mm barrels.
What magazines are compatible with the XCR™?
For 5.56 NATO (.223 Rem.), M16 magazines can be used, including the drum magazines like the Beta - C mag. For 6.8 SPC, a special 6.8 magazine is used. They are made by C-Products, LLC and Precision Reflex, Inc. For 7.62x39mm there are 10 and 30 round magazines. The 30 round magazines are made by C-Products, LLC.
Why doesn't the XCR™ come with sights?
The XCR™ does not come with sights because decent sights are very expensive. Most flip-up, co-witnessing combat sights range from $100 to $200 per sight. Because of the expense of these sights, we don't force the purchaser to choose. We do currently offer Midwest industries sights. You may also want to consider Troy Industries, ARMS, and other sights on the market.
Though the rifle doesn't come with sights, you do get a 1913 Standard Rail at the 12:00, 3:00, 6:00 and 9:00 positions for no extra charge. Compared with other similar products, the XCR™ is a steal.
