6.5 Grendel 18" Lightweight Complete Upper

All Alexander Arms® upper receiver assemblies are fully-complete, function-tested, and ready to fire.

Q1.	Is this product compatible with my AR-15 lower receiver?
	All of our upper receiver assemblies will fit on and be compatible with any standard-specification AR-15 lower receiver. No fitting or modifications are needed. If your lower receiver is made to standard AR-15 specifications, our products will work perfectly. We do not catalog all compatible lower receiver assemblies as this is not possible. We cannot confirm whether your lower receiver assembly is considered standard or mil-spec; you should contact the manufacturer to confirm this.
Q2.	Will this product require me to replace the buffer or buffer spring with something heavier/stronger/different/better?
	No, replacement of the buffer or buffer spring components is not required and they should not be replaced unless they are non-standard. Please review Question 1. Our products are specifically designed to use these particular, standard components and no others just so that owners do not have to make specialized changes to their standard receivers. Replacement of these standard buffer components when using our products will not reduce recoil, help the weapon manage the higher recoil in any way, or help the weapon cycle better. The only possible result is the failure to cycle ammunition properly because you will have removed the parts required to operate the weapon properly. Specifically, the correct buffer types are A2 in full-length receiver extensions and H2 in carbine-length receiver extensions.
Q3.	Can I order this product?
	Yes, you can.
Q4.	Does this product have to ship to an FFL-holder?
	Upper receiver assemblies are not regulated in any way by the BATFE. They are not serialized and cannot readily fire ammunition by themselves because they do not contain a fire control group. Therefore, their shipment is not prohibited by any state or locality in the United States or its territories. Please be aware of your state's regulations for certain firearms components, such as magazine capacities and muzzle devices, before ordering.
Q5.	How do I remove the handguard? How is the handguard assembled? Of what material is the handguard made?
	Please understand that we cannot directly assist customers in the disassembly of our factory-assembled weapons. Our weapon systems are designed and built to last many years without loosening or breakage of components. The handguard is made of G10 fiberglass composite material and is permanently-affixed to the barrel nut. The handguard is not made of aluminum or carbon fiber.
Q6.	Does the 6.5 Grendel use special AR-15 parts that are installed in special ways?
	Aside from the barrel, bolt assembly, and magazine, our 6.5 Grendel weapon systems do not use specialized parts. The parts are not installed in special ways. Our 6.5 Grendel weapons are built just as any AR-15 weapon is built. We do take measures to ensure that components are installed so that they last many years to come. This includes many adhesives and other materials that prevent the weapon's components from loosening during regular use.
Q7.	Can I order this product without a certain part installed?
	We do not produce or sell incomplete weapon systems. All weapons are sold as described: 100% complete, fully-functional, and fully-tested assemblies.
Q8.	Does this product include a bolt and carrier group?
	As you see in the product description and other locations in the Online Store, this weapon system and all weapon systems we produce are 100% complete. We do not produce or sell incomplete upper/rifle assemblies.
Q9.	Will Alexander Arms® build a custom weapon, component, or option for me?
	We do not build custom weapons, components, or options. All available products, parts, and options can be found in the Online Store. If an item you wish to purchase is not displayed, it is not produced, sold, or offered by Alexander Arms®.
Q10.	What level of accuracy will this weapon achieve?
	This product is not provided with an accuracy guarantee. However, customers commonly report sub-MOA accuracy with all of our weapon systems.

Don't forget your ammunition and extra parts! - This upper receiver assembly ships with one 10-round magazine. Visit the products below to add more to your order. If you are choosing the MK10 handguard upgrade, be sure to add MK10 rail sections for your handguard! We strongly recommend that you also add ammunition to your order instead of placing a separate order to avoid lengthy ammunition back-order situations.

Rating:	4 of 5 - Good
Pros:	Under .5 inch accuracy Hard hitting Reliable
Cons:	Front swivel/sling screw constantly backs out of fiberglass forend. I consider this problem to be a significant risk of damage to the rifle/scope if it comes out, and would have otherwise given it rating of 5.
Comments:	My 6.5 Grendel 18" upper is pinned to a Stag lower with a Geissele SSA-E trigger and topped with a Vortex Viper Scope. Loading with Hornady 123 gr SST, it has been very effective at harvesting both deer and hogs.
