MMC Combos LR-308 80% Builder Sets Featuring: Gauntlet Arms LR-308 Stripped Upper
+ Davidson Defense 80% Billet Lower
+ 15" Low Profile M-Lok Handguard
A builder set is a combination of products put together for two main reasons, to kick start the builder on their journey towards a new firearm or to give upgraded parts to an already assembled LR-308. Our builder sets are special in the sense that they come with an upper receiver, handguard, dust door, forward assist (when applicable), and an 80% lower receiver. This is different from your average builder set thanks to the lower receiver being 80%. This means you don't have to go through the hassle of an FFL due to the fact that 80% lower receivers aren't serialized. You can also stay at home and we will ship these builder sets right to your doorstep. By combining the products we have, these 80% builder sets offer both quality parts at a quality price.

Includes the receiver only and does not include any other parts for assembly.
Most all the handguards on the market are for low profile uppers; just make sure when ordering your handguard it states for low profile or says it is for a standard LR-308.
It does not fit the Armalite AW-10 rifle, some older Bushmaster rifles, and some odd custom manufacturers. If in doubt, look it up most of the time the lower manufacturer will state whether or not it fits the LR-308 format rifles.

15" Low Profile M-Lok Handguard
One of the most critical components of any LR-308 custom build is the handguard. In recent years freefloat handguards have increased in popularity. The freefloat handguard covers the barrel and is attached to the upper receiver via a barrel nut. The handguard serves many functions in an LR-308 build kit such as protecting the shooter's hand from being burned by the barrel, offering the shooter something to grip to help steady the weapon, can function as the attachment point for sights/optic, can have additional accessories attached, and adds to the aesthetic appeal of the build.
It is recommended that the handguard completely cover the gas system of the LR-308 so please consider your gas system length when shopping for a handguard. If you wish to buy a pre-designed upper build kit equipped with a handguard please visit our AR-15 & LR-308 Upper Build Kits page.
