This drop-in upper attaches to an LR-308 lower assembly. Comes complete with charging handle, bolt and bolt carrier assembly, it is ready to pin to a complete lower assembly without modification. The A3 is a Flattop upper that gives the shooter versatility when it comes to mounting accessories or optic devices. This upper features a free float handguard which is attached to the receiver only and does not contact any point on the barrel. This reduces the chance of accuracy-reducing pressure on the barrel.
