Excellent- spendy, but recommended by Code, Verified Owner, April 17, 2020
An upper worthy for the Boog. Superior fit and finish. Handles well in tight quarters/cqb environment- pair with an SB Tactical brace to avoid ATF NFA nonsense- I recommend the SBA3, as the cheekweld is closer to the SOPMOD stocks, as the cloners kno...

Product Info for Geissele Usasoc AR15/M4/M16, 5.56mm, 10.3 inch Upper Receiver

The weapons industry standard for the last 50 years, the M4 has only had a few changes: the barrel has had some modest length changes along with some larger changes to the mounting system. However, for the most part, the silhouette has stayed relatively the same. The bulkier, more forward attachment slots on the barrel of the 5.56mm M16 have been retained, as have the carbine gas system and the free floated Super Modular Rail MK 16 handguard. All of these elements work in concert to deliver measurable increases in hit probability - an important stat to shooters who use long range tactics and M855A1 ammo. The USASOC URGI upper receiver group installs a brand new weapon onto an existing system. This upper receiver is currently in active service with USASOC. The USASOC URGI is a 10.3in variant of the Geissele URG-1.image
