Description

Next Level’s NLX ASC308 LH Upper Receiver:  The perfect blend of Ascend style and Next Level quality.

If you’re looking for the best AR10 upper to start your build, then look no further than the Ascend 308 left hand billet upper receiver. Precision machined from solid block 7075 aluminum to exact tolerances, you won’t find a better upper for your AR10 rifle. 

Whether you hunt or want long range precision at the range, start your next build with Next Level quality.

Cut to match our ASC308 ambidextrous lower receivers, our uppers provide a solid platform for your next rifle. The NLX ASC308 LH upper receiver is DPMS Gen1 low profile (.150 tang) pattern.    Please feel free to contact us with any questions regarding compatibility. 

Add a NLX308 Ambi Charge Handle and a NLX308 LH BCG to complete your upper.

*NOTE:  Due to the relief cut for the dual bolt catch design of our lower receivers, our uppers do not use a dust cover.*

Upper weights 10.8 oz.

***NOTICE***  Our current inventory of LH Uppers was produced with an upper rail height difference that will lead to a slight step between the upper and a standard DPMS pattern low profile handguard- Our handguards were machined to match this run of uppers.  We have more in production that conform to the DPMS low profile pattern and will be compatible with any DPMS low profile handguard *****
