The construction of matched receiver sets are explained in a good way over here. I am having ar15 gun and looking for some matched receiver sets and other components for ar15. Please do share something more for me for getting these receiver sets. matched receiver sets
Our uppers and lowers( thereby the matched sets also) are built to exact Mil Spec requirements, using forged 7075-T6 aluminium components. The uppers and lowers are hard coat anodized black per Military Specifications, and care is taken to ensure matching shade/coloration.
I hope this answers your questions. If there is anything else I can get for you, please let me know.
As it shows on our website, we are out of stock at this time on matched sets, but we do have more in-process at this time. I cannot give exact delivery times, however.
