Description
This ejection port door is manufactured to the original Costa Mesa ArmaLite AR-10 port door overall length and is compatible with SR-25 carbines and SR-25 Cartel Uppers. This ejection port length allows more reliable ejection of cases fired from 16″ suppressed .308 uppers.
Note: This door is not the same height as the Costa Mesa ArmaLite door which was taller. The only known compatibility for this part are the above mentioned uppers. These are referred to as “Extra Long” .308 port doors and do not fit LMT rifles.

Thank you for delivery of a part I’ve needed for quite a while! Everyone and their bird dog has been needing these covers, I’m glad Griffin stepped up to help us out!

Fit and finish is superb as to be expected from Griffin. Thank you for stepping up and manufacturing parts that for the most part have been unobtainable for the last few years. Great job!

100% recommend this to anyone with an SR-25 Cartel Upper and in need of a dust cover assembly.
I spent the last 4 months waiting fruitlessly on a restock from any vendor and refusing to pay hundreds on gunjoker for a dust cover.
10/10 Griffin thank you.
