Strike Industries Enhanced .308 Ultimate Dust Cover - Capsule - Black
The Strike Industries Enhanced Ultimate Dust Cover is the world's first quick disconnect ejection port cover for the AR-308! Manufactured from high-density Nylon polymer, the UDC will never corrode, rust, fade, or deform. It features an internal True Seal lip to better protect your rifle from the elements. A built-in adjustable detent screw allows you to easily compensate for receiver wear, or increase/decrease opening power.
The spring-loaded internal detent rod provides easy installation and take down, often taking just 5-10 seconds! Features a cut-out window for easy installation or removal, without impacting the True-Seal capabilities!
NOTE: The SI UDC has been tested to fit Mega Arms MATEN, DPMS Oracle, SIG 716, YHM, and S&W upper receivers. While it is easily modified to fit other receivers with light sanding, the UDC is not guaranteed to fit all upper receivers.

Ratings & Reviews
A Poor Quality Product.
by K.R. -
Product was defective out of the box. The spring was missing a leg that makes the dust cover pop open, and the latch pin did not engage the receiver so the dust cover wouldn't stay closed. Did appreciate the spring loaded pin that made installation a breeze.
Incompatible with DPMS compact hunter 308
Bought this for a DPMS compact hunter 308, and it does not come even CLOSE to fitting. I don't know if the DPMS upper requires a specific cover or what, but this one is a good CM too small and wouldn't fit properly.
Strike Industries Enhanced .308 Ultimate Dust Cove
by Gun builder and collector
Would give this product a zero if it was available. I have three different brands of DPMS/SR25 type upper receivers. It won't fit any of them.
Not generic fit.
This item did not fit my PA 10. It would take serious modification to make it fit.
nice looking and innovative installation. did not really fit aero m5 upper well but fit saltworks upper with no mods
Better than steel, but...
by TIMOTHY MCPHERSON
Capsule styling looks great with Aero M5E1 upper and 12 inch keymod handguard, but... some fit issues and required some trimming to snap closed.
Great Dust Cover
Remember if you have a billet Mega Maten or similar the process of installing this dust cover is lengthy unless you want to risk cutting the other dust cover out.
Does not fit PWS MK2
Cannot get this to fit MK2 receiver set from PWS in spite of a lot of time sanding it down. Will be replacing with Black Rain Ordnance.
Wasn't aware that this was plastic. Not a huge deal just would've preferred metal. Probably just me not paying attention though. Most likely the second one. Still gonna use it. Solid product
Good Dust Cover
by Robert Scott
I love the SI Ultimate Dust Cover for AR-15's so I decided to go for one on my Aero Precision M5 308 build. The cover looks good but doesn't fit great. I sanded it and it fits better. I think the good looks offsets the minor figment issues. I highly recommend!
