This one has probably close to 500,000 rounds through it with 3 suppressors and countless barrels..run it hard..it’s what it’s for.
To tell you how old it is? Still rocking a quad rail after all these years
It would be good to list the schedule you shot and when you replaced:
Extractor springs
Ejector springs
Recoil/action springs
Bolts
Barrels
From fleet data, there are reduced parts life that have been observed.
For those recommending adjustable gas at the gas block with set screw chokes, those will see erosion, which equates to opening the gas flow up into the system. SOTAR had a great video recently showing that on borescope on 2x 10” suppressed LE guns that had all sorts of problems (Black Rain Orifice).
They had huge ports at CLGS 10”, then tried to compensate for that with extra power action springs. Guns were beating themselves up badly, not working.
A good thing to remember about the whole deal was when SOCOM asked LMT to develop a solution, which was a regulated carrier, not choking the gas up at the block. The enhanced LMT carrier had additional gas relief to run the CLGS barrels more optimally.
I personally love the adjustability and approach with the Bootleg Adjustable Gas Carrier, which uses a flat head choke right through the ejection port. No need to remove the BCG, no need to fish into the handguard with tiny Allen wrenches, no set screws getting carbon-welded.
With a high-efficiency can, I run it fully-suppressed. You can watch the clock position of the ejection pattern change when you adjust the settings, so it really does regulate the cyclic rate noticeably.
