jtallen83 Posted September 24, 2018 Report Share Posted September 24, 2018 Did you clean the chamber real good before shooting? Needs lots of oil except in the chamber. Anything look odd on the fired cases when you get them out? Quote Link to comment Share on other sites More sharing options...

shepp Posted September 24, 2018 Report Share Posted September 24, 2018 More lube! When I first joined a lot of guys were using mobile one synthetic, I got a quart from the store and a smaller dropper bottle from ace and still use it to this day along with a few other brands Quote Link to comment Share on other sites More sharing options...
harv Posted September 24, 2018 Author Report Share Posted September 24, 2018 would never think about using motor oil and that works Quote Link to comment Share on other sites More sharing options...
DNP Posted September 24, 2018 Report Share Posted September 24, 2018 Is it cycling at all when you fire, or staying locked up on the round in the chamber? Quote Link to comment Share on other sites More sharing options...
jtallen83 Posted September 24, 2018 Report Share Posted September 24, 2018 Make sure you clean the chamber well, chamber brush the crap out of it with the Hoppes then chamber mop till totally clean and dry. Synthetic motor oil is good, something like Slip2000 EWL is even better, you need a thicker lube than Hoppes. Quote Link to comment Share on other sites More sharing options...

DNP Posted September 24, 2018 Report Share Posted September 24, 2018 47 minutes ago, harv said: It is staying locked on the chambered round You've gotta have a gas issue. The chamber may be rough, and the headspace is worth checking, but it sounds like you're not getting gas. Re-check that the gas block is on correct, check the gas tube at the block, take a photo looking into the open upper showing how far your tube extends into the upper receiver. Did you assemble the upper, what parts make up the whole system? Barrel, gas block, tube...etc. the more details you share, the more likely one of the gurus will immediately spot the issue.

suzukiray Posted September 24, 2018 Report Share Posted September 24, 2018 What happens if you just cycle rounds without firing them? Any marks on the cases? Quote Link to comment Share on other sites More sharing options...

98Z5V Posted September 25, 2018 Report Share Posted September 25, 2018 Gas tube length is good. That's one of those "in-between" barrels - the gas port placement in between Armalite AR-10 position and traditional DPMS LR-308 position. It's a 12.06" gas tube (12 1/16"), which is exactly what you need for that barrel. It's not the gas tube length, that's for sure. Quote Link to comment Share on other sites More sharing options...
Sisco Posted September 26, 2018 Report Share Posted September 26, 2018 “round not ejecting and hard to pull the charge handle to remove the spent round“ Trying to figure out what would make it difficult to remove the spent round. Tight chamber? Quote Link to comment Share on other sites More sharing options...
survivalshop Posted September 26, 2018 Report Share Posted September 26, 2018 Gas tube looks a little long to me , maybe the angle of the Photo. Makes me wonder if the Gas Block needs to be off the Shoulder , like it was set up for a A2 Hand Guard with the front cap , that may make the Gas Block slightly blocked . Is the fired case getting stuck or a loaded round ? What does your fired Brass look like , photo's ? Heavy marks on a fired case can show a rough Chamber .

Tight chamber? That's what I'm thinking. Wouldn't expect it from an Aero/BA barrel - but I just had to polish a Wilson Combat chamber in one of their barrels. That gas tube is fine, in length. That's what an "in-between" gas port looks like with an Armalite AR-10-lengthed gas tube. That gas port in that barrel isn't DPMS_lengthed. It isn't Armalite AR-10-lengthed - it's in between those two lengths (like Faxon does now on 308 barrels). That gas tube is good, and it clears your gas key when the bolt is fully closed.

harv Posted September 26, 2018 Author Report Share Posted September 26, 2018 the fired case is stuck I was thinking the buffer spring might be too stiff as the charge handle is stiff to pull back even when empty after the spent case is pulled out it has some light scratch marks Quote Link to comment Share on other sites More sharing options...

He had another pic in there yesterday, that showed a straight-down pic into the upper receiver - and his post has been edited now. That pic was edited out. Gas tube is fine.

Details. What parts, from what vendors, etc. What makes up your recoils system? The receiver etension, the buffer, the buffer spring - where did all those come from and what are their dimensions/specs? A stiff buffer spring isn't gonna cause a round to stick in the chamber. A stiff buffer spring will actually aid in extraction, over a weak buffer spring. Edited September 26, 2018 by 98Z5V Quote Link to comment Share on other sites More sharing options...
