I don't know what the correct term for this problem is, as I am a begginner in the AR world.. but my new Del-Ton midlength rifle is having a problem. Took it to the range and shot off a few rounds with no problems. After the 10th round or so, the fired round would extract fully but the next round would not chamber correctly. The bolt did not seat all the way forward. I'd have to pull back on the charging handle and let it fly forward for the round and bolt seat correctly. Any ideas as to why this is happening? Thanks for your help. |
Brand new. Magpul PMAGs are being used... and the ammo is 223 UMC and 5.56 Federal XM193. As for the lubrication, I figured that might be the issue as I didn't lube it nearly enough as I have read recently. Hopefully that is the issue at hand. |
| Could be a short stroke problem. This is a result of not enough gas to cycle the operation. Causes could be gas port size, improperly installed gas tube, or a leak under the front sight base. Don't know if this is the case, but it could be. I had a barrel custom made recently and it was short-stroking. I had the gas port re-drilled and problem was solved. |
