Ejecting but won't lock back on last round

[hound53]

Major oopsies on my part. Yesterday pulled the buffer and weighed it and found it is a carbine buffer at only 2.9  oz. Since that lower runs fine with my other upper I went down to the local Palmetto Armory an picked up a new lower and have a Odin Works adjustable buffer on the delivery truck. Just guessing here but I think my reasoning was 180 out and a heavier buffer might cause the BCG to travel farther backwards due to inertia. I should be able to test that theory Saturday or Sunday.

Not related to this thread but I am impressed by that low cost lower. It is every bit as tight on  the uppers as my Rock River match lower. The trigger is smooth with no take up and a nice crisp reset. A bit heavy but I won't decide on whether to replace it with a two stage unit until I test it in live fire.

I have a Geissely SSA trigger with 3 sets of springs to tune  to your preference.  High Speed Match, SSA E and Stock.  
Also Harris SBRM With S lock adapter and American QD piccatiny adapter.

Just in case you want to upgrade.  

Cheers

only competition I will do with this is AR tactical prone (20 rounds in 20 min) nothing rapid fire. Too much metal in my leg for run and gun stuff. So as long as the trigger is clean and crisp I am good to go. I ahve not put a gage on it but just guessing I am thinking it's about 4 -5 lbs.

Way offtopic but the reason I decided to give the PA lower a chance was this year a buddy won the mid range 600 yard club championship shooting a bone stock PA in .223 Rem. He shot 3 cleans for a perfect 600 score. I forget how many X's but he came damn close to setting a national record with that rifle. He beat my Wilson Combat barreled upper on a Rock River match lower 6.5 Grendel as well as several other competitors using high dollar AR's. As my daddy said it ain't so much the arrow as it's the indian holding the bow
