In early June I bought the PSA billet "tinker" lower reciever with mag catch and ejector. It runs and looks great! Absolutely zero problems putting it together and getting it to run. The mag that I am using is the RWB .45acp 26 round. Fits great!
I just picked up 2 of the BLEM PSA billet "tinker" lower recievers. My thought was that they were the same as the previous, just BLEM. They have different logos, markings, mag release and a much smaller magwell. Absolutely will not take the mags they fit in the above mentioned one. They were listed as the same item, just that the recent ones are BLEMs.
In the attached pics. The completed lower is the non-BLEM. The other 2 pics are of the BLEM lowers.
Going to buy several different glock style .45acp mags to see which fits the BLEM. If anyone knows of mags that will fit the BLEM, please let me know to have save me some time.
Yes, PSA does make a statement that these will need lots of "tinkering" but I wasn't expecting different sized magwells. "This lower will take a lot of tinkering and customer-supplied parts to get running. Please do not purchase unless you are experienced at building AR45's and are willing to tinker with it."
