That sounds good except....
After I placed my order with DSA, I became impatient, the DSA order took 84 days from order till delivery and ordered a complete upper from PSA (.223 Wylde). The PSA order took 10 days.
As I'm not rolling in cash, I normally sell or trade one weapon to fund the next. This has worked for me for several years, until the 6 day short of 3 month dry spell. Thus my order from PSA. The PSA upper is gone now and I am still enjoying the DSA in 300 BlackOut. Both uppers are/were very good, my view. I had a Mega lower until some guy wanted more than me $. The DSA upper now sits on a PSA lower.
I keep and play with a weapon until I have squeezed all of what I consider possible accuracy from one. Then I look about for the next.
I have recovered my investments well with AR types, not so much with some others. All in all, it is a very enjoyable hobby. With the current state of the market and uncertainties, I don't know what my next project/toy will be.
