In 2015 the US Army began the process of replacing the M110 SASS (Semi-Automatic Sniper System) with a newer more portable system (Compact SASS). Last year H&K was awarded the $44 million contract for a version of their G28E.
Of course, with various budget issues to deal with there was, and still is, some concern about the funding for the project but the US Army continues to report that everything is a go and progressing. The interesting thing is that they have just recently reported that both the USAF and the USMC are on board for purchasing the CSASS system as well. The USAF is no surprise, but the USMC is.
We here at Sniper Central can only assume that the USMC would use the rifle as a DMR/SPR type of rifle and not as any sort of replacement for the M40A5. In fact, the Marines want to extend the range of the M40, not reduce it, and they are looking at affordable options to do that. Some ideas being kicked around include a 300 Win Mag rifle and perhaps even 6.5 Creedmoor rifles. This could even include rebarreling the M40A5 in 6.5 CM. So if the USMC adopts the CSASS we do not see them being used primarily by the Scout Snipers and STA platoons, but rather by the DMR/SPR members of the squad.
I suppose we will see…
