I have several demilled kits from police surplus guns perfect for an SOT postie build or for spares on semi-auto guns. I can remove any F/A parts from lowers if you want to use them as semi-only and aren't comfortable with doing so. "features a 10” button rifled barrel, chambered in 5.56mm NATO, with a twist rate of 1 in 7"
These are parts kits and therefore not considered FFL items and also be sure and understand NFA rules. Note: while the bolt carriers and lowers are F/A capable, using them on a semi-auto doesn't change the status as semi uppers have blocking features in place to prevent auto and burst features. Every 556 SigSauer has made in the US already comes with a F/A capable bolt for example.
I also have two SigSauer rear diopter sights available for $250/ea with a kit. I'll make those available separately if not sold when all kits are gone.
$2400 for M4 style and $2600 for Swiss folders (use real alemann-agch Swiss-made stocks...worth $4-500 on their own) + actual shipping (should be $25 or so plus any insurance with a USPS Large Flat Rate Box). USPS money orders, personal/business/cashiers check or discrete electronic methods for tenured members of sturm (venmo or zelle)
