MDT TAC 21 Chassis Stock by Chris Parkin
Re-assembly of the bolt-stop and its release-spring is a little fiddly as it is in the bottom of the small trigger cut-out but, a pair of needle- nose pliers helps - just don’t drop a spring! When everything is in place, small holes in the walls of the Tac 21 allow the original trigger pins to be driven back through to fasten the trigger unit in place and the two small slave pins pop out the other side - fiddly part done! Now that took about 20 minutes, most of which was the trigger and from now on, things speed up. Up to this point the action/ barrel is still a loose fit within the stock and is now bolted in with the magazine well and trigger guard section. Two more steel pins locate the components together and supplied ¼” socket cap screws/action bolts drop through the trigger guard and locate and tighten the action in place. All that is left to do is slide on the forend, fastened with three bolts and attach the desired AR-15 compatible grip, screwed on via its base with the supplied bolt.
At the rear of the chassis, where the bolt handle runs, we find a cap that has a quick detachable steel pin. When pushed out sideways, this cap can be removed to access the bolt assembly for cleaning or removal and also features the standard fitting profile for all AR-15 derived butt stock assemblies. Low Mill had kindly provided me with a Magpul system with adjustable cheekpiece and length of pull and, as this had been fitted to the end cap already, all I had to do was slide it over and insert the locking pin - job done.
